Delver's Guide to Illumination

This small accessory for F20 table top role-playing games updates and adds light sources from the originals. The original stats have their roots in the 70s and unknown data. The realistic light sources on this booklet are based on real world data (including experimental archeology, optics and physiology of human vision).  The biological ones are inspired by real world bioluminescent organisms (although some are more powerful). The alchemical light sources are based on different luminescent real world phenomena.
