Quote from : The Iron Queen Book

I saw Oberon charge into the fray on a huge black warhorse, glamour swirling around him, and sweep a hand toward the thickest of the fighting. Vines and roots erupted from the ground, coiling around the Iron fey, strangling them or pulling them beneath the earth. Atop a rise, Mab raised her arms, and a savage whirlwind swept across the field, freezing fey solid or impaling them with ice shards. The armies of Summer and Winter howled with renewed vigor and threw themselves at the enemy.
