Memory:Ratling dealer

Another ratling in the trading line. His home is the bottom of a very deep rift. With his dark grey cloak, he almost seems to be part of the shady dungeon where he likes to go about his business, so don't slay him by mistake --- you might need him! He knows about the relationship between supply and demand, and as he enjoys the trading monopoly for a vital commodity, his prices are far from moderate. But if you are very poor (or very clever), he might make a special offer and only ask the lowest possible price.
