Shadows of the Loa
Shadows of the Loa is a lore object found at [36.3, 70.4] inside one of the Harbingers of the Loa tents in central Za'Tual on the southern side of the Isle of Thunder. Interacting with the lore object is one of the requirements of the Pandaria exploration achievement 
[The Zandalari Prophecy].
The Zandalari worship "loa," powerful spirits who have been a part of the world predating even the titans. Countless loa exist, most weak, but some very powerful. Most are shapeless, whereas others have animal or creature forms.
Zandalari families often worship their own family loas, cities usually have their own civic deities, and the greatest loa are worshiped by the nation as a whole. Powerful, enlightened Zandalari can become loas upon their death - or so it is believed.
These spirits are central to the Zandalari worldview: so say the loa, so go the Zandalari.
