The quest giver, Vendel the Armorsmith is random spawn found at the beginning of the zone Watch Tower Level 2. Watch Tower itself, is a random spawn. Prior to patch 1.05 it could be found on the Western edge of the Northern Highlands. After patch 1.05, it is now found in the Southern Highlands.
"This scabbard is a rare treasure. Its inscription reads, "Talic the Defender," in archaic lettering. He was one of the ancients who guarded Mount Arreat until the shattering of the Worldstone, a true warrior who gave his life to spare the world from the dark fate it has fallen to now."
