Artaith readies her shield and axe. "Get back and stay back!" She takes just enough steps forward to make sure she's the closest person to the Ogre. "Yngret Yellowhair, lady of accord, protect us!" In a sudden flash, Artaith's axe glows red. Wreathed in flame, she takes a bold stance between the Ogre and her allies.

She begins muttering, chanting under her breath. "Warm our hearth and embolden our arms. Be the shield that protects us from harm."
