Title of Event: Cult Station 13
Pretense: Depends on how official the cult is on station, might be announced.
Equipment Necessary: Just normal cultist loadout.
Plot: Somehow, a good part/every protected member of the station were cultists of the silent one (Cult of Mortality), including the chaplain. As the Grim Reaper will get the people onboard the station soon enough, seeing the deathrate on the station, the cult has one objective/orders to NOT kill, only to spread. The cultists need to convert the station, people can submit to this, of course, and fortify the station, as a whoole station full of cultists likely is a target for some factions not wanting the cult to spread that much.
Prize for Completion: Not directly, but as the cult station would involve basically everyone, people might just get to know how to cult with the new gear.
Custom Sprites/OGG's: Not needed, maybe some spooky music to fit the cultstation.
It might be a bit like the force borging event, this time only with culting instead of borging, people not wanting to join there, or it is a bit more like a declaration of war, just with more preperation time, and fancy defences, like pylons to heal, invisible walls, teleportation, cult equipment, depending on how the cult does work together. You might be also able to remove the cultist hud, so you would basically have "traitors", which aren't cultists, and might try to get the drop on culties to deconvert and spread. I think there would be quite some possibilities to direct them.
