ALLIANCE EU

Just adding this as been getting a ton of requests from people only to realise they are horde. I know letters are hard Hordeys, but the [A] in the title is for Alliance - you’ll have to wait for 9.0 I guess 
As the title says, Prima Mythica is a community started by a very small group of friends that run M+ keys together with the emphasis purely on fun and just getting it done.
We are firmly anti RIO. Your score means nothing to us. Are you willing to learn? Help others regardless of a low key or low knowledge/skill? Great, that’s the attitude we’re trying to foster. If the key gets done, awesome, but if not, oh well, we’ll get it next time.
We also have a Guild Discord that people can use if people want to (no requirements to though) help with communication in mid/higher keys, or just to come chat it up. Warning though, our small group are broad minded, but silly, adults.
Any of this sound like your cup of tea, we’d love to see you help us build a quality community to eventually get stuff done.
