Tooth and Claw is a gorgeous world of unspoilt wilderness and simple creatures living simple, if often brutal, lives. The world actively reshapes any new arrivals to suit. Regardless of who, or what, you were before you arrived, you are now a woodland creature, bereft of magical or technological enhancements.
It can be difficult to engage the locals in conversation (not least because several of them will want to eat you), but once you are over that hurdle, they will tell you that 'strangers' are not uncommon, and are widely regarded as lunatics and easy pickings. Further conversation will reveal that there are tales of 'a great brightness' off to the west, on the other side of a great river, and that it seems to have a great draw to strangers.
And so here you are, on the edge of a forest, on an alien world, in an alien form, with nothing but strange stories that might - and only might - point to a way home. What do you do?
