Bearfolk? Perhaps something like hibernation? Sleeping at least 2 quarter days up to a week without having to eat or drink for a WP/day. Maybe they can spend an extra WP to not need a fire going during camp in winter conditions? Also, for the hibernation talent to be fun in summer time and south of the Bitter Reaches, a character in hibernation might be able to heal critical injuries, much like the elf kin talent inner peace...? Quite boring to have a similar effect as other kin but it would be fun to have something in line with such a characteristic trait as the hibernation of bears. Maybe I'll have a second thought about this...
I had tried to think of something along those lines, but with Sleep healing lost STR anyway I wasn't sure how much use it would be.. But, if it were to heal Critical injuries faster than usual, then it might be a good thematic ability.
Also, hibernating to negate the need for food & water would be good.
