Like "paws" are roughly on scale to feet, "stones" are roughly equivalent to pounds.
Regarding what attire the characters wear... most of the pictures of furries would seem to suggest that they don't worry much about foot wear (Puss in Boots being a noteable exception). I would imagine creatures in this world mostly prefer to keep their paws (both hands and feet) free, as many of the animals use their paws for their abilities in climbing, digging, jumping, stealth, and swimming. Tunics, shirts, trousers, belts, cloaks, hats, and armor though are all good though.
Character is starting to come together, just waiting on an answer to my PM Questions before I settle on Attribute Rolls, but I am slowly but surely developing the concept and description of my Otter Talespinner!
Currently Pondering a Back Story description of sorts!
There doesn't seem to be many (if any? I don't recall any) references to anything on the scale of dieties in Redwall lore either. For the most part in that setting, there are figures of legend, ie people of note from far off history, that are referenced in part of invocation of good luck or safe journey, or are seen in visions.
In general, it seems to be along the lines of smaller scale beings of note, like the founders of various places. I don't know if Ayrn's aiming for that sort of route with this setting, but I figured I'd put my two pinecones in with what I remember.
Because of the History that I am developing for Oltovian, he will probably refer to a benevolent diety he refers to as Provider of the Woods, which should fit quite nicely and can be incorporated from time to time in musings and of course his story-telling, along with what Reralae has referenced as 'figures of legend' lore!
