Yep, Pax has guilds in both the Empire (Pax Imperius) and Republic (Pax Dominus). They originally started as separate divisions, but ever since server consolidations started they're pretty much intermeshed. Olmost everyone has characters on both sides.
Pax dabbles is in everythings, but we aren't hard core on any one aspect of the game. Certain people are hard core for certain parts of the game, but that's just personal preference. We PvP, we RP, we do silly events, we raid, we form up groups just to finish things that people need to finish.
Check us out. We're always looking for more members.
