Well the goblin leader would have assumed Deneve is an outcast drow, and tells her as much, offering an alliance. Basically Deneve would be his advisor (although it would have unclear how high she would rank compared to the other notable kobolds and goblins). Your first task would be to investigate the Hide Hills, to see if an alliance can be made with the trolls. Failing that the goblin leader wants them eliminated so that an attack can be launched on the Pirate Island. Would you leaving on this task (regardless of whether you intend to fulfil it) be a good starting point?<br/>Although this does raise the difficulty of what happens to rest of the PCs. Some could be left behind as collateral, which is convenient but would Rose and Deneve agree to that, even if the goblin leader insisted? This becomes even more of a problem if you do not intend to return.<br/>As for the ship, the goblin leader dodges any questions of whether or not it could be used to leave the island, as they worship the great sharks in the water they see no reason to do so.
