Ganamrha is the guard of the Elven Village in King's Quest ZZT. When Alexander reached the village, Ganamrha greeted him, and told him of the how a golden candlestick had been stolen from the village guild hall by Ansil. He and the villagers wanted to chase after Ansil, but did not know where his hideout was. After Alexander discovered the hideout and recovered the golden candlestick he returned it to Ganamrha. The elf gave him some arrows to thank him. By the time of King's Quest ZZT 2, Dhurgei is has two guards.
