Limn is a product of Natural Personification, as modelled in the Universal Strata Model it is a product of other parts of Nature creeping into Reality. Limn is a strange Real-esque entity which does not obey the laws of the Unreal. Limn is not composed of typical material structure, but instead appears to consist of a grid-like fractal pattern which repeats infinitely.
Limn subverts measurement, it is weightless but takes on a defined form and volume. Limn is easily compressed into larger segments by binding its fractal structures together, and easily torn apart by shearing these structures apart.
Production & Application
Limn naturally materializes throughout the whole of Reality, appearing at varying microscopic sizes. Limn is accumulated in ecosystems through the food chain, absorbed passively by organisms like plants and vermin. These basal organisms do not typically use the Limn for anything in particular, it is not until further up in the food chain that organisms use special limnary press organs to turn digested Limn into useful artificial stars.
Limn is used by humans, dwarves, and elves to craft their own artificial stars, though in all three of these organisms there is no such limnary press present. Artificial stars themselves are used for a variety of purposes, but for more information on their use see the page on stars.
Limn is harvested by different cultures across the Plane in varying ways.
