The Astral Hall (Japanese: 回想の部屋 Room of Reminiscence) is one of the many rooms in Luigi's Mansion. It is found in Area Three.
In Luigi's Mansion, the room is empty until Luigi lights the candles in the center of the room with his Fire Element. Once the candles are lit, Luigi can enter the center of the room for an event to occur: the candle flames turn purple and suddenly extinguish while the door leading to the Observatory appears with a seal over it. Luigi is then ambushed by ghosts, who he must defeat to turn on the lights and unseal the door to the Observatory.
The Astral Hall contains two drawers on either side of the room. In the center are five candelabra. If Luigi leaves the room after clearing it, the candles will be lit, but extinguishing them is impossible, even with the Water Element. A large crystal chandelier hangs in the middle of the candles.
