I have considered the following and will allow them on Gwynddor if you plan to play(test) one of them:
- "Bulls" with patron deity Borgon: Dreamknight-Barbarians (Rage; for a Dwarf, Oega or Tauren/Giantkind)
- "Badgers" with patron deity Zamnait: Dreamknight Sorceror (Wild Magic; restricted to Schrat, Königstroll (Royal Gnome), Thellen Aentir races)
I would really only allow "badgers" as an extra for non-human nature magic creatures, so that they bring something special, which humans do not (and could not) add to the pool of options and skills. Humans, I feel, have enough of a natural bonus.
Any others you definitely want to play right now?
