Andere is a Malkieri who was sworn to a Kandori lord (NS, Ch. 15). When Lan rides across the Borderlands, Andere joins Lan in Saldaea with Nazar and Rakim. Lan had not seen him in many years. He is a lean, dangerous looking man who wears the hadori (ToM, Ch. 7). Initially Lan tells him not to join, but relents when Andere refuses to go away, saying he would only obey a king (ToM, Ch. 7). When Lan readies himself for the charge at Tarwin's Gap, Andere rides on his left (ToM, Epilogue). He is injured in the fighting and Healed by Deepe (AMoL, Ch. 16). When Lan grows suspicious of Agelmar, Andere is one of the men he discusses it with (AMoL, Ch. 28). He survives until at least the Battle of Merrilor (AMoL, Ch. 37).
"You stand ready for what boy? You cut your hair short and leave it unbound. By what right do you claim to be a Malkieri?" (Bukama; New Spring, Chapter 15).
"I'm no longer the boy the Hero of Salmarna berated so many years ago." (Towers of Midnight, Chapter 7)
