Snowdown is a series of alternate future/universe skins in League of Legends. Set around the mythos and festivals of Runeterra's Time of Snowdown and real-world winter holiday festivals (most notable one being Christmas), all of the champion skins were inspired by these regional or festive cultures.
Snowdown officially encompases three skin-lines: Snow Day, Snowdown Showdown, and Winter Wonder.
Is there a better time of year than Snowdown, when the air is crisp, the snow fluffy, and the chocolate hot? Toss a snowball or sing a carol; as long as you have good cheers, all will be well, and you'll have nothing to fear.
