Protector

When the Theurgist Veras visited a village in Pagan, Trolls raided it, and began eating the children. One mother attempted to defend her child however, holding only a knitting needle and crying to Stratos for help. Hearing her plea, Stratos transformed the needle into a mighty weapon, and the Trolls were slaughtered. Veras took the weapon back to Argentrock Isle, where its properties were discovered: It would vastly increase its wielder's defensive ability; thus, it was given the name Protector. The weapon was safely put away on the island.

Having read the book with this story in Ultima VIII, the Avatar searched in the catacombs under Argentrock Isle, until the hero found a closed off building. After the hero opened it with a spell, the Protector was discovered within. It is unknown what happened to the weapon after the Avatar left Pagan for Britannia.

Trivia
