MAIN QUEST HELP!! Somebody! Please!!

[Novelis]

Hi there
I have been playing for a while now, and have just finished the two quests from the sanctum "Team Spirit" and "Critical Discharge". The problem is I now have NOTHING to do! The woman told me to speak to Melvin or that other guy again but they just tell me there is nothing to do at the moment. I have done all the bounty missions and I'm a bit sick of randomly raiding caves waiting for an update to the main story. Can anyone help me out?!
Thanks in advance!

Go into the Main Building, use the teleporter plate and speak to Merzul.
