Thanks to everyone who has contacted me or provided guidance concerning this matter. The short answer is that Nocturnal Media is still the owner of WEG/D6/OpenD6. I'm not seeking any more information on the matter but publicly urge the owner to consider releasing OpenD6 under a Creative Commons license (or something similar) in the event that the OGL drama creates ambiguities or ends the current 1.0a license.
Please do not reach out to anyone or send any messages on my behalf. I respect the privacy of all involved and don't want to annoy anyone. I'm happy to receive any news regarding the status of OpenD6 from the owner or anyone authorized to speak for them should they choose to communicate publicly or privately.
It's obvious that until things become official and clear regarding WotC's position, there's no way anyone can definitively say what should be done.
A few years ago Nocturnal Media purchased West End Games and with it, the D6 system and OpenD6 property.
As I understand it, the founder of Nocturnal Media passed away. Nocturnal's website appears to be gone, and a quick search didn't turn up any recent activity or contact information.
Gallant Knight Games have some relationship to OpenD6 in some sort of official capacity, but I'm unsure of the exact relationship. I reached out to them tonight to see if they have any information on current ownership.
The reason I ask is that the credible-appearing leaks concerning Wizards of the Coast revoking the OGL 1.0a would have implications for the OpenD6 world, and by extension, Mini Six. I'd love to talk about it with the owner of OpenD6.
