A classic camping lantern as a single hero prop: a metal frame with a carry handle, a
glass enclosure around a warm glowing core, standing on simple ground.
The floor is a recognizable lantern that glows. The ceiling is what the light does:
warm light passing through the glass, a soft pool of illumination on the ground,
