A Purple Lum is one of the many types of Lums that are found in the Glade of Dreams. These lums assure the cohesion of the world; without them, nothing would be solid or visible. Unlike the other Lums, this kind is shaped like a ring; rather than being collectible, they can be grabbed and used as hook by Rayman, so that he may cross large areas without touching the ground. Like Super Yellow Lums, Purple Lums have eyes.
In the games
Rayman 2: The Great Escape is the first game in which Purple Lums are names. In this game, Rayman gains the ability to swing from Purple Lums by absorbing a Silver Lum which was granted to him by Ly, after he freed her from her prison in the Fairy Glade.
In the original Rayman game, objects known as flying rings appeared. These rings are essentially this game's version of Purple Lums; the function in the exact same way, and appear very similar (but Purple Lums' wings are insectile, while flying rings' wings are more bird-like). This game also features evil flying rings; these are ugly, red versions which sink when grabbed, often putting Rayman in danger. Rayman must receive a Silver Lum from Betilla the Fairy in order to use flying rings.
Purple Lums also appear in Rayman M, where all of the characters can use them. They lack eyes in this game.
In the Game Boy Advance adaptation of Rayman 3, Purple Lums look very different from their previous appearances. They are larger, and while they lack eyes and wings, they now wear metal crowns.
In the Game Boy Advance version of Rayman Raving Rabbids, Purple Lums reappear, and look very similar to how they appeared in the Game Boy Advance version of Rayman 3. They now have a greyish colour.
In the Game Boy Color versions of Rayman 1 and Rayman 2, the Purple Lums move around freely in one location, ready for Rayman to grab onto them. There is one grabbing ring that looks red and black. It goes up and down. When Rayman grabs onto, it goes and stays up. When he lets go, it goes down. It can hurt Rayman and is located in Fiery Depths and Dark Legacy.
In the Nintendo DS version of Rayman Raving Rabbids, a lot later in the game you can find purple lums.
