The little demon that revives you every time you die in The Messenger is a bit of a git. It’s an often quoted idiom made famous (but not originated by) Benjamin Franklin, that “…in this world, nothing can be said to be certain, except death and taxes”. Quarble is both of these things. When he first appears, he gleefully informs you that every time you perish, he will take all of the gems you collect until his services have been paid for. He’s forever hiding in the background, waiting for you to slip up, so he can note your debt in his little ledger.
