Will of Remornia
Drops from Sire Denathrius. Remornia has been exposed to untold amounts of evil and sin, and will siphon power from any available source to fuel its desires. Magic type. Be careful walking around your Draenor garrison with this pet out - mine just murdered Pepe sitting in his tree!
Will of Remornia is a pet that drops from Sire Denathrius in Castle Nathria and can be obtained via LFR difficulty.
