Illustration of a Ngombi, a traditional arched harp from Central Africa used in Bwiti rituals. The Ngombi is depicted with a monoxylous wooden resonator and a curved neck, featuring eight gut strings fastened by wooden pegs. The instrument is enveloped by celestial flames, bright and ethereal, surrounding it without consuming it. The celestial flames should be illustrated with vivid and translucent colors, evoking a mystical and sacred aura. The background of the image should be dark to highlight the brightness of the flames and the beauty of the Ngombi. The entire scene should convey a spiritual and magical atmosphere, paying homage to the ritual significance of the Ngombi in Bwiti ceremonies.
