Planet Thoth

There once was a planet called Thoth that was used to imprison the souls of angry alien gods. Their souls were contained in pyramids made from a combination of obsidian, sandstone, and diamond. This combination of minerals kept even the strongest of the gods from escaping. Overtime, the atmosphere of the planet began to thin, allowing space debris to crash onto the planets surface, destroying the pyramids and freeing the souls of angry alien gods. They now seek to incarnate as entities of destruction, in order to unleash their wrath on the galaxy after eons of imprisonment.
    "Where are we?" asked Robert.
    "I don't know, the calibration system is down and we are almost out of fuel." replied Seria.
    "I wish that we had never robbed that grave on Ra." Robert said with a sigh.
    "Well we would have never met if we never went and you are the best intergalactic grave  robbing companion I have ever had the pleasure of working with." Serria said with a grin.
A few moments of silence pass before Robert spots something that looks like a planet in the distance, they deicide to land on the planet in search of resources to refuel their ship. The sand compresses underneath the weight of the boots of their space suits and they spot an obelisk that eerily looms in the distance. Perhaps there would be resources to refuel their ship some where within. As they reach the entrance of the obelisk a harsh desert wind blows them backwards onto the ground, the wind carries rocks that destroy their space suites and buries them in sand. The same sand that used to make up the pyramids that imprisoned the souls of angry alien gods. Like the gods, Robert and Serria's souls are now imprisoned for the rest of the planets life time.
