Yes. Glad you like them so far.
Here are all the resources I have on them so far:http://brikwars.com/wiki/index.php?title=Zeitgeisteskrankheit
Overview of the faction.http://brikwars.com/wiki/index.php?title=Devoid_Sector
Faction's primary location and the shared Storyline there.http://brikwars.com/wiki/index.php?title=Ecto-115
The hatred element spawned by the Geist's Death Energies. Also spawned by other sources, so is usable outside of the Geist fiction.http://brikwars.com/wiki/index.php?title=Fetter
The items that bind ghosts to the corporeal world. Also not a Geist specific thing, usable by any spectral faction.http://www.brikwars.com/forums/viewtopic.php?f=31&t=11820
The LDD thread, which so far contains several microspace fighters, a cutter, and a corvette.
I'll be working on Devoid Sector Brikfic when I can get up the motivation to do it and the armory thread will evolve slowly over time, I hope. Thanks for your interest.
