Jy'eleria was a Dragon that dwelled in the Crystal Caverns in the extreme east foothills of the Forge Mountains . Attuned to Earth, Magic, and Spirit Ether, she was significantly powerful, and also animated golems from the crystals of the cavern as defenders.
Appearing as a Dragon covered in radiant gem-scales, she was successful in several efforts at posing as the avatar of the Lifegiver. She used this method both to gain access to and steal the Runestone of Fyrelight, as well as form a small cult dedicated to her amongst Delwynvale's halflings.
She was defeated in the Age of Knowledge by The Companions, seeking the Runestone of Fyrelight from her horde.
