I thought I'd mention that there is another what I'd consider to be major faction floating around in EfU, that due to recent IC events could use some increased membership.
It's essentially a double-faction, with PCs either being considered a Keeper (Druid or Druid multiclass) or Guardian (most classes accepted). It's obviously a nature-oriented group, which has a unique role in the dynamic of EfU.
Feel free to speak with me on IRC if you're interested, and feel free to apply as a Druid or Guardian even if you don't know much about the faction yet OOC (it's a secretive group, but any druidic or druidic-inclined PC should be able to fit in).
