The world of Greyhawk, planet Oerth, destroyed Blackmoor. You can see its ruins in the far north on the map. There ended up acrimony between them, after the legal battles.
Mystara preserves Blackmoor.
It would be cool if a new Greyhawk resurrects Blackmoor. (Forgotten Realms has done weirder things!)
Actually, the ruins of Blackmoor according to the Greyhawk Oerth seem too far inland. It looks more like the ruins of Ringlo Hall in the Elven Forest. Whereas the town and castle of Blackmoor themselves are on the coast (one hex space west). So perhaps, the ruins are of a prominent nearby city, while the "old city", the ancient town of Blackmoor, is still populated and existing on the coast.
I completely forgot Al-Qadim, to my shame.#1 was Al-Qadim (I had to write it in because, despite being shoehorned into the Forgotten Realms for its entire existence, AQ is so different in its approach and world building that it's never fit well there).
Are you referencing that time that the Dragons built a giant magic laser cannon and shot the moon in the Forgotten Realms? Because that actually was quite important in my Spelljammer campaign.Oh hell, Greyhawk could resurrect Blackmoore by shooting Blackmoore into the Forgotten Realms with a giant magic space cannon power by positive energy from the positive energy plane, and the Forgotten Realms will still have done weirder things, and that is just this edition alone.
Wait…that isn’t what “people” means. Like in pretty much all speculative fiction discussion, and non-fiction discussion of hypothetical other intelligent species, “people” refers to all sapient creatures.If you look closely, you'll see those are elves, so... not 'people' at all in terms of humans...
Blackmoor is just a normal location in Greyhawk.Blackmoor could be "resurrected" as a demiplane created by great powers creating refugess for their followers. Practically a remake. It wouldn't be worse than the Sundering event in FR, but if my memory doesn't fail WotC is not the current owner of the copyright. A partnership deal?
I imagine Nentir Vale like a transitional setting, this means with "Stargates" to other D&D worlds, allowing visiting and being visited, and with this we could explain the reason because a kender could appear in Greyhawk or a gith in Krynn.
