1961. Professor Dimarx is an archaeologist who thinks he made the discovery of the century on his planet, Terra, on the forbidden continent. For posterity, he is followed by his long-time partner and friend, Gramuel Solus, who is in charge of filming this great event. On arriving at the ruins, they discover a chasm with stairs carved into the rock. Here and there, strange black crystals seem to indicate ancient volcanic activity. Dimarx is elated by his discovery, and descends into the depths of the earth without precautions, as if called by an unknown force to discover the first Black Cube in the modern history of Terra.
Free prequel of sorts to other Black Cube adventures, made as part of Adventure Jam 2018.
