Maegara

Maegara is an ancient entity made of flame. She was trapped in an iron flask, which the drow brought to the fire giants of Ironslag. Maegara was emptied out of the flask and placed in the magical forge in Ironslag. Diath used the flask to draw her out of the forge, and then freed her during an attempt to free dwarven slaves. Maegara's burning aura instantly killed all of the dwarves. As the Wafflecrew fled the mountain, Maegara was free, and reduced Ironslag to smoke and rubble.
