Description
Given the artifacts you found on the altar, I would guess they were attempting to perform a Spiritbinding ritual.

Most of the texts involving Spiritbinding were locked away in the Tomb of Shadows. Perhaps we will find the answers we seek there.

Look for anything that might help us. You'll find the tomb on the first rise closest to the ritual altar.

Rewards
You will also receive:

Progress
Did you find anything in the Tomb of Shadows?

Completion
These tablets recount the history of the Mogu and the Zandalari alliance dating back to the time of the first Mogu emperor.

By the looks of things they have rekindled their alliance. But why now?
