Castle Rochelle

Castle Rochelle is Nemesis' castle and the final dungeon of Odyssey: The Legend of Nemesis. It was named in honor of Nemesis' lost lover, Rochelle.

First floor
The first floor contains Red's quarters, as well as rooms containing weapons, armor, and psionics and a small room resembling a chapel or classroom. The castle can be exited from here, but the only place that can be accessed from outside is the Tunnel to the Proving Grounds. The Glowing Key, which is required to access the fourth and fifth floors, is found in a trunk in Red's bedroom.

Second floor
The second floor's main feature is a menagerie containing specimens of almost every monster in the game. It also contains a room with a machine that presumably produces Ronan Minions, which is where the glowing mirror in Ronan's Tower leads.

Third floor
The third floor features a room containing various puzzle elements from elsewhere in the game, and an oddly-shaped chamber containing a glowing rune with no known effect.

Fourth floor
The northern half of this floor is a map of the Archipelago, which features the only walkable water tiles in the game. The other half contains a prison housing test subjects from every island except McTeague and a storeroom containing a wide variety of items.

Fifth floor
The fifth floor is Nemesis' private chambers. The southwest corner contains the access shaft leading to the sublevel.

Sublevel
The sublevel is a labyrinthine chamber containing the Staff.

East wing
The first three floors of the castle's east wing are composed of a series of puzzles, created as a test for Red's prospective replacement. This is where the protagonist arrives when using the N Staff, which is the only way to access it.
