Druna, actually, this guild is based off of the original guild "Gods of Olympus" from scapegaming (WoWScape). However, the server hit some major problems since then, and since then we have been split up a little bit. Now, we have the majority of our players on Scape and Legacy. I would guess the majority have moved to Legacy however. And yes, that would be the legion server.
The ones that still play on scape are loyal players and will likely stay there and Scape comes back to power (as likely it will).
Don't worry too much however. You're in a good guild, and both servers are fine and will be growing (both the guild and the server). I also know that Cassavir is arranging some pretty major things for Legacy. So you're in good hands with him.
Glad to have ya! Hope you enjoy GoO!
