The island of Dragontone also resided in a volcanic region and served as the home of House Targaryen before they invaded Westeros.
Targaryens were known for their connection to dragons.
Due to their history living among hot springs, many fans believe the dragons inhabited the grounds under Winterfell.
In fact, some believe, the springs, referred to by George RR Martin as “furnaces of the world” could be heated by the dragons.
