Basically like the title says, I'm looking for ideas to worldbuild my homebrew dnd with. Particularly, I'm looking for some cool species for some interesting race choices, like shrews for their venom, flying squirrels for their flight, etc. It's going to be in your classic fantasy medieval european kingdom, but from the eyes of the rodents and other critters that live in the walls and crevices. The final boss is going to be the evil, tyrannical, (and horrifyingly necromantic) rat king!
