Cordwood "Cordy" Mather appeared for the first time in the book Shadow Games.
Cordy was from the Free City of Roses, where he had served in the military, and had traveled thousands of miles south with his friend Willow Swan. On the way, they rescued a man named Blade who had been thrown to the crocodiles. Blade joined them in their travels and they became a close-knit group.
Taglios had been pacifist for generations, so the Taglian royal family approached him, as well as Swan and Blade, to organize the protection of Taglios against the first invasion from the armies of the Shadowmasters. He used tricks that he had learned from the Black Company's campaign near Roses to trick the Shadowmasters army into small prepared towns which were burned around them. They destroyed the five thousand man force sent against them, and set out to welcome the Black Company and attempt to enlist them into service.
Cordy watched the Battle of Dejagore from afar and witnessed the Taglian forces lose. Taglios had become his home, so he began work to continue its defense and the war against the Shadowmasters.
He became a paramour of the Radisha Drah, the sister of Taglios's prince, the Prabrindah Drah. He served closely as her advisor at this time and is sent out to investigate the progress of the war as Croaker launches the battles of Charandaprash and Overlook. He is captured by Croaker's forces after the Prabrindah Drah betrays them and is forced to proceed on the scouting mission onto the Plain of Glittering Stone. He is trapped along with the rest of the Captured in the ice caverns by Soulcatcher.
For reasons unknown he awakens from stasis in the ice caverns and attempts to awaken several friends, killing them instantly. He then attempted to crawl down a small side passage but is killed by a mechanical booby trap.
