One of the great seven wyrms born of Midgardsormr.

He is said to have terrorized Coerthas since Ishgard's founding, spreading death and destruction for the past thousand years.

History speaks most notably of his clash with King Thordan I. Though the battle cost the lives of the king and many of his men, Nidhogg would not escape unscathed. The hero Haldrath plucked from his skull a trophy—a treasure simply known as "the Eye."

This relic of unimaginable power remains sealed deep within the vaults of Ishgard.
