Sergeant the Younger, who was actually called, simply, Sergeant, was a Dragonlord who served in the reformed Phoenix Guard during the early years of the Reign of Zerika the Fourth. His father, also called Sergeant, had served under G'aereth and Khaavren in a similar capacity during the Reign of Tortaalik.
During the Battle of Adrilankha, a band of Dragonlords serving Skinter, under the command of Tsanaali, stormed the new Imperial Palace in an attempt to take the Orb. Sergeant the Younger was killed while attempting to stop them.
After Khaavren and Pel successfully thwarted the attack, Khaavren attended to Sergeant's body by closing the poor guardsman's eyes.
