Magicae Prismatica is a series of alternate future/universe skins in League of Legends. Set in a world where magic has returned and champions use the Prismae Crystals to harness it. Magicae Prismatica officially encompasses two skin lines: Crystallis Motus and Crystalis Indomitus. Long ago, in a time beyond all living memory, the existence of magic was swept away from the universe. Life moved on, but some worlds could not, and as years turned to decades and centuries, nature began to rebalance itself. Finally the time has come, and now magic is ready to make its return, though not in the form that anyone expects.

Ashe's retreat from her northern homeland was not due to any invasion, but the Prismae Crystals. In such a harsh environment, their power was difficult to resist, leading many to lose their minds and bodies to its magic. Forced to find shelter in the south, Ashe now gathers an army to take back her home from the monsters that overrun it.
