User blog comment:PlaguedWings/Demon's Souls 2: a fun little thought/@comment-6003396-20140115103409/@comment-11064372-20140116053915

The thing about the demon's souls and dark souls games... is the fact that the rights to each game is owned by a different company... which makes it so that for now... they can not OFFICIALLY link the worlds as being in the same planet... or even universe. So, instead they leave easter eggs and random stuff from each others games to kinda make is seem like they might be. But it as of now... can not be confirmed. (Just read up on this)
