Sadly for Grampus, by the time he gets to the melee there is no place for him, as Rhod, Wiglaff, Maloof and Aldbane have sealed off the area around the door, and are bringing the force of four people to bear on a front of 3 goblins. A mostly indecisive skirmish results in Wiglaff slaying a second goblin, who gets replaced by another eager opponent.
The next round is a slaughter, as all four party members land their attacks, collectively butchering the three goblins outside the door.
The remaining 3 goblins inside the room slam the door shut!
