There are few that still follow the steps of the Burning Legion or that were part of it and less that rp their char as a devoted of Sargeras or just someone that seeked power within the ranks of the Legion but this is the only community that I know that have warlocks that follow that path.
We usually do an event each week and a meeting each saturday, but at the moment rp is being halt until the next week, which doesn’t mean that others wont be up for it.
