Nythendra

Nythendra was once a member of the Green Dragonflight charged with guarding the world tree, Shaladrassil. When Xavius' corruption of the Nightmare consumed Shaladrassil, it consumed the sleeping guardian as well. Nythendra is now nothing more than a skeletal version of herself, swarming in pestilence, ready to devour anyone or anything foolish enough to enter her lair.
