Tales of Borealis is a series of alternate future/universe skins in League of Legends. Set in a winter setting, champions try to gain Polaris' favor in order to receive the Aurora's gifts, or its punishments. Have you heard the stories of the Aurora? Cold and dark they can be, but if you're brave enough you'll find warmth and majesty grander than any dream you've had. So sit yourself by the fire and come listen to these Tales of Borealis.

Lillia's shyness kept her from gazing directly at the glimmering Aurora in the night sky, yet she remained steadfast in her role as Polaris' messenger. Until the ice melted and spring dawned anew, she would guard the Aurora's seed in her magical bloom and guide the new Winterblessed in fulfilling their duties.
