Jubal

Jubal Vedd is the younger brother of Gondel Vedd and a famous tempest. His fame stems from a battle where he slew a major force of Hathrim on his own.

''Odd note: there is a single reference to his name being "Tammel Vedd" at the beginning of A Plague of Giants, but this is the only reference to that name in the book and it very clearly seems to be a reference to the same brother that is, consistently later-on, referred to as "Jubal". Presumably "Tammel" was the originally intended name for this character.''
