Doloras

Doloras is the Zealan god of grief.

He was scheduled to appear in The Lost Vale, where the Elemental Titans had locked him together with his fellow gods Felicitar and Timyra into force fields. It obviously would have been the Avatar's job to free them to gain their help.

However, The Lost Vale was cancelled, and the only mention of Doloras was in a book about the old Zealan religion written by Yradan the Scholar. The book contained a fictitious claim that Doloras had a Torax head.
