Tomas rushes down the corridor, turns a corner and passes through an iris valve into a massive room. The instant reaction is one of relief as the familiar shape of a fusion reactor looms before him, and he takes in the welcome sounds of an engineering room. But looking and listening closer, things don't seem quite so good. The sounds the reactor is making tell Tomas tell that it is running, but at nowhere near peak efficiency. His eyes are first drawn a few meters in front of him, where the contents of a tool chest lie sprawled across the floor. The chest itself is overturned, apparently having fallen of off the shelf that's right near it.
Then he notices the dust. It covers the floor here, even thicker than in the airlock. There is a layer of it on the tool chest, and even the sprawled tools. Tomas sees that some of the tools are missing - there are hand and foot prints in the dust near the tools, and outlines in the dust where tools had bee before being picked up. Looking back, Tomas can see foot prints in the dust leading to this spot from the door, and he wonder how he didn't see them as he came in. He sees the footprints lead away from the tools, through the swirls and little piles of dust that have been formed by the currents of the power plant's fans, across the huge room, towards what Tomas recognizes as Life Support.
There is a ladder next to the unit, and Tomas can see a large piece of metal sticking out the system at an angle no self-respecting engineer would create on purpose. Whether there is more physical damage, Tomas simply can't tell yet, and for the moment, he doesn't even think about it. Beneath the ladder is a huge, almost meter-high pile of the white stuff, and just in front of the ladder, lying face up on the floor, is someone in a vac suit.
