The next quest is that you have to go inside the mogu temple to get the divine bell but the nelfs are already there you chase them down avoiding all sorts of traps (its a pretty cool quest) you kill the sentinel commander but she just laughs and say the bell is now 'safely' inside darnassus
The quest after that you have to go all rogue and sneak into darnassus its very similar to the rogue legendary quest where you have to sneak inside ravenholdt
The belf mages help you into darnassus and give you a cloak to avoid detection
once you find the bell you attach a device and it gets ported out of darnassus by the belfs
The next quest is the purge of dalaran but its instanced and atm it just wont let you do the quest even though im exalted so im guessing that part is being tested in house
