Create a character for a game who is an ephemeral, glowing creature resembling an orb or sphere. Its body should emit a soft, warm light that illuminates the surrounding darkness. The color of the light should change depending on the intensity chosen by the player, varying from white to golden or blue. The character does not have specific facial or body features, but its presence is always felt due to the light it emits. In motion, the character leaves behind a trail of light that slowly fades
