- Abel/Ethan before The Alliance: His decisions leading up to his joining; the expectations of his father; his time in Navigation training
- Cain/?? before The Alliance: Possible meanings behind Praxis' slur of "gypsy"; reasons for why Cain became a fighter
- Edit: I am also considering tying idea 1 and 2 together somehow, like having them be two separate parts and then bringing it together where they become navigator/fighter, but we'll see where this particular thought direction goes when/if I start writing it.
- Cain/Abel pony-play: inspired by the very delicious artwork by hamlet_machine in the SF extras
- Cain/Abel AU: Abel is a senator and Cain is his kept boy. After getting tired of Cain wearing clothes that are ill-fitting and don't fit, Abel takes Cain to his tailor to get fitted for suits. When it becomes a ritual for Abel to choose what Cain wears on a regular basis, the process becomes a serious turn on for Cain. Sex ensues.
Just a few things that I have been thinking about in addition to the story I am waiting to post as it goes through editing (I am excited to share it with the SF community :D). May add to this list, may not.
