Use Brann's Communicator to contact Brann Bronzebeard and speak with him, then speak to Boktar Bloodfury at the Grom'arsh Crash-Site.
If you lose Brann's Communicator, speak with Moteha Windborn at the Grom'arsh Crash-Site.
What are you waiting for? The language barrier has been broken, thanks to Moteha. Contact Brann Bronzebeard and find out anything you can about where he's hiding and what he's chasing after.
Maybe we can still salvage something from this disaster.
