Father Adler is one of the oldest members of the Resistance and one of the last Gadoba Trees in existence. His brothers were burned down by the Army of Gulfen under Luger's command. He is very wise and is able to foresee future events.
Balan took Navin to see Adler in an underground cavern. Navin asked Adler what would happen to his sister. Adler explained that most of the images he could see were foggy, but that one image in particular was clear. Adler told Navin that he could see Emily falling off a cliff to her doom. Navin, fearing for her safety, immediately left with Morrie. Balan called out to Navin that he had yet to see into his future, but Adler excused this.
