“Everything has a place in Eberron.” Despite the many unique features of Keith Baker’s D&D setting, this has actually been one of its most common taglines. There are enough mysterious corners of the world, enough factions and forces and peoples, that pretty much anything can find its way into the setting. I’ve embraced that idea myself, to a point: standard evil deities instead become demonic Overlords, strange species pop up in the Eldeen Reaches and Xen’drik and Argonnessen. that sort of thing. But how do you go about literally giving everything a place in Eberron? Well, you might start by reading the Naturalist’s Guide to Eberron: Volume 1: Aarakocra to Azer by Matthew Booth on the DM’s Guild.
