Sparrow: The only record of a Being ever dying is from a Nazi experiment. The record of everything they tested on the poor thing is buried in some archive somewhere, but you can find this much online: It was kept without a Master.

Nobody was allowed to visit it alone. If anybody tried to make a Contract with it, the order was to shoot them instantly.

Given what we’ve seen happen to a Being whose Master won’t take her into fights or give her a whole lot of orders . . .

. . . what would happen if a Being was forced to spend years on end with no Master at all?
