The mercantile faerie leans on his long poling staff, the lantern dimming somewhat before he speaks. "I come on a mission of mercy today. I have a request from a young lad who was born lame of leg and struggled to get his apprenticeship with a furniture maker. This last winter, an accident claimed his other leg; I am looking for someone who would kindly trade me the use of one of their legs. The poor child is offering his youth in return for this kindly gift; he asks for only one, because it is all he needs to return to his harsh work."
Akakios has been commissioned to trade a boy's youth for the use of a leg(the right). Obviously, accepting this deal will make the bargainer lame in that leg. He would also accept a magical way for the boy to walk again - though it would have to be a magical item or an Arcane-Connection range ritual spell. He is unwilling to trade this for vis, as he is doing it on commission.
A Child's Youth: The boy's youth is represented by a leather bag sewn shut with something rattling around inside it. Wearing the bag around the neck for the bulk of the year will give the now-lame mortal two dice to roll on his aging at the next year, accepting the lower of the two - the child will accept the higher roll, and any associated aging crises. The child has 1 decrepitude point already, due to poor living conditions, and the benefit ends when the child dies. Opening the sewn-shut bag reveals three teeth dirty teeth, each worth a pawn of corpus vis, but ruins its faerie magic.
His extra stocks this year are quite fine, as he has a six strangely-cut rubies each worth a pawn of ignem vis; Two testicles from a Cretian bull each worth a pawn of creo vis; And an entire travelling chest of storm-soaked and shredded robes and dresses, amounting to nine auram vis. This last is supposedly from a Thessaly Witch, but the clothing is no longer an arcane connection to anyone except the chest they're in.
