Turbine has announced a new 12-man Raid:
Daring players will be drawn down into the depths of the Waterworks of Moria to investigate "strange happenings" there. Once you have unlocked the gate, it will take teamwork and strategy with eleven of your friends to defeat the corrupt creature within!
We have exclusively, thanks to Hellfanger again, some more information about this raid from Beta Book 7:
"They will be releasing a 12-man Pre-Watcher raid against the giant turtle Nornuan - 700k HP turtle. This raid rewards second ages, and so far some radiance pieces (non-set pieces, but still give +1 hope regardless). Basically, a transition raid into The Watcher raid".
