Lum (UbiArt games)
Lums (pronounced “Looms,” like ilLUMination, and not Lums, for dumb) are beings of pure energy possessed of a mindbogglingly sunny disposition. They are an important source of magical energy in the Glade of Dreams, making Lums Racing a popular Gladewide sport. The competition pits up to four players against each other in crazy crosscountry competitions to collect Lums. Anything goes in this wild race, or as we say around here, no smack is too packed. While all players go home winners, only one takes the prize: the player who nabs the most naphappy Lums, of course! No holds barred!—Official site, Rayman Origins
Lums can be quite illuminating, for those who know how to use their energy...
Lums are beings of pure energy who frequently appear in the Rayman series.
The Lums in Rayman Origins do not fit into the system of colours used for the Lums in the other games. Each Lum in Origins can alternate between yellow and red, but they do not have the same effects or appearances as Yellow Lums or Red Lums. Due to several glitches causing Lum-yielding objects to reappear indefinitely, the number of Lums in Origins is probably unlimited. However, considering the limit of 999 Lums per level, the known maximum in the whole game is over 23000; the amount of 999 Lums is displayed on the level-end screen even if the player has collected more. The Tings in the original Rayman are also in an unlimited number; however, Rayman 2: The Great Escape makes it clear that there are only 1,000 Yellow Lums in existence, and they are currently contained in the Heart of the World at the time of Origins. The Lums that appear in Rayman Origins are clearly sentient creatures, and have arms, legs, wings, eyes and mouths; in the other games, most Lums are simply orbs of energy with wings.
In Rayman Origins, the player often comes across large, crowned Lums called Lum Kings. Collecting a Lum King causes all the Lums in the area to sing and dance for a few seconds, while their colour changes from its usual yellow to red. While in this state, each Lum is worth two. Lums can be found floating freely or hidden inside nenuphars and Bulb-o-Lums. They can also be gained by bubblizing and defeating enemies. At the end of each level, the heroes give their Lums to the Magician, who grants them Electoons in exchange. At the end of the game, it is revealed that the Magician has been using these Lums to power the mechanical army he built in the Moody Clouds to take over the Glade of Dreams and rid it of the Bubble Dreamer.
Lums also form part of the culture of the Glade of Dreams, as the magic people use them as collectables during events. These events involve competitions between groups of four players, racing to get the most Lums and get the prize.
In Rayman Legends, Lums can be painted pink by Murphy, adding not only the regular amount of Lums for Rayman's score, but also the exact same amount of Lums for Murphy's score. This duplicates the final score of Lums, which are later used to unlock bonuses. Unlike the red colour generated by the Lum Kings, the pink colour of Murphy's paint is activated with the touchscreen, and appears to be permanent, giving Rayman enough time to take them all.
