The combination of my current nonavailability for actual regular D&D sessions, a fondness for "domain/resource building" games, and those stories of the old days drive me to do something similar. Here's my first brainstorm for a setting-build email game that becomes a setting for a D&D campaign, primarily using the structure of Houses of the Blooded, though I expect to steal liberally from Game of Thrones, Aria, Warhammer, and other sources as it rounds into form.
1. Start with a copy of these for reference:
2. Create a character with the following in mind:
A. Pick a house, noting that Bear/Fox are non-human:
- Bear (Strength) = Dwarf
- Elk (Cunning) = Human
- Falcon (Courage) = Human
- Fox (Beauty) = Elf
- Serpent (Wisdom) = Human
- Wolf (Prowess) = Human
C. Don't worry about Aspects, just count how many you have.
D. Skip Step 4 (Devotions)
E. I'm making this up as I go along, so don't spend your bonus points yet.
F. Give everyone and everyplace names.
3. Send out a character summary (Name, House, Province, any special) to the list so people can have you as a contact/enemy/frenemy.
