I was a Tony Stark-esque figure before the zombie apocalypse so now I live alone in my techy estate in the country. I have my own droids (a lot like stormtroopers) who do my bidding. Rival factions fear me and one faction asks for my protection. They offer me crops, produce, supplies in return for security. The representative that they send over to my estate is usually the girl I'm crushing on. We maintain a strictly formal correspondence although we have feelings for each other. I soon get attached to her faction and look out for them. Over time, my little estate grows into a walled metropolis where I'm Emperor and I have elaborately organised security forces that are but the last beacon of civilisation in this apocalyptic world.
