Re: Tal'Dorei campaign setting: Green Ronin must have some kind of agreement with WOTC to use certain things, because it features Goliaths and Genasi (and the Goliaths have two NPC stat blocks in the back of the book). It also mentions D&D, the Feywild and the Shadowfell, the Frostfell (aka the Plane of Ice), the DMG, Draconians (?!?), and a few other such things. The Pantheon of Exandria looks like a combination of the 4e D&D pantheon and a couple of additional FR gods with the names shaved off (i.e. The Matron of Ravens = The Raven Queen, The Ruiner = Gruumsh, etc.) Some of the background details make the identification of some of these hard to deny, for instance The Ruiner losing an eye to the Archeart (Corellon). Since this is Green Ronin and not some fly-by-night company, I assume they must have permission... BTW, are the names of any of the gods used in the Critical Role podcasts? I haven't seen them, so I don't know if the group used the original D&D god-names in their games.
