He is tall and handsome, with red hair and long lashed green eyes.
Captured and freed Edit
Perrin releases Gaul later on in regards to a viewing Min Farshaw has "about an Aielman in a cage, and a turning point". After talking to Perrin and linking the Aiel "He Who Comes With the Dawn" to Rand al'Thor he kills some Whitecloaks with Perrin and then heads to Tear muttering words of the Aiel leaving the Three-Fold Land when the Stone falls. He is present later when the Stone of Tear is captured.
Accompanying Perrin Edit
He is asked by Rand to accompany Perrin to the Two Rivers where the Children of the Light have camped themselves. While in the Two Rivers he goes with Loial to shut down the Waygate, closing it off permanently.
 There seems to be an attraction between him and the Far Dareis Mai Chiad, even though his and Chiad's clans have a blood feud with each other. During the Battle of Emond's Field Chiad stays with him to fight Trollocs instead of going with Bain and Faile to Watch Hill. Gaul wants to marry Chiad but she doesn't wish to give up the spear.
He accompanies Perrin when Perrin leaves the Two Rivers to meet Rand in Caemlyn. He then goes with Perrin and is in the Battle of Dumai's Wells. He Travels to Ghealdan with Perrin and his army to track down Masema Dagar. He brings Elyas Machera into camp when Elyas manages to sneak up on him, a fact which impresses him.
Tracking Faile Edit
He goes off to try and track Faile, Chiad, and Bain when they are captured by the Shaido. He later captures Galina Casban and brings her back to Perrin to be questioned. He goes through the aqueduct to enter the town of Malden before Perrin begins his attack. Once Faile is found, he rushes off to find Chiad. After the battle, it is revealed that Chiad and much to his chagrin, Bain, are now gai'shain to him, as he defeated twelve Shaido warriors of whom were the ones who had taken both of them in the first place.
Confrontation with the Whitecloaks Edit
While traveling from Malden, Perrin uses him to scout ahead. He finds Fennel waiting for Perrin. He scouts the Children of the Light camp and observes they have captured Basel Gill's group. Perrin asks him to send for the Wise Ones just before his force is about to engage the Whitecloaks. He is part of Perrin's group that meet with Galadedrid Damodred to discuss parley with the Whitecloaks. Galad recognized Morgase Trakand serving him tea in the parley. Gaul is injured by his own arrow when a bubble of evil erupts making weapons attack their owners.
Perrin charges Gaul and Fager Neald to scout the area around camp to find where a gateway will actually work. It takes them several hours in any direction to find a place where one will finally work. He attends Perrin's trial in which Morgase rules that Perrin is guilty of killing two Children of the Light, though she leaves the sentence to Galad. He is present when Perrin creates Mah'alleinir and then declares to his followers his acceptance at becoming their Lord and leader. He reports back to Perrin that the Whitecloaks are aware of their presence, when Perrin's army Travels to the heights above the Whitecloak camp. He is part of Perrin's procession when they meet with Elayne in Caemlyn. He guards Perrin when he meets with Matrim Cauthon and Thomdril Merrilin in The Happy Throng. He Travels through with Perrin and the rest of his huge force to the Field of Merrilor to prepare for the Last Battle.
Into the Wolf Dream Edit
Perrin feels the need to do something about the Black Tower and Slayer. At first he asks his Aiel Wise Ones about entering the Wolf Dream in the flesh, but is refused and strictly warned about its danger. Gaul overhears him and asks if he can accompany him. Perrin feels Rands pull, so he travels to Rand in the Blasted Lands. Rand grants him a special gate so he can enter Tel'aran'rhiod in the flesh and again warns about the dangers. His friend Gaul still accompanies him, though Perrin makes him swear he will not fight Slayer, unless he is attacked and then only as a means of escape.
Perrin travels to the Black Tower to locate and take over the Dreamspike placed there, so he can draw Slayer out. Instead he meets Moonhunter (Lanfear); though he knows who she is, and tells her, she helps him several times, even explaining how to operate the Dreamspike.
Later Perrin leaves him to guard the entrance to the bore at the wolf dream. He does so along with wolves, considering them as spearbrothers. He is wounded by Slayer and saved by returning Perrin.
