Arghun was a warrior past his prime and with a pegleg, but still an exceptional archer and bowmaker. Nicknamed Tree Foot. he was one of Thorgal's few friends, and a native to the north-east coast of England today, where he ran an armory with his nephew Tjall.
Arghun lived with Thorgal and his family for a period of time, but later chose to remain and live in the Land of Qa. This was both because he had become enamored to Be-Ki and Man-gen, two Xinjin women who he would later marry, and because the climate was better for his rheumatism.. In doing so, he left the armory to Thorgal.
Arghun specialized in making bows and arrows, offering different types of bows and all types of arrows for a variety of uses. He manufactured the famous "double curve bow"; a bow based on the ones they use in the Orient and the Far East. It is less cumbersome than a classic bow, but requires a larger draw force. Presumably it's the same as a reflex bow. Thorgal saw a test model of the double curve bow in Arghun's armory, and later Arghun constructed a custom one for Thorgal, which fitted his size. The bow, described by Arghun as his "masterpiece", had a range which exceeded an ordinary bow's range by half.. Thorgal later had another armorer construct a second double curve bow for him, based on the design by Arghun, which he used to great effect.
