This bloody quest has bugged out on another character. This time I have abandoned and restarted it but still broken.
This time I spoke to Razum-Dar and he's run over to where Captain Karinith should appear and spoken his lines, but the Captain isn't there and so I have no way to talk to her as he instructs me.
This means the main quest in this entire zone is screwed. Ticket raised, no hope of every getting it dealt with.
