Halt is a highly qualified Ranger, and the mentor of Will Treaty and Gilan. Although often described as grim and unfriendly, he actually has a very soft heart that he only lets people close to him, especially Will, really see. This is shown, for instance, in The Burning Bridge and The Icebound Land when he publicly insults King Duncan in order to be banished, so he can travel to Skandia and rescue Will. Originally the Crown Prince of Clonmel, Hibernia, he escaped to Araluen at a young age after his twin brother, Ferris, tried to kill him multiple times in order to gain the throne. He is famous throughout all of Araluen for his mysterious ways and seemingly unstoppable nature.
