The GM Handbook is well-divised, thoughtfully arranged, and indispensible for your World of Farland campaign. Although supercharged for DnD 5e, the setting, beasts, tips and mechanics are easily applied to any system or campaign setting. Full of original baddies and a full breakdown on the Lords of Sin, this handbook captures all the info a GM needs from the wealth of online information. As an added bonus, the full-color map is gorgeous and inspires a mulitude of adventures just looking at it.
