I reread Startide Rising and The Uplift War recently, and it occurred to me that that interspecies dynamic would be an interesting way of handling the profusion of intelligent races in an “everything in the books”-style D&D campaign. Sure, maybe bugbears and ogres are basically the same thing, but that’s just because the illithids thought the aboleth had too good a thing going with ogres to let the idea go unswiped. If you have a problem with that, I’m sure the beholders will be happy to field your complaints about their client race. Or their patrons, if you can find the right Outer Plane.
