Voidcallers are a type of voidwalker that look to be draped in old, rotting cloth. Voidcallers are spell-casting voidwalkers. They carry over their draped shoulders two lanterns that bridge the realm of the living and the dead. These lanterns hang from a glowing crystal-like structure that strongly resembles parts of a naaru. Voidcallers' specific relationship with naaru is unclear; in exceedingly rare cases, the naaru are known to fall into a void state.
