The Sinister Six
Ath-Cullen, the Deathbow, is a legendary longbow owned by The Namer, currently in the possession of Kael Varda. The bow appears to be made of human bones, held together by twisted black roots that appear to have grown into the shape of a composite longbow naturally. The bow is said to have the power to strike its target dead, in addition to the power of infusing arrows with a horrible power that causes them to leave behind gaping wounds.
After a harrowing ritual which involved his death and resurrection, Kael appears to have unlocked additional powers within the bow, including the ability to see in darkness and inflict deadly wounds on command. The bow many have additional, as-yet undiscovered powers as well.
