The Arcane Brotherhood was a wizard's guild that operated out of The Host Tower of the Arcane in Luskan. It was ostensibly a trade guild for training wizards and promoting trade; however, it was later uncovered to be a cabal of mages who secretly controlled Luskan and sought to establish political and economic control of The North. The Brotherhood effectively became defunct when its leader, Arklem Greeth, destroyed The Host Tower of the Arcane and killed all members.
