Princess & Conquest art/lore.
Those thick claws Kobolds carry were in fact developed to help them climb those tough thick trees in the forests they call home. Then after leaving the forests they made a shocking discovery: turns out having big tough and hard to break claws is useful for other things too! Of course, even after moving to the caves, the Kobolds haven't forgotten their roots. They're probably most in their natural element among the trees, climbing and scouring across branches. The Princess especially is a natural climber and looks right at home among the tree tops. She's probably a good scouter when travelling with the Knight, huh?
