Ophidians (Ultima Online)

Ophidians are snake-like, swamp-dwelling creature that populate The Lost Lands, which appeared for the first time in Ultima Online: The Second Age. They look like some sort of hybrid between man and snake. They are sworn enemies to the Terathans.

Ophidians were meant to be included in the cancelled. See Ultima X Ophidian for details.
