[Note: Encounter C-3 The Pool of Life in deep in the woods and didn't really make any sense to me - a healing pool without any nearby encounters doesn't mean much in 4e with extended rests, so I moved it to a fountain adjacent to The Grotto, near where the sea devil was hiding controlling the drake... I also bumped it's power just a bit...]
Running down to the base of the mountain, heading directly for the amplfiying roars, they see a natural cave containing a fountain surrounded by several statues.

This chamber opened into a large cave-grotto - where a large ship was docked an under attack by the Sea Drake.
(Here's the grand table view of the action when it all starts...)
The party hasn't been noticed by the pirates who are focused on attacking the monster with bows and ballista. They don't see the sea drakes controller anywhere and assume he's in the water somewhere. So the investigate the fountain -and find that drinking from it restores two healing surges as well as restores an encounter power! They would use this during the coming battle as well.
The paladin examines the statutes (as she did back in the round room) and notices that one of them doesn't have any dust on it. The party looks closely, and this lizard-like creature statue is wearing a crown, apparently modeled after the coral one that controls the Sea Drake. They quickly conclude that this must be the stone-form of their quarry and attack, doing no damage. Since 3 party members were close, the statue chooses to come alive and execute it's close-burst attack! The battle is joined, and draws the attention of some of the pirates as well!
The sea drake, continues to take chunks out of The Raptor while battle continues.
Eventually, the controller is vanquished and a few moments later, freed from the crown's influence the sea drake gives up the attack..

The irregulars then take the fight to the docks - "Get those slaver scum!". There was much combat and intimidation. All of Bhet's crew were either killed, or jumped into the water and swam out of the grotto!
After securing the ship, The crew of the Even Keel arrived at the grotto, and everyone was able to sail home (after a brief trip back to visit with the Coyomi, and visiting one last time with Snake-Sister.)
Mission complete.
