As Ares arrived Thor said to Brunhilde "Aye. Good hunting. If thou art overwhelmed hesitate not to call for aid. No Asgardian shall perish this day."
He met Ares at the outer wall and clasped forearms with his oath-brother and said "Thou art underdressed Brother. Asgard is embroiled in a sea of biting winds and numbing cold. We shall have to keep fighting, lest thou freeze until spring." The Thunder God himself was wearing warmer clothing and a wolf skin cloak.
Frost giants approached as Thor raised Mjolnir high and cried out thunderously "For Asgard!!!" And the rally cries of the warriors of Asgard thundered through the air around the Eternal Golden City with enough force its sound drowned out the howling winds as the battle began in earnest. With a run Thor Odinson struck the first giant he saw crushing its skull.
