Lamphéjl

Lamphéjl is a fictional luminous gem described in speculative fiction and tabletop role-playing game lore as a portable light source. In most depictions, a lamphéjl is a small, delicately cut gem that emits a steady glow without flame, produced by a self-contained luminescent core within a transparent matrix. It can be recharged by exposure to ambient energy or through simple handling, offering several hours of illumination suitable for travel or ceremonial use.

Etymology and form: The name lamphéjl blends lamph- from lamp and éjl, a phonemic element from the fictional language of the Elarin peoples meaning jewel. Lamphéjl vary in shape from ovoid to teardrop and are typically about the size of a grape, though larger ceremonial pieces exist. The luminescent core is commonly described as a mineral or glass containing microcrystals that fluoresce or phosphoresce, giving the gem its characteristic light.

In-universe history and use: Historically, lamphéjl appear along coastal trade routes and in urban centers of the Vassari dominions, valued for safe nighttime navigation and as indicators of status. They feature in legends and ritual contexts, sometimes placed on altars or worn as pendants during night markets. Some in-universe texts outline technological methods for manufacturing lamphéjl, while others treat them as magical or alchemical artifacts whose glow can be influenced by environmental or symbolic factors.

Modern reception: In contemporary tabletop settings, lamphéjl function as rechargeable light sources and narrative devices, with variations that glow in different colors or respond to spoken commands. Collectors and merchants track lamphéjl as curio items, and new designs continue to appear in game supplements and fan fiction.
