SO my first true FanFic! And I am going to kick it off with a *drum roll* CROSSOVER! The reason I am posting it in the Halo section is becouse I want to keep the X-over a secret untill about the 5/6th chapter, however someone who has a small to mediocre understanding of the lore of the other universe will almost immediatly (Either the first or the second chapter) know what the other universe is. Now without further ado CHAPTER ONE!

CHAPTER ONE: We've found him!

4th April 2557

"Well thanks Mike! Sheesh. What a prick." Tim Romero sat down behind his console on the bridge of the USFC (United Species Fleet Command) In Memoriam, the second ship of the new Keyes-class dreadnoughts, the first class to fully incorporate the technological advances obtained by allying with the Sangheili. The ship was currently on its way to rendevous with a fleet of mixed Sangheili/Human ships. Tim's job as a comms officer means his is usually seen as 'non-essential personnel' by the rest of the bridge crew but without him, they wouldnt be able to call home. "Lets see if he didnt ruin my console." Tim said as he pressed the on button. After a second the holo panel flared to life:

Booting....

Booted.

Scanning for signals....

Recieving distress signal....

Scanning for signal profile....

Signal profile detected....

Retreving archived signal profiles....

Match found and confirmed.

Signal matches recorded UNSC Frigate Forward unto Dawn signal profile.

Alerting ship CO as stated in Article 3, Paragraph 9 of the Hood Protocol.

"Captain Anderson, report to the Bridge immediatly. Repeat, Captain Anderson to the Bridge immediatly." Avina, the ship's AI broadcasted across the ship's PA. A minute later the captain came unto the bridge in training fatigues. "Whats going on Avina?" Anderson asked the AI. Tim responded before Avina could. "Sir, I.. Think.. I've found the Master Chief Sir." All of the Bridge crew, including the Sangheilian weapons officer, spun around when they heard the news. "What?! Let me see." Captain Anderson bent over the Comm officer's shoulder reading the message's last two lines floating in midair. "By all that is holy. Avina, get me a direct link to Lord Hood! Priority one!" It didnt take long for Lord Hood's face to appear on the screen in front of the bridge sparking salutes from all the personnel there. "Captain Anderson? What could possibly be important enough to get a P1 comm link to me?" "My comms officer has picked up the distress signal from the Forward unto Dawn Sir." "The Dawn? This is not a funny joke Captain." "I am not joking Sir. We are transmitting logs now." "Recieving... My god. Captain, I am ordering you and the In Memoriam to divert to the location of the distress signal immediatly. Am I clear?" "Crystal Sir." "Good. Hood Out."

"Avina, set a course using the Signal's coordinates and engage Slipspace drive." The captain ordered while heading out of the bridge "I am going to get my uniform." "Understood Captain. Course laid in and Slipspace drive engaging." The space in front of the In Memoriam ripped apart, the ship sliding into the alternate dimention known as Slipspace, where Faster Than Light travel is possible. "ETA 3 Days, 15 Hours, 23 Minutes. Recommend Cryo-Sleep for non-essential personnel." Avina's voice rang out form the PA system again. "Looks like you have to go to bed Romero!" Mike Sullivan, the engineer, teased. "It looks like you are going to run the night shifts during the Slipspace travel Petty Officer Sullivan." The captain casually spoke while walking back unto the bridge, this time in uniform. "Yessir." "Dismissed." The captain sat down in his chair. "Avina update Petty Officer Sullivan's shift roster accordingly." "Yes Captain." "Everyone back to your stations."

3 Days, 15 Hours, 22 Minutes and 50 Seconds later...

"Exiting Slipspace in 10 seconds Captain." "Alright. Bring us out." The ship snapped back to Realspace, the stars becoming visible again. "Full scan." "Scanning... We have arrived in a type five solar system. 6 planets in scan field, gravity fields suggest one more planet behind the sun. Planets currently scanned show two terrestrial planets in the innar solar system one in the outer system and 3 gas giants, one in the life zone, two in the outer solar system." "Alright. Where is the signal coming from Romero?" "It's coming from that gas giant in the life zone. But it's in a stable orbit so it must be coming from a moon." "Set a course Avina." "On our way Captain." The ship's engines flare sending it towards the inner solar system. "I want a detailed scan of the gas giant. Composition, Size, Colour, Moon Count, everything."

"Getting moon count now Captain. Only 15 moons, one is about 9/10ths the size of Earth. Atmosphere is comprised of nitrogen, oxygen, CO2 and a large amount of hydrogensulfide and xenon. Same thing for the gas giant, minus the all the oxygen and half of the CO2. And boy is she pretty, putting up a visual."

A beautiful sphere of greens and blues crossed with white appeared on the main screen, against a background of its deep blue mother planet and the black of space. A massive storm on the gas giant appeared to look straight at the moon, strangely being the only visible storm. "Like a kind of cyclops" One of the bridge crew mused. "Perhaps we should call it Polyphemus."

"And the signal is coming from that moon. But the hydrogensulfide/CO2/xenon combination makes the atmosphere unbreatheable. That there is oxygen however compensates, so the air only needs filtering." The captain nodded. "Avina, get a squad of ODSTs ready for drop." "Sir, there are extreme magnetic fields all over the moon interfering with signals. We would have a very hard time tracking the team as well as being compleatly unable to track the distress signal from the Dawn." "Hmm. That makes it very difficult to mount a large scale operation. Avina are you thinking what I am thinking?" "If it involves the words 'firebase' 'pods' and 'prep' then yes Captain" "Good. Drop in the squad of ODSTs and prep pods to get a firebase up and running the moment they find a big enough clearing." "Yessir alerting ODST Alpha squad now. They are on their way to the drop pods." "Drop them in on the largest continent." "Yessir" "This is Lieutenant Edward Buck. We are ready for drop." "Confirmed Lieutenant. Dropping pods in three... two... one..."

Six very soft *clunck* sounds reached the bridge crew.

"This is ODST Squad Alpha, we are inbound to surface. ETA twenty seconds." "We will not be able to keep comms open so you are pretty much on your own untill you can signal for the firebase." "Roger that Captain." "Alright then. Godspeed."

I am also looking for a beta reader.
