Convenient Reference Guide to Reme. These books come in three varieties, one for 5th Edition, one for Swords & Wizardry, and for Pathfinder 1e. They contain reference stats for use with the Region book for easy use at the gaming table and to convert the system-neutral book into your rules-system of choice, as well as detailed encounter tables for the region. Keep your reference stats and general description open at the same time in separate books. The stats contained in the Convenient Reference Guide are not included in the main book itself.
