Sentinel: Descendants in Time (2004)

Beni finds himself forced to enter the most dangerous tomb in a nearby tomb-field left behind by the long-gone Tastan civilization.

Outside the tomb, he desperately tries to persuade Doba to change his mind. He reminds the overbearing and stubborn crime lord that the Tastan tombs have little treasure in the usual sense and few easily removable artifacts.

Beni also says that the ancient Tastan technology is beyond the best minds of his day and inaccessible to modern scientists and souvenir hunters. He warns that even the great Ramirez was barely able to make it out of Tomb 35 with his life.
