A Crimson Cabalist
The Crimson Cabal were pyromancers who were successors of the first magi trained in Strom by the elves to fight in the Troll Wars
Hundreds of years ago, during the Troll Wars, Arathor had entered into an alliance with Quel'Thalas. The elves had taught one hundred humans how to wield magic. Those one hundred men had become fire magi; the Crimson Cabal. While many spellcasters had moved on to found Dalaran, Arathor never lost its original order of magi; its Crimson Cabal.
Tabard of the Crimson Cabal
The Crimson Cabal was isolationist and rarely interfered in any public affairs but were staunch defenders of Stromgarde and their faith, the Holy Light. They were lead by a council of three Lords of the Crimson Cabal. During the Great War the three leaders of the Crimson Cabal were Magus Lijou, Magus Azshard and Magus Elrich.
