I'm having some trouble with the Android's background, because I'm trying to do his racial background and abilities as well.

I'm thinking that the Androids were created by a race that used them originally as laborers and soldiers, doing the most dangerous and difficult work. But that race killed themselves off in a brutal war. I'm also thinking that they can connect telepathically and transfer their memories on their own homeworld. But then I realized that would make them essentially immortal. 

Do you have any ideas to add since you have a character from this world too?
