The Grand Arcanes was a faction of both the Nawirrûs Covenant and the Quara'tun Covenant. They were purveyors of arcane lore, enchanters, and practitioners of the arcane. They are best known for the development and deployment of the Cubes of Arcane; devices that greatly expedited the process of creating new worlds.
Followers of 3-C contest the claim that the Cubes were a product of the Grand Arcanes. They say these wonders were salvaged from the Sea of Entropy, the works of some advanced civilization of the Lost Ages.
Two of the more notable members of this group were Arcana and Sehanine.
