The party reach the black octahedron in the middle of the lake and disembark. The sides are stepped enabling them to reach the entrance half way up with ease. Rather than a doorway, there is just a perfect pitch-black hole cut into the stone - magical darkness that even the Drow cannot see through. On entering, they find themselves in a well-lit corridor of sandy-coloured stone, with bright green vines growing through gaps between the bricks. The air is fresh and the plants lightly scented. A sense of health, wellbeing and relaxation penetrates the area.
As the Warlord starts to pull a brick from the wall to see what's behind it, the rest of the party wander down the corridor, only to hear an ominous thud behind them. A large stone boulder had dropped from the ceiling behind them and starts to roll slowly down the corridor towards them. Despite his best efforts, the Warlord fails to pull the stone he's working on out in time to jam it in the way,and he's flattened by the boulder. Only Chuck runs ahead to try and outpace the rolling stone; all the others are knocked down by its relentless movement. After picking themselves up, the Warlord simply continues his excavation of the wall and Mouse and the Drow investigate where the boulder came from, after failing to stop it with the Drow's spells. Chuck runs straight for the end of the corridor, just staying ahead of the rolling boulder and makes it through the door there before it crashes into the wall. The boulder then falls as the floor opens up underneath it, leaving a pit before the door on the corridor side.
On the other side is a dusty, grey, large room with an aura of solemnity and contemplation. A statue stands at one end and a large circular mosaic occupies much of the floor. As Chuck wanders forward to investigate it, the Warlord finally breaks through the wall he was working on and emerges in the same room Chuck is in. Only temporarily confused by the geometry of this place, the rest of the party take this route to avoid the gaping hole left by the boulder. They decipher the inscription on the statue and deduce that the mosaic is in fact a puzzle they need to solve to find a way out. They do this easily enough, and the whole completed picture suddenly starts to descend. Beneath appears to be icy cavern. The Warlord flies down -
- and finds himself flying up into a large ice cave, with several devils standing menacingly around. The rest of the party jump through, landing awkwardly near the hole in the floor, momentarily disorientated by the change of gravity's direction. A fight soon starts, and with some teleporting, some fire and a devil oscillating up and down through the hole for a while, the party are victorious. Above a ledge, embedded into the wall, is the stone tablet they were sent to look for. They gather around it.
