The Warder's Relic are two ancient gauntlets acquired by the Resistance and later by Dredge, though it led to the admiral's death as he was not worthy to control the power of the dragon.
Only Warders can control the gauntlets. With them it is possible to summon the Elder Dragon and fire weapon attacks. Now the gauntlets are used by Imani.
