A warrior bonded to an Aes Sedai through a weave of the One Power, also known as Gaidin. The bond grants enhanced physical abilities - quick healing, resistance to fatigue, the ability to sense Shadowspawn - and creates a mutual awareness of each other's physical and emotional state. Most Ajahs permit one Warder at a time; the Green Ajah allows multiple; the Red Ajah traditionally bonds none. When a Warder dies, the Aes Sedai feels it acutely; when an Aes Sedai dies, the Warder is often driven to suicidal fury.
