So I just heard of the upcoming Dark One OGN like last week and was reminded of it today, but apparently it's been known/hyped for some time (even has its own subreddit dating back to last year?).

In that link, they say they have more upcoming OGNs. In my experience, Vault is pretty slacking on their website update. But they updated for Dark One. Their twitter is really active, but mostly retweets. ...a LOT of retweets. Anyway, does anyone know of these upcoming OGNs? Is it all part of the same Dark One universe or just separate stand-alone OGNs? Both?

Thanks for any info and input.
