Please, ONE last try... did you rattle at Moreena's sleeping room door upstairs? I just tried your approach - I could run up and down countless times without success - then I clicked on her door upstairs and approached those guys => cut scene came.
Could you please, try this and report? <img src="/ubbthreads/images/graemlins/puppyeyes.gif" alt="" />
You can't continue the game... you need this fragment to get teleported back... The Necro quests are part of the main plot. You talked to Moreena and used all speech options, right?
