Khadolin's career as a Knight, his dream since youth, had taken a path neither he, nor anyone else, had even known to be possible.
When his opponent in a friendly tilt of all things had accidently lanced his horse, he'd wept. Only halfway through is time as a squire, he'd begun forging a bond with his horse that he knew he could never be replaced, so when he wept, it was not only for his own pain, which was great, but for the loss of his companion.
His own pain though, wouldn't be forgotten. Crushed under the weight of his dead steed, Khadolin suffered serious damage from which even the more-than-adequate healers couldn't fully help him fully recover. Truly, they did a marvelous job-- Khadolin initially wasn't sure he'd ever even walk again-- but he couldn't help but be disappointed that he couldn't stand to wear even a mail shirt without every inch of his damaged back screaming out in pain. Khadolin, however, wasn't about to give up on his dream so easily. Taking a leave from his service after he gained a reasonable level of mobility back, he traveled East, where he'd heard that warriors learned to fight without armor.
Khadolin found an enclave of such warriors, and after much struggle, came to understand the monks he'd found. The kind men and women of the monastery took pity on his injury, and after they grew to appreciate Khadolin's noble aspirations, agreed to train him. Finishing what would be the balance of his 'unique' squireship, Khadolin learned bodily control and unarmed combat, conquering his disability, though still unable to wear armor, and unwilling to form a bond with another mount. Passing the basic tests given by his teachers, though still impossibly far from being a Master, Khadolin took his leave to return home, his heart still set on serving his King and Kingdom as a Knight, somehow.
Returning however, was harder than he'd thought. Though he was far from forgotten, and many were rightly impressed with his recovery and turnabout, he was unable to regain his place in the knighthood with its rigid policy and structure. His style and personal limitations fit very poorly into the Knight's Code. Unwilling to back down, Khadolin took the only job he could get, enforcing the law as a Constable. He served for a year with honor, bringing a noble and honorable bend to an often-overlooked profession. Khadolin earned the respect of his peers, enforcing the law efficiently and with relatively little violence.
As a reward, Khadolin was knighted with Arthur's newest lot of knights, and while he remains incredibly excited, he'd be lying if he said he knew what his King's intention in bring him into the fold was, exactly.
