Noxum

Noxum is a spiny nixie who, during the time of Ultima IV, can be found in a pool behind Serpent's Hold.

Strangely for his kind, Noxum is friendly and will speak with The Stranger. He mentions that there are many ships at the bottom of the sea and that survivors would know where to search for them. Then he proceeded to ask if The Stranger had heard of the H.M.S. Cape and spoke of its magical wheel which would strengthen its hull.
