Warband

From Guild Wars 2 Wiki

The Warband is one of the most important aspects of Charr culture. During their education and training in their legion's Fahrar, every young Charr is forced to become a member of a warband, usually adopting a surname indicating their membership. For example, they could choose the name Fierceclaw in a warband where members identify themselves with the word Fierce. They will continue to train with their warband, as the warband becomes their new immediate family. It is important for the new Charr to be accepted as the warband must function like a well oiled machine, whether on the battlefield or simply surviving the dangers of the wild.

Whereas a Charr's individual loyalty lay with their warband, the warband's loyalty lays with their legion. The size of a warband can vary; the exact degree of which is unknown, though some like Pyre Fierceshot's warband seemed to be made up of only about a dozen or so Charr.
