An Anomalous Shrine

My research team located a strange sanctum nearby. We were able to make out some writing on the outside of it--titan runes, to be exact--which we believe reference Aman'Thul the Highfather, leader of the titans, in several places. We tried to inspect more closely but must have triggered the sanctum's defenses. A massive sand amalgam blocked us off and we narrowly made it out alive. We aren't certain what it's protecting, but it must be important. Can you investigate?
