The Fortress of Flares within the Wailing Mountains lays abandoned for years, but it has not always been like that. The sealed temple was the place of meditation and great wisdom for the Bonds of the Guardian Flame, where the warrior poet Xin initiated the members of the group in a series of mantras and meditations designed to prepare the apprentices for the dangers lying beyond the walls. However, his courage brought him his death, conspired by those who were afraid of the growing power of the Guardians. As soon as their master died, his descendants spread across the world. The Burning Celestial was one of the last apprentices of the master, and one of the wisest. He cast the Fortress of Flares upon himself and reignited the pyre ash. The new creature is Ember Spirit, the image of Xin in flames, always ready to spread the fire of knowing upon those seeking to be wiser.
