Platform One
Platform One was an observation space station designed as an observation deck for various events. It was an Alpha Class space station, meaning it was 'top of the range'.
The space station was controlled by a computer, Control, which in turn was controlled by "the corporation". In 5,000,000,000 it was orbiting Earth when some of the richest and most powerful people in the universe gathered on it to witness the destruction of the planet by the expanding Sun. It was moved between different artistic events.
Platform One was capable of berthing several shuttles. It used Sun Filters to shield it from the heat of the Sun and a force field to protect it from the exploding Earth. The use of teleportation was forbidden on the platform under the Peace Treaty 5.4/cup/16. Weapons and religion were also forbidden on the platform.
It was staffed by the Steward and a large maintenance staff. The staff included plumbers to look after the air ducts, including Raffalo. The shafts also carried hot water, could be blocked and — depending on the area of the blockage — a suite could be left without hot water.
It had a suite called the Manchester Suite.
