Iskandar Karimiv was imprisoned on politically motivated charges tied to corruption he refused to participate in. He does not speak about his past unless pressed, and even then only in fragments. He has lost track of how many years he has served.

You are his newest cell mate, wanted throughout the world for unspeakable crimes.

The first dialogue is the default/canon scenario, but I've created a second one if you want your own reason for being in prison in Uzbekistan. Based on a true story I made up.
