Delta Green: Black Gold
A 'one-shot' scenario for Delta Green: The Roleplaying Game. The Mayans knew that under air is earth¸ under earth is water¸ and under water is fire. Since then¸ we've learned about the void above the air-- and we're awfully pleased with ourselves. But we never talk about the void beneath the Earth¸ or the mysteries that float therein. The Mayans disappeared overnight¸ and Doctor Ignacio Levanti believed that he held the key to that ancient mystery. That is¸ until his disappearance just forty eight hours ago. Now¸ an even bigger threat has emerged¸ and it is aware of the futile existence of humanity. If Delta Green can't contain this threat¸ then the Mayans might not be the only ones who vanish overnight...
