Description

 * The titanic watchers Tyr and Archaedas created this shield when their comrade, Loken, fell to corruption. They gave Truthguard to a vrykul champion who used it to expose Loken's treachery. When Tyr and his allies later stole the Discs of Norgannon and fled, the champion stayed behind and held off many of Loken's servants. A desperate Loken sent horrific monsters after Tyr, who fell in combat. In time the vrykul champion migrated to Stormheim in the Broken Isles, where the shield was eventually entombed in the Path of Kings.
