Heart of Yavimaya
From MTG Salvation Wiki
The Heart of Yavimaya was the central magnigoth tree of the Yavimaya Forest. After Freyalise’s World Spell to end the Ice Age, the spirit of Yavimaya awoke and used its vines to kill sentient life: gorillas, elves, and humans. It was able to reanimate a dead elf through the use of its vines and green mana. Kaysa, Laina, Jaeuhl Carthalion, Jaya Ballard, Fyndhorn elves, and gorilla shamans cleansed the Heart.
