Shak

Shak is a member of the Mountain-Folk and the best blacksmith in the Abyss.

When the Avatar first found him in Ultima Underworld I in his hidden workshop on the second level of the Abyss, Shak offered his services of repairing items for the right price in gold. He also told the Avatar about the fantastic sword Caliburn, the sword of Justice.

This proved to be important, as the Avatar later found Caliburn brokenin two and it took Shak's experience (and lots of money) to get the pieces back together into one, functional sword. Later he was most likely rescued by Garamon, when the volcano errupted.
