Donnerach

Donnerach, known as Thunder-Dragon and Guardian of the East, is a major deity in several Southern pantheons. He is the God of Thunder and the God of Lightinings, reveared as mankind's great ally and tutor.

Accoding to Southern myths, he is the Dragon that taught mankind how to wield the power of thunder and lightning, as well as the one who constructed the magical barrier between Caemuth and Larthorn.

His counterpart in the Norscan culture is Dororm, although the two are portrayed as quite different deities. However his real counterpart was a Dragon called Nyscagos.
