Hreth

A mortal woman who was the lover of Erol, the son of Haltan in the Old World, before the coming of the Ice and the fall of civilisation.

Hreth betrayed Erol, and layed evidence for her crimes that pointed at Erol's mother, Enrith. Erol only found out the truth after he had slain his own mother

Hreth was the daughter of the god Pel and the giantess Gruaga. Whether she is the same as the goddess Hreth is not known, but similarities between the two lead many to believe that she was.
