The Haffegul was an enormous deepstrider that roamed the Forgotten Sea in the mid 13th century.
Lore[]
The Haffegul is an endlessly ravenous beast of the Forgotten Sea, beholden only to a hunger that intensifies with each meal. To earn its allegiance, the Lilin Elder Morwith plied it with the survivors of her own voyage. The Haffegul followed where she sailed, devouring ships' crews whole and leaving the wrecks to Morwith's command.[1]
In-game[]
The Haffegul is a boss in Diablo Immortal, released with the Age of Falling Towers update. It is the final boss in the Dread Reaver dungeon.
