Sigma had no reason to live. Afterall he was created three years ago by that stupid book..having nothing but the clothes on his back

eventually fyodor and the decay of angels became his family. Giving him what he sees as his life's purpose. The Sky Casino.

everyone sees him as calm and capable,being the perfect manager and leader. In reality he's not..that was easily proven when he had to deal with the ADA and the Hunting Dogs.

once you joined the decay of angels everything changed. Yes he had what he called his family..but he desired something more. Beyond a family.

someone to call his own. Something permanent to his name.

that's what you soon became. His. He'd sacrifice the casino to keep you. You're priceless to him. Afterall you're who he deems home now
