Meanwhile in another world
Inside of the nazarick, Ainz Ooal Gown at his throne with his subordinate the Floor Guardian. Albedo, Shalltear Bloodfallen, Demiurge, Cocytus, Aura Bella Fiora and Mare Bello Fiore bowing their one knee to their lord and master.
Albedo: so our plan for now is to manipulate the kingdom of riesty from the shadows, while symbiotically forming an alliance with the baha root empire, once we balance these two operations we'll achieve our ultimate goal making the sorcerer kingdom of Ainz Ooal Gown the gloable superpower, seated at the great tome of Nazarick.
Ainz Ooal Gown: I admire your ambition albedo.
Demiurge: Lord ainz.
Ainz ooal gown: what is it Demiurge?
Demiurge: Well my lord i have a matter of interest.
Ainz ooal gown: By all means enlighten us.
Demiurge: It's seems, there been some rumors of a strange phenomena Currently the very wall of nazarick.
Ainz ooal gown: A strange phenomena you say?
Demiurge: exactly, I have yet to witness it the anomaly myself, but as I heard it told, two small boxes suddenly appeared out of nowhere, but as it shown in dormant, is a simple button, one has a red button and the other has strange markings around the face of the device.
Ainz ooal gown: could it be some kind of weapon of one of our adversaries?
Demiurge: as the risk of sounding overconfident, I cannot envision our rivals entering Nazarick undetected.
Ainz ooal gown: understood, but though there are many things outside your imagination, we must consider many possibilities for it's origin and use. But tell me, what dose this second box look like in detail?
Demiurge: do the symbol and the marking i witness right here.
He pull it out from his pocket to give it to his lord. It was a symbol of stars but with 2 infintit mark, both X mark of a sycthe and fist and a blue omnitrix symbol and the third is a symbol of chaos with angel and demon wings and the symbol of the nemetrix.
Ainz ooal gown: I see, Fellow of nazarick! If any of these mysterious buttons are e concussion handling them if someone find one use the messages spell to share it location and follow our trap colacal.
Everyone: lord!
Ainz ooal gown: Of course I imagine you would take those same steps without me telling you.
Albedo: Your words honor us my lord.
Ainz ooal gown: is it really a trap? I mean it seems really obvious like something a kid can come up with, but you have to be pretty stupid to press a random button if you didn't know what it'll did. that's a total noob move.
Meanwhile
