The Riftguard

After the War of the Calamities that plagued the continent of Alari, The Dragon Priests, Arentis and Amethyst, deemed it necessary to create a faction to help protect the rifts that sporadically open between the Material Plane and the Inner Elemental Planes. This faction would be heralded as the RiftGuard, a group of Elite Fighters who learned how to harness the unstable elemental powers around the Rifts and channel them into combat. Their purpose is to protect the Rifts from those who wish to use them for immoral gains, and to ensure nothing makes it out from them, into the Material Plane.
