I have just raided Oryx's castle with a whole group of players, few died in the progress but we got through. MANY died against Oryx himself but we killed him and he left behind the entrance to the wine cellar, Only one person in our group had the key to the portal. but just before he was about to use it on the portal, it disappears. quite disappointing but the raid was damn fun.
I also ranked up to rank 2 as a wizard.
