About the AU
Your name is KARKAT VANTAS, and you are about 12 sweeps old (26 human years).
After beating the game, your group proceeded through the door at the end into the new universe. Some time after, you find yourself living in a SMALL NEIGHBORHOOD in COLORADO with your moirail Nepeta. You decided to help her out after her old moirail practically ditched her, and you don’t regret it at all.
You work at a nearby INTERNATIONAL AIRPORT as a FLIGHT ATTENDANT. As such you are constantly gone from home on trips around the fucking world, and you try to bring back little trinkets and souvenirs from the places you visit for Nepeta.
You were able to keep all of your weapons and items from the game when it ended, and so you still have access to the Trollian network. Your trolltag is commercialGeneticist, and you speak in a manner that is ALMOST EXCLUSIVELY ORNERY, ALL THE TIME.
