Arcane

The arcane are a race of merchants, found wherever there is potential trade in magical items. They appear as tall, lanky, blue giants with elongated faces and thin fingers, each finger having one more joint than is common in most humanoid life. The arcane dress in robes, although there are individuals who are found in heavier armor, a combination of chain links with patches of plate.
Nothing is known about the arcane's origins; they come and go as they please, and are found throughout the known worlds. When they travel, they do so on the ships and vehicles of other races. Finding such ships with arcane aboard is rare, and it is suspected that the arcane have another way of travelling over long distances.
Contacting the arcane is no trouble in most civilized areas: a few words spread through the local grapevine, through taverns, guilds, and barracks, are enough to bring one of these creatures to the surface. In game terms, there is a base 10% chance per day of finding an arcane, if PCs actively look for one; the chance increases or decreases depending on their location. Arcane never set up permanent magic shops.
