Bring Falthir the Sightless a Primal Hakkari Aegis. You must also have a reputation equal to or greater than Revered with the Zandalar Tribe.
Falthir the Sightless is located on Yojamba Isle, Stranglethorn Vale.
My eyes failed me long ago, but I do not miss them. Even in a tribe such as ours - where one's vestments convey station and purpose - the most potent of garb exudes power that simple eyes cannot see. The prized tunic of the Zandalar madcap is no exception, exuding the raw power of chaos and madness that they are able to channel.
The Paragons of Power I need lie in Zul'Gurub; bring me what I seek, and I will reward you with your own legendary tunic... one befitting a weaver of madness.
