This might be yet another case of me not noticing something that’s been in the game since day one, but I’ll post it anyway.
While wandering the depths of Rata Sum the other evening, I ran across a barely noticeable electronic percussion track playing near some NPC’s. These would be Krewe Leader Jerr “The Golem” and several other Asura /cheering him. He’s quite close to the Apprentice Waypoint, and you’ll only hear the music if you get next to his platform or right up on it with him and his friends.
I know these things are never accidental, so I assume there’s a story behind this. Google has not been helpful in this case, however. So I’m asking: what have we got here, an Asuran aerobics class?
