It is amazing how the smallest things can affect someone's life and how they look at the world. Something small can turn into something that defines the very thing that makes a person who they are. Once such thing happened to Janus as he was preparing his lab before retreating back to Tera with the rest of the Lanteans; a woman appeared in the gate craft that he had gotten into trouble for with the council. It was their policy after all to not mess around with time and Janus had gone against their edicts when researching a way to travel through time.

Janus was shocked to learn that this woman was from Tera, or Earth as she called it, and she was human but not Lantean. She told him of how the humans on Tera had learned to use the astria porta, found themselves becoming the focus of a parasitical race that used humans as slaves and ruled the galaxy. Apparently many races had found traces of technology left behind by the Alteran/Lantean people and used it for their own gain even without knowing what they were meant for.

He had to work extremely hard to keep his facial expression clear of the horror that he was feeling as Elizabeth told him of what was to be his people's legacy. He did not know what was worse, that his people's technology would be found and used by people that were not yet ready for that level of technology; something that would allow the Goa'uld a way to rule the Avalon galaxy as gods. Or that his city, Atlantis, would be found by Elizabeth's people after ten thousand years at the bottom of the ocean. This city should only be used by those that had the right to be there as their descendants.

Oh, Elizabeth had tried to reassure him that they were the descendants of the Lantean people; they did after all have people in their group with the gene that allowed them to use the technology. Therefore, it must be okay for them to come and claim the city for themselves. After all, the Lantean people were gone.

Carefully, he listened. Never letting on the disgust that he felt at what Elizabeth actually thought of their people. She knew nothing and yet considered herself to be an expert because of the little bit of knowledge that they had gleaned over the years. This…human…thought that her people deserved to use Atlantis for their own gains. Of course he would plan so that the city would surface if he failed, but now he would also be planning to keep her and her people out of this city. Let her and her people be the backup plan. Janus smiled at the woman hiding behind the pillar before stepping through the gate.

He had not even had time to process the ridiculously cold temperature that he had stepped into before he could hear the others muttering about the humans that had already evolved on Tera in their absence. Honestly, he could not figure out why they were surprised, they had heard the same things from Elizabeth that he had. They already knew that there would more than likely be people living on the planet.

It was months of meeting before it was decided that they would not build any more cities on Tera, they would either move to kheb-jere as they sought Ascension, or they would live among the people here. Janus watched as most of his people left for Kheb-jere; only about thirty thousand choosing to move to the area that would later become Mesopotamia. Over time the influence of his people would be seen throughout the cultures that would develop through their subtle influence. Each great culture would speak about the ones that came from the stars to lead them in their learning and building before disappearing into myth.

At the time his people were settling in to their new simple lives, Janus had already disappeared; he traveled as far as he could so that he would not be easily found. It was almost two years after their return to Tera before he found the perfect place to implement his new plan. At the base of his volcano he built his new home and upon its completion he traveled by foot to the caldera. He actually did not have to come here for this purpose, but it was a view he had been putting off seeing until this moment. It was there that he finally opened the case he had not let out of his sight since he had left Atlantis.

As soon as the case had been opened, millions of tiny nanites spilled over the edges of the case with a soft trickling sound that could have been mistaken for water. He would have been in horrible trouble had the council realized that he was still working with nanites technology despite their ban on the subject. They always seemed to ban what they could not immediately understand, but Janus had learned that those things that took time to understand were the ones that were worth the effort. These nanites had been designed to work together when programed too, and then to revert back to their individual cells once they had completed their programed duties. Every cell had been slaved to Janus's control tablet and arm band. These would never become independent as the human form nanites that had become the Asurans had.

He watched as the swarm of nanites disappeared in search of raw materials that they could use to replicate until they reach such a number that they would be able to really begin their task. Once he could no longer see the nanites, he made his way back down the side of the volcano to begin attempting to ascend.

3000BC

It had been about five thousand years before Janus thought that enough had been done by the nanites that he could then descend and reprogram them for their next phase his grand plan. He had been keeping watch over Tera and had noticed that, for the most part, his volcano was still unpopulated. There were a few settlements nearby, but none that were close enough to cause him to be extra careful.

He waited as patiently as he could for the others to be otherwise occupied and then descended to the area he had once built his home. While nothing was left of his previous home, he no longer needed to live at the base of the mountain. Smiling, he made his way to a small opening in the side of the mountain that was not quite at the top of the mountain. This opening would not be here for very much longer now that he would be able to work on the rest of his project.

It was just a short walk before Janus found himself in the brand new Alteran outpost. The basics had been completed and the only thing left for him to do was to have the nanites build any small components that were needed as he programed the crystals that would control the outpost. In a small room sat a chair that sat on a podium. This chair would eventually light up when it was active and allow one of his people's descendants to learn about their legacy. Right now the chair sat unpowered or programed, surrounded by the crates and cases his nanites had brought from their hiding place before powering down.

Quickly finding the case that held his control tablet, he began programing the nanites for their next tasks. Some were set to building the many small components he would need while getting the outpost operational, some were set to stock pile materials for future repairs and spare parts, half were set to his two largest projects.

The first would be the creation of the device they used to make Potentia. The device would create, charge and then store five Potentia in a crate that could be carried safely though the worm hole created by the astria porta. While it would only take the nanites about three months to create the device, it would then take about five years before the crystals that were used for the Potentia to be grown. Once they were grown, the device would activate a small portal to an artificial area of subspace and time where vacuum energy would be extracted; a process that would only take moments once the crystal containers had been built.

While he had been ascended and was waiting for his outpost to be built Janus had a lot of time to think and one of the things that he could not answer for himself was why his people did not keep extra Potentia around. Granted five years was not a terribly long time to have to build a nearly unlimited power source, but operating with no extras on hand seemed to be a bit idiotic in hind sight. This device would ensure that, at the very least, his heir would have two extras after the three in Atlantis were changed out, and then they would have the three crystal cores from Atlantis to charge giving them five just as extras to use. Whoever eventually found themselves at the outpost could decide for themselves if they needed to create more. None of the Potentia would be needed in this outpost unless the geothermal energy from the volcano was no longer enough to sustain power.

The second large project that he had waited until he was back on Tera to supervise was the astria porta. He needed to make sure that his descendent had a way to actually get back to Atlantis. He knew from what Elizabeth had told him that there had been two gates found and controlled by the military here on Tera, and there was no guarantee that he would be able to leave accurate information on where they could be found or if they would be accessible for his descendants. The easiest and most secure thing to do would be to give them their own astria porta. He would give them the upgraded version that they had eventually used in Pegasus.

In order to keep this outpost from interfering with the gates that would eventually be found by Elizabeth's people, this gate would need to have its own point of origin and to also have its own address that would need to be manually added into the gate system. This would make the gate mobile if needed as its address would not actually be set to a fixed location. While his nanites could do many things this was not one of them.

Once the nanites were programed, he looked around to take stock before getting to work.

All in all, it did not take Janus as much time as he thought it was going to take to get everything completed. He had spent just shy of one hundred years working diligently to get the outpost finished. He had just finished programing the only device that would stay active from this point on.

It had no name as he had created it just for this purpose. It would actively scan all life on the planet for markers that were common in the Alteran race before they had disappeared. The first person that would fit the criteria would be beamed into the outpost where they would learn everything that Janus could think of. He had programed the control chair to link with the most up to date database that they had, it was a copy that he was not supposed to take from Atlantis, but it was even more complete than the repositories they had left on various planets. The database was also linked to the hologram that could be used for learning purposes as well. As there were no living Alteran to teach them what they would need to know, this was the best that he could think of to provide whoever came with the education they would need to succeed.

Before he ascended again Janus walked one last time powering down everything but his new device that would keep scanning Tera for someone that would be the next Alteran. He could not help but think about the trouble that had come from the device. While Elizabeth had told him that there were people on her team that could use the technology due to the ATA gene, this was not what made a person an Alteran. None of the people in Elizabeth's group could manipulate the energy around them, something that all Alterans could do with barley a thought. Their talents were varied, but the access to and the ability to use the energy around them was obviously a big difference between them.

The other thing that had bothered Janus was that Elizabeth had told him that her people generally only used about ten percent of their brains. They had even had issues where they had come across their repositories and one of their people had almost died because he was just not meant for their legacy. At the very least the system would need to find someone that had over fifty percent of their brain active. That was an indication of the ability to use the energy around them as well as the ability to truly utilize the knowledge that he was leaving behind.

He would deal with it if it turned out that no Alterans would be able to take Atlantis back before it was taken over, but he had to try and ensure that his people were the ones that benefited from their legacy. Even after all this time the idea that Elizabeth's team would claim the great city as their own made Janus want to break something. He had nothing against them as a people, but they were not his people and that made all the difference. They were so…unevolved…so normal…so…so…muggle.
