Where there once was sand

In the middle of an endless desert, an old professor is giving his last efforts trying to discover what he've sought his whole life: the lost civilization of Mu. A life spent in the hunt of a myth, yet without any conclusive finding to support his theory that the continent is now buried under the sand. His funding has been cut and the camp site is now to be turned into a mining complex. As a sentient machine sent to prospect the surroundings for geological opportunities, will you try to empathize with him, will try to help him unveil what may lie beneath the sand, or will you just limit yourself to what you've been sent for? You may well be the help Dr. Willis had been expecting all this time...
