My original plan for November was a lot busier, but new employment has made me no longer have as much free time. So instead of creating a plethora of faerie creatures, I'm bringing in my favorite vis source of my home game: Akakios the Boatman.
Akakios brings a few things to trade: Faerie items, sometimes Magical items, vis, and legends. The vis is always tained faerie, though the form may once have been Magical. The magical items he trades from a magus will often develop a quick of faerie nature by the time he trades it away.
He takes a few things in trade for his wares: He prefers to trade in bargains and ephemerals, stealing away something appropriate from the customer themselves; he also is willing to trade for a magical item, valuing them as the vis expended the crafting (which he can tell by examining them); and he sometimes settles for trading raw vis for his wares.
If you wish mechanics for his bargains, he values each item at a certain vis value (example 8 vis). A Presence + bargain (faerie deals) roll against ease factor 12 will raise the perceived value of the mortal's trade by 2 pawns of vis. If the bargainer is trading an item they themselves crafted, it is valued at +2 pawns. Incredibly appropriate story-bound trades can also give a perceived value. He has also been known to accept arcane connections at 1-2 pawns of vis, though few people are willing to trade such to him, since he is known to deal with other magi.
Mariel the Merinita is trying to trade for a Rod of Awsomeness, which Akakios secretly values at 9 vis. His initial asking cost is all of Mariel's hair, because he knows Mariel is vain. She denies this, and begins bargaining. Despite her skill in bargaining and her beauty, she fails her bargain roll, but she is offering a Crown of Beautification, which she made but no longer needs. She spent 6 pawns of vis on it, but it is an appropriate comparison, so Akakios values hers at 8. They finally agree on the crown and a single pawn of Terram vis, since Akakios doesn't have any terram in stock.
