All it took was a simple “huh, that’s interesting, I didn’t know they had goblin words.” Hidden within the monster-strewn pages of the 5th Edition Monster Manual are myriad references to the editions that have come before. You’re never a tourist in your own city–but sometimes, all it takes is someone new to come along and point out something that’s been there all along that you’ve just never noticed. D&D’s Monster Manual isn’t just full of monsters – it’s packed with loads of inside jokes and Easter Eggs.
