## Castle Area

- **Castle Gate**: A massive stone gatehouse. The drawbridge is down. Exits: north (Great Hall), south (Riverbank).

- **Great Hall**: A vast chamber with a high vaulted ceiling. Tapestries line the walls. Exits: south (Castle Gate), east (Kitchen).

- **Kitchen**: The smell of roasted meat lingers here. Large iron pots hang over a cold hearth. Exits: west (Great Hall).

## Castle Area Implementation

```python

castle_gate = Room("Castle Gate", "A massive stone gatehouse. The drawbridge is down.")

great_hall = Room("Great Hall", "A vast chamber with a high vaulted ceiling. Tapestries line the walls.")

kitchen = Room("Kitchen", "The smell of roasted meat lingers here. Large iron pots hang over a cold hearth.")

castle_gate.add_exit("north", great_hall)

castle_gate.add_exit("south", riverbank)

great_hall.add_exit("south", castle_gate)

great_hall.add_exit("east", kitchen)

kitchen.add_exit("west", great_hall)

# Connect Riverbank to Castle

riverbank.add_exit("north", castle_gate)
