The X Society
A short campaign round around 2000-1, featuring James Malick, Alex Graves, Sarah Hill, Stuart Black and David Price. The campaign was run for a different mix of previous players plus some new ones.
The campaign began using an idea from Somewhere South of Midnight by Stephen Laws. Bright lights on the road cause the party to be partially possessed by spirits from space. These were the Guardians, who were in a battle against the Overlords, another, darker group of spirits from space. The Overlords were using a radio telescope to transfer the consciousnesses to earth and turning the staff into monsters.
The party were able to defeat the plans of the Overlords. The Guardians stayed with them though, guiding them on other adventures and helping them develop their psychic abilites. The Guardians had a more sinister agenda themselves, but the campaign ended before I was able to develop this much.
So apart from the Music of the Sphere adventure (the radio telescope story), there are no records of what other adventures this group played.
