Before the Last War, Artur is was a stereotypical forgetful professor, often forgetting to eat, sleep, or clean himself on a regular basis.
Artur was recruited to the Cyrian army for his technical expertise, and assigned to a unit that worked with Cannith's newest creations: The Warforged.
Artur was made to undergo basic soldier training along with the Warforged, and this changed him as a person.
When the Warforged were deployed to the battlefield, Artur asked to go with him. By this point, Artur had become a focused, orderly, and driven young man.
Artur was prompted to Captain and put in charge of a company of Warforged that was sent to serve under the banner of Breland. During the course of the war, Artur's unit was honored by the Brelish military for being willing to take on any mission and succeed.
Then, however, The Mourning occured.
Artur's unit was returning to Korth when they heard the news; unlike most of his countrymen, Artur did not really take the loss of his country as hard as they did. He had long since ceased considering himself a Cyrian, and only marginally considered himself a member of House Cannith.
Unsure of what to do with himself after peace was declared, Artur moved to Sharn and took up residence and began hiring himself out to as a troubleshooter and adventurer.
