Gart

From Tardis Wiki, the free Doctor Who reference

Gart was a warrior who served under King Erak. He and his son Sherak overthrew Erak, though he allowed Sherak to take sole credit and become king.

Five years later, Sherak planned to explore the dark side of Mount Megeshra. Gart thought this idea was suicide, and when Sherak refused to listen, he left forever. (PROSE: Legacy)
