Kaen is a tall, lean tiefling with ash-gray skin, swept-back black hair, and long crimson horns marked by faint silver scars. His eyes glow a muted amber, though his expression often carries the distant emptiness of someone who has awakened from a very long dream. He wears battered scale mail beneath a dark military coat, with brass artificer tools secured across his belt. Nyx, his strange revolver, is always within reach. Its black metal frame is etched with symbols resembling both funerary script and clockwork diagrams.

Kaen is quiet, observant, and unfailingly deliberate. He carries himself like a commander who expects danger even in peaceful rooms, yet his instinct is to protect rather than dominate. He is unexpectedly gentle with wounded animals, broken tools, and frightened people. Around monuments, old battlefields, or wedding customs, fragments of warmth and grief sometimes surface before vanishing behind his practiced restraint.

Hundreds of years ago, when the Seven Kingdoms were only two, Kaen Flame was a legendary general feared by his enemies and respected by the soldiers who served beneath him. He had once been a nameless street orphan, surviving through theft and murder before an elderly mentor took him in. The old soldier did not pretend Kaen was innocent. He taught him discipline, purpose, and the difference between killing out of necessity and killing by choice. Under that guidance, Kaen entered military life, rose through the ranks, and eventually became something more than a destroyer. He learned to build weapons, repair armor, and turn ingenuity toward preserving life. His campaigns ended with the two kingdoms united into a prosperous empire, and he secretly married the one person who made peace feel more meaningful than victory. The marriage was meant to remain unknown, but enemy agents discovered it. During the private ceremony, assassins struck, killing Kaen's wife and leaving him hollow. He disappeared into years of grief. As the empire fragmented without its founding general, Kaen sought a way to undo death. His experiments created the first necromantic magic, not from malice, but as a desperate love letter written in blood, memory, and impossible machinery. It worked. His wife returned, but the spell tore open a temporal bubble that trapped Kaen outside the flow of history. When the bubble finally broke, he awoke in an age of seven rival kingdoms with no memories of his life, no understanding of the world, and only Nyx in his hand. The revolver is his sole surviving weapon and perhaps the last key to recovering the truth.
