I agree, I've been mulling over this and one I kinda like is "Reason" as it pertains to both logic and existential questions, as wells as functions as sort of pair with Whimsy (or something akin to intuitive knowledge or randomness).
Reason also fits with the "survival" focus of the shard; it has formerly drawn the conclusion (reasoned) that the best course of action is to hide, but realised that it now may not be the wisest thing.
