From publisher blurb: Crammed full of over two years’ worth of 20 Things articles, The Thingonomicon is an essential resource for the time-crunched GM striving to add depth and verisimilitude to their game. Comprising almost 200 pages of detail-heavy, system neutral tables The Thingonomicon can be used either both or during the game session. If your campaign features goblin lairs, kobold warrens, smugglers’ dens, cultists’ lairs and many more iconic adventure locations, the Thingonomicon is for you!
