As we can see in this strip, both the western continent and the continent comprising the "north" and the "south" are on the same half of the globe that is ootsworld.

But we also see pink lightning extending around to the other half of the planet that we can't see. I don't believe we've ever seen any mention or reference of what might even be over there, it could be a Panthalassa scenario. But then, that begs the question, why is the lightning going there? Do black dragons (or half/quarter/eighth black dragons) enjoy spending time in an ocean that spans half a planet? Or are there continents as yet unseen in the comic?

I don't have any answers for this, it was just something I noticed when rereading the comic and wondered if anyone else had noticed it too.
