The Brilliant Star is the yellow shard of the ata'mal crystal. It was taken from Velen at the beginning of the orcs' rampage across Draenor. It calms the carrier's emotions, purifying them, allowing them clarity in their decisions. This especially affects casters, allowing a manipulation of the arcane and elemental magics rarely paralleled elsewhere. This was useful in the orcs' destruction of the draenic forces. Its current location is unknown.
