Soon every solar system was living in fear. It seemed the invasion forces were growing, getting stronger as they landed on world after world, dispersing throughout every country on every continent of that world – or found the most desirable parts of the ocean floor on the water-worlds, planted their signs and sped off in their ships to conqueror the next planet, the next solar system, the next quadrant and the next galaxy.
Soon, it seemed the entire universe was living in fear, all fearing an invasion from the dread Estate Agents of Earth! Forced to leave their home planet by an economic downturn that seemed as though it would never end, the vast armies of estate agents took to their spaceships and set out to boldly find desirable residences where no estate agent had found before.
The galactic federation found they and their armies were outnumbered, out-gunned and outmanoeuvred by the swarms of estate agents that would pour from the invasion fleets to snap up every desirable residence on a planet, and then leave the devastated planet festooned with Estate Agent signs and slowly suffocating under the huge quantities of property description leaflets produced by each invasion force.
Some worlds tried pretending they were out, or had no properties up for sale. The councils controlling the floating cities of Handrash 12 even revoked all property rights and held all land and housing - on their floating islands high up in the sky - in common ownership of the people, but the canny estate agents staged a revolution, showing the citizens just how much their residence was worth on the intergalactic property-price websites and soon everyone on Handrash 12 was a property owner looking to sell as the bodies of the local councillors were pushed off over the edges of the floating cities into the Endless Seas, far below.
It seemed that no-one or nothing could stop the fearsome Estate Agents of Earth and their plans to put the entire universe up for sale... or rent.
