The Arcane are a mysterious and ancient race of blue-skinned humanoids. They stand about 12 feet tall and have long fingers, each with one more joint than the fingers of most other humanoids. Each Arcane is apparently in constant telepathic contact with all other members of the species.
They are the apparent creators of most spelljamming helms and appear to have made it their mission to sell them to as many customers as possible. They are completely unconcerned with questions of morality and politics, dealing with just about any race or faction. The only exception seems to be the neogi, whom they contact only through intermediaries.
Very little is known about the Arcane, including where they came from, where they live, how they came to be the masters of spelljamming helms, why they are so keen on selling the helms, or what they do with their profits.
