domino7: “What would happen to someone who spends a year or more in the nevernever, eating nevernever food, breathing nevernever air, then returns to the real world? Do they get sick/die as all the ectoplasmic stuff in their bodies turns to goo, or does it metaphysically become one with them?”
Butcher: “They get sick and die. That’s why you shouldn’t eat Faerie Food. After, what is it, seven years or so, you’ve completely replaced the cells in your body with new cells. If they all come from faerie food, you just glorp to the floor. I think there might be some brain left.”

Nicolasmilioni: “How does a Faerie gain power? How would a weak goblin become like the Erlking? Or a weak gruff become like the eldest gruff?”
Butcher: “Time, effort, and will. Keep an eye on Toot-toot.”

Deusmalusest: “Is The Erlking a mantle in the same way as the other Fae titles? I know he’s referred to as Herne at one point in Cold Days, so that got me thinking, considering that he’s also (if I remember correctly) the Summer King.”
Butcher: ”There is no such thing as a Summer King in the Dresden Files faerie cosmology. Mab and Titania need a King like a fish needs a bicycle. There are a ton of independent rulers of the Wyld, though, much like the Erlking, who is a member of the Winter Court more or less as a sign of courtesy and respect. They will occasionally make alliances (and dalliances) with the great rulers of the Sidhe.”

EndlessKng: “If someone owes a being with a mantle a favor (say someone owed Lloyd a favor), and that mantle passes to someone before the favor was called in (to, say, a certain Chicago Wizard), does the person who receives the mantle get the favor? Also, if a unique denizen of Faerie akin to Cat Sith were to die, does it have a mantle that passes on? Would the next-eldest malk be able to get more powerful?”
Butcher: Depends of the nature of the mantle. Not all of them are all about obligation, the way the Faerie mantles are. But as far as Faerie mantles go, yes. If you owed Maeve a favor when Maeve was the Winter Lady, you don’t get out of your debt just because there’s a new Winter Lady in town. Molly is the one who is going to collect now. The mantle of Eldest is an important one in Faerie, and yes, it would pass on should its bearer perish.”
