Can anyone point me towards some printed material that will help me create:
(1) Several bipedal caribou characters? (Deer / Moose / Elk-men would work fine).
(2) A bipedal polarbear character? (Any kind of bear-man would work fine)
Optimally, this would be a template in an existing pathfinder bestiary, or from an existing Adventure Path (since I own them all). If not, anything available on the PFSRD would also help.
For the cervids, you've got:
The god Erastil (God of Family, farming, hunting, trade)
The Empyreal Lord Cernunnos (God of Fertility, seasons, wild animals)
Cervinal Agathion (Deer-taur angels)
Toshigami Kami (well, it's a person with antlers...)
Wendigo (creapy canibal monster)
For the Ursids, you've got:
While there aren't any specifically called out, having other Agathians in either role would also make sense.
