Can you take mine?
It's a Hardmode single-player planet like one in Caliborn's session.
You might find yourself quite lost within the land of STEEL AND SILICONE, an endless sprawling labyrinth of a land. Unlike most easy-going planets, this land is one large planetary sized MIKE TYSON SPHERE, a dyson sphere packing the punch of BOXING OGRES and RINGLORDS, guarding elevators, thousands of miles of stairs and hallways, paths and sky scrapers, and an endless dome made entirely of the planet's core, where you'll be spending most of your time navigating.
The consorts are SILICONE MUTANTS (think gears of war basically) that fight in tribal wars constantly with plasma-splatters and matter-shooters, you will have to carefully choose your alliances and engage in this never-ending STRIFE in order to survive the core of your planet. With a ticking clock to it's explosion, you must hurry to move the PRIME DETONATOR, a huge-ass bomb at center of your planet to the outside of it in order explode it and send it into a black hole at your sessions center. Failure to venture out before it's timer sets will explode it prematurely.
The planet is kind of like the core of derse basically but it's all dark obsidian sky scrapers, towers, stairs and paths, ect on the inside which is where the quest takes place. It's just a thick steel core shell on the outside with no real features.
