Entry to the Nursery is through a small cave in a mountainside. The cave meanders a short distance before it dead ends at a spillway for the river. Water under pressure flows from a manmade nozzle in the cave wall and arcs toward an opening in the cave floor. Water striking the wall is aerated and then falls into the hole below, much like a heavy rain. Within the hole is a fine grate that captures debris from the river. A set of stairs surrounding the hole leads down to yet another secure door.
The hole contains the filtration plant for the river. Debris captured by the grate is collected by crab-like scurry robots. The debris is then separated into organic and non-organic piles and taken to grinders where it is recycled. The water falls into a natural underground cavern where it is filtered through the water table. Finally, the water empties into yet another reservoir where it is pumped to the surface to replenish the river at its source. The filtration plant is powered by the geothermal power plant beneath the Nursery. However, in case of emergencies, the plant has a trio of hydro-electric generators for back up.
The filtration plant is overseen from a nearby control center. Here small contingents of robot wardens carefully watch the entire process. Most of these robots are simple maintenance droids capable of making the necessary decisions to keep the plant functional. However, the plant supervisor is a more sophisticated model capable of making command decisions independent of the main computer of the Nursery. He also has a small contingent of security robots armed with stun weapons at his disposal.
- Gain entry to the Nursery - the player must get by the locked security door in the spillway. This can be accomplished several ways.
