Kebi is a lean, medium-sized tiefling with umber-red skin, swept-back black horns, a narrow face, and a long tail that curls around his ankle when he is thinking. His pale green eyes rarely settle on faces. Instead, they track doorways, windows, shadows, and the hands of everyone nearby. He dresses in a weather-stained dark robe over practical travel clothes, with a silver holy symbol from a forgotten temple hanging beside a softly glowing green crystal. The crystal is usually suspended in a cage of blackened wire at his throat. When Kebi becomes agitated, faint green light traces the veins in his hands, and the air around him smells briefly of rain on hot stone.

Kebi is observant, self-contained, and disarmingly direct. He can spend hours walking without speaking, then interrupt a tense negotiation with one sharply accurate question. He is curious about nearly everything but emotionally evasive about himself. Although he claims to prefer solitude, he quietly studies the habits of companions and remembers small details they assume he has missed.

Kebi Ravensworn remembers no childhood, no family, and no home. His first memory is waking in a ditch beside a forgotten road, soaked by cold rain and surrounded by trampled weeds. He wore travel-stained clothes that did not feel familiar, and clutched a strange green crystal that pulsed with a patient inner light. When he tried to throw it away, a voice spoke inside his skull. It did not give him a name or explain how he had come to the road. It only told him to keep walking. The crystal led him, through dreams and sudden flashes of impossible knowledge, to a remote temple where an elderly priest mistook his strange powers for a divine calling. Kebi learned prayers, funerary rites, sacred languages, and the discipline of serving people who were frightened or desperate. Yet the crystal continued to whisper beneath every hymn. Its voice is neither kind nor cruel. It calls itself a conduit, a window, and sometimes a patron, though it refuses to say what lies beyond it. Kebi eventually left the temple before its elders could decide whether he was blessed or possessed. Now he wanders alone, using sorcery that burns green and gold, searching for the forgotten road where his life began and the intelligence on the other side of the crystal.
