Prison Island (Riven)
From MYSTlore
Prison Island is one of Riven's islands, where Catherine was held at one time.
By far the smallest of all five islands, it is covered by the remains of the Great Tree, and houses one small building, its prison.
A walkway connects it to a nearby firemarble dome. Otherwise, and uniquely, the island is entirely disconnected from the others; no trams or bridges can be used, making linking back and forth the only option of travelling to different islands.
Gehn used this island's prison as his personal office and for that reason he put a secret code on the elevator. AFter Gehn moved to Age 233, he decided to use it as a prison, to keep Catherine from helping the other Moiety. He saw her and the others as rebels, and as a threat to the system he had set up on Riven.
