The Loa of the Darkspear - Kevo ya Siti and Lukou

Players experiencing the Troll Heritage Armor questline were introduced to two new Loa — Kevo ya Siti, Loa of Cunning, and Lukou, Loa of Regeneration. These old friends and allies were long forgotten by the Darkspear, and through the course of the quest we renew our bond with the two powerful Loa — but who are they?

No references of this Loa were found among lore spread throughout Azeroth, but thankfully, many of the NPCs we encounter through the journey to find the Darkspear's lost Loa were more than happy to share what they knew about the stealthy Loa.

When we first encounter Kevo ya Siti, we find him stalking Hakkari priests in the ruins of Zul'Gurub. Jani, our Loa guide at the time, gave us this clue in the search:

As we continue, we learn more about the powers Kevo ya Siti possesses, including the ability to travel through shadows, imbue shadow energy into blades, and to allow others to become incorporeal in the shadows with him. The majority of other information we have on this Loa,
