The Brethren of the Reborn Sun
Entry into this DM faction no longer requires an application, potential members merely need to inquire with a DM for membership and explain why your PC is suitable, and if we're convinced, we'll set you up.
Please, however, keep in mind there are still standards. If your PC will blow all the faction secrets or obviously undermine it, you will face consequences from its leadership.
Over the next few days/weeks, the Brethren will have a series of events. Some of these will be perma death for faction members and affiliated allies, however, the rewards will be considerable. There will will also be the possibility of failing utterly. I encourage everyone who is looking for a concept to join with a unique period of religious and secular conflict that the Brethren represents.
