[Miozeriux]

Hello guys, i was in Serpentshrine Cavern with my cousin, we managed to kill few boss but we were looking for Lady Vashjr, i know there has to be bridge control activation panel to find the way to Vashjr, but i walked around that raid for like an hour and coudnt find any way to get to Vashjr, anyone could confirm me that its all workin or could tell me where to find that bridge control? THanks very much!!
