Warlock

Warlocks are practitioners of Fel Magic, and in a lot of cases, Demonology, though have been seen to also commonly practice Alchemy, Tailoring, and more. As practitioners of more "Dark Magics" Warlocks are generally frowned upon by the better amount of the community, though some earn respect to the people, or some members of the community have been said to not frown upon this, whether they are a Warlock as-well or not.

Hiding of Practice
Whether due to the fact a Warlock may want secrecy about being one, to not be frowned upon, or to be caught if going against the law, Warlocks commonly practice in secreted areas, such as Catacombs under cathedrals or taverns, though it is considered extremely disrespectful against the Holy Light to practice under the sacred grounds of Cathedrals, thus some Warlocks do have courtesy of this, though others bluntly ignore it.

Grand Warlocks
A Grand Warlock is a Warlock whom has shown incredible skill above all others in the arts of Fel Magic, and is achieved by few. Notably this title has been achieved by the evil Gul'dan, but has also been achieved by a few others, such as Rossko Cauldella, and Turlias Moonweave, both extremely revered Warlocks.
