Welcome to the frozen North - a windswept and war-torn region home to some of the most resilient people in all of Runeterra. Here, three great tribes vie for control of their icy homeland. The Avarosan, led by Ashe, strive to unite the Freljord under a banner of peace. The Winter's Claw, boldest and most warlike of the three, follow Sejuani on her campaign of conquest. And the Frostguard, secluded and mysterious, bide their time haunting ancient ruins alongside Lissandra, the Ice Witch. As they prepare for war, something ancient and sinister stirs deep beneath the earth, threatening to corrupt the land itself.
