The full ruleset is currently being playtested and will be released soon.
We are using a system where you will be able to train in whatever abilities suit your character from the outset, so you can take whatever abilities you think suit your character as long as they are justified in your background. You will be asked to provide a short sentence justification for each ability. There will be certain abilities that will be exclusive of other abilities including being a Godi, Seidr, Bearskin, Svinfylking, Ulfhednar, or Hrutar.
You can go ahead and start thinking about your character (and costume) before we release the full ruleset and character sheet, and open registrations. Character ability advancement will be at your discretion, (subject to GM approval), but is not a focus of the game.
