Lum (Hall of Doors)
The Lum is an object which appears in the Hall of Doors in Rayman 2. Unlike most Lums found throughout the Rayman series, this particular Lum cannot be collected. It is golden in colour and has neither eyes nor wings. Its only purpose it to travel through the Hall, moving from one Spiral Door to another. This is presumably to help the player tell which level they have selected; it is not clear exactly what purpose the Lum serves from Rayman's perspective. When a Spiral Door is touched by the Lum, it begins to spin and sparkle, and a hologram of something representative of that Door's level appears.
Murfy tells Rayman how to use the Lum; here it is seen at the centre of the Spiral Door leading to the Fairy Glade, with a representative Popolopoï hologram hovering above it.
The Lum follows Rayman, moving from one Spiral Door to another.
