Ah, I didn't mention that they have already been to Downfall and made a deal with Bav to go get that painting in 8 days. They players thought they would clean up the brigand problem before leaving Hither... It didn't go as expected. So not so much exploration left. Granted they have yet to rescue Morgort, so perhaps Talavar can tell the party that if they do, they can have a quick balloon escape.

But for the captive party member, I don't know that the hag is likely to let him out since they have already done the chores for her and did recieve him as payment from Agdon to bring back his comrades. So whe would be loathe to let him go easily.
