The entire premise of the game is a raid on another plane of existence (the 10th realm), early game you can raid caves, dungeons, and caverns with cultists, later game you get to raid fueling villages, castles, and forts. I don't know how you missed the raiding concept if you've played the game. PVP raiding could be cool, but that's already set up on public servers and has an RP aspect to it sometimes.
