The Children's Tower is tall, slender and green with moss. It has only half of the crenelations of its crown, it looks as if some great beast has taken a bite out of the crenellations along the tower top, and spit the rubble across the bog. Its shattered top is open to the wind and the rain.
A Game of Thrones
A Dance with Dragons
During the siege of Moat Cailin, Ramsay Bolton sends Theon Greyjoy to offer the ironborn garrison of Moat Cailin food and safe passage if they surrender to House Bolton unarmed. As he passes the tower on the way to the Gatehouse Tower, he sees pale faces peering through the broken masonry crowning the structure. He is later informed by a guard that all of the ironborn within the Children's Tower are dead after Dagon Codd went over a few days ago and discovered two survivors eating the corpses of the deceased and killed them both. The pale faces signal the crannogmen retaking the tower.
