Barlow was a former Greencloak, having left his post to become an explorer. His best friend was Monte. His spirit animal was a bear named Jools. Though described as intimidating, Barlow had a good sense of humor and often laughed along to Monte's jokes.
Barlow left the Greencloaks along with Monte to become an explorer. They set up many trading posts and explored Amaya.
When Barlow and Monte were found at the trading post by Essix, they decided to help the Greencloaks find the Granite Ram of Arax. Unfortunatley, Barlow and Jools met their death atop a mountain slope; Arax violently flung Jools to his death, but right before Jools died, he gave Barlow incredible strength when he flung Arax off the mountain. Barlow was stabbed by Zerif after saving Abeke, which prompted the young girl to fight for the Greencloaks instead of the Conquerours. Barlow's final wishes were for everyone to be told about his incredible feat of power and to be buried in a green cloak. He was buried in one of Tarik's cloaks outside of Sunset Tower.
In the Books
Barlow is first seen when Monte brings the main group to him in a back room. He was first skeptical, as he lied about his knowing the location of Arax. When Rollan caught onto Barlow's lies, Barlow questioned the Abeke, Conor, Meilin, and Rollan's spirit animals. Jhi was taken out of dormant form (Essix was already out), but Barlow thought it was some kind of joke, at least until he saw Briggan. He and Monte then led the group to and through the mountain and joined in the fight against Arax. While charging, Arax at one point got angry and flung Jools off a cliff. Right before Jools died, he gave Barlow so much strength he could lift Arax up and throw him off the mountain after he tried to hurt Abeke. When Barlow asked her if she was alright, Zerif stabbed him in the back and he died after requesting tales of him throwing Arax, and being buried in a green cloak, causing Monte to renew his Greencloak vows.
