This is my write-up of my Changling Artificer from Cyre. He isn't actually attached to the military, but he very likely sought some military types out after the Mourning. I hope you like it.
Tok: LN Changeling Artificer 2
Tok wanted nothing else in life than to rise above the common misconceptions that his homeland, Cyre, showed his race. At a very young age Tok showed a keen mind and almost intuitive knowledge of the inner workings of minor magic items that his father, Kron, aquired at “work.” Noting her son’s abilities, Tok’s mother, Yul, used her natural changeling charm to establish a few contacts at the House Cannith headquarters, earning her son an apprenticeship with the prestigous House Cannith Artificers.
Tok enjoyed his apprentice work and making an honest living. An elderly blind elven seer-woman named Keidi frequented the tavern where the apprentices often spent their time. Tok, shunned by the other apprentices due to both his superior abilities and the dubious reputation of his race, felt oddly drawn to her and she took to him very quickly.
One night a frenzied knocking came at Tok’s cell door, and standing there in her ratty robes, looking disheveled, stood Keidi. She cast a spell over Tok placing him in a bewildered haze, giving him instructions that seemed very important at the time.
Tok began to come out of his haze just before the lightning rail he found himself on crossed the Cyran border. He was wearing Keidi’s clothes, wearing Keidi's face, carrying her traveling papers, and carrying a small, magical object. He remembered that he was forbidden to speak of it or show it to anyone. Not two seconds after he realized this, an explosion rocked the train car, throwing it from the conductor stones.
Tok, sometimes as himself, sometimes as Keidi, has sought out other Cyran refugees, hoping to piece together some information on what caused the Mourning, and hoping to find some clue that will tell him what the mysterious object Keidi gave him does. And every day he hopes that the two questions that drive his existence have NOTHING in common.
