Swapping ancillaries

[Rhedd]

It's dependant on the ancillary itself, and nothing else. Some can be traded, but most can't.

Other than a very few humans, like the tutor, most tradeable "ancillaries" are inanimate things like religious relics.

I wish more ancillary characters could be traded, but I suppose that would make them practically immortal, since you could trade them from one generation to the next, forever. That wouldn't be very realistic.
