Posted underground group for now, boat later today or tomorrow, Keegan two days from now.

Some things you can do:

-Convince Narivar to stand down and spit out his key. Need two people to succeed. 
-Disarm the two surviving Dunmers. You can try asking them or suprise them by force.
-Getting some payback on Hlaalu, who is trapped underneath rubbles.
-Loot the centurion.
-Go back out for fresh air and check on the wounded.
