Three miles deep...
The sand started pouring into the crevasse at a rapid rate, with the tomb's walls beginning to lower further and futher until they were fully collapsed. The roaring of the sand was unsettling. Some sort of release mechanism must have triggered it. At the top of the ledge, was Orin, engaging hand to hand combat with a Malatak striking him inch by inch with his knives. The Malatak must have been a scout or assassin of some sort in wait for his demise. Orin stepped backwards and sweeped under him with his leg, dragging his body, and threw him over the edge.
Orin looked over. He saw the scout still hanging over the edge, but he could not believe who he saw once the mask fell off the Malatak's face. Finally he let go.
