Kahan takes out the glowing golden box as others continue taking actions...
Leo hides in the shadows.
Borimer strikes with his sword. He is atop the back of the dragon and gets the blade in between the scales.
The dragon squeals a piercing cry and surfaces above the water with Borimer on its back. But as most dragons, it is highly intelligent. Borimer finds the dragon turning sideways and launching upward to smash Borimer into the ceiling and stalactites.
Borimer jumps out of the way just in time.
Tahldar is casting.
Shae successfully evades the dragon as it is distracted.
The heat from the previous spell is dissipating the fog, clearing your view of the entire room.
Borimer has just landed in the spot marked with an X (in the northeast), which is a perch about 10 feet above water that has green vegetation. The X at the bottom is where the white haired man came from.
Tahldar finishes his spell, but nothing seems to happen.
Kahan cannot find any way to open the gold box. However, it catches the dragon's attention. The dragon's wounds from Borimer heal almost immediately.
The dragon is now jumping into the raised center area (which is about 1 foot below the water level). The dragon is far too heavy to be swept away by the current there, but it is leveling its gaze at Kahan.
"Give that to me," it says, rearing back its head.
