I’m fascinated by this first look at the Dark Kingdom. While the classic anime made the Dark Kingdom some kind of nightmarish dimension and PGSM set it in a literal cave, the manga had depicted it as an old building with pillars. Crystal took that one step further, though.
The torches are lit with an eerie green flame, suggesting how much the environment is influenced by magic. Outside, you can clearly see snow falling. That means they are quite literally at D Point of the North Pole, not just on the other side of a dimensional rift that happens to be located there. In one brief shot, you can see thorn-covered vines wrapped around some of the pillars.
Now, I’ve always headcanoned that the manga Dark Kingdom’s building was some relic of the past, either transported or reconstructed from one that existed in the Golden Kingdom. And while we may not get a rose-throwing Tuxedo Mask in this version, I think it’s fair to say that Mamoru will always be associated with roses. So what does it imply that there are rose thorns here in this place? Are they already implying the Dark Kingdom’s connection to him?
OH THOUGHTS ABOUT ROSE THORNS.
I wonder if D point has any connection to Elysion. Like, what if D Point is really just Mamoru’s old kingdom. As we know Mamoru’s family in particular was connected to Elysion, maybe the gateway to Elysion was also at Mamoru’s kingdom.
We know Elysion was able to protect itself for a long time since Earth does not show signs of dying until Elysion is overrun by Nehellenia. So what if the only reason Nehellenia was really able to break through to Elysion is because it had been absorbing dark energy and damage from the Dark Kingdom a few years prior?
At the same time, there are manga images showing Mamoru’s kingdom wasn’t in a swirling blizzard, so maybe it wasn’t at D point. XD; Though I suppose it could be plausible that it could be a secondary castle or something meant solely to protect the portal to Elysion.
What if D Point wasn’t always cold? The magnetic north pole is always changing, what if thousands of years ago that particular area was not the North Pole?
OR maybe like you say, that was just one of the entrances to Elysian. Maybe that was sort of a fort or base.
I would point out that the shrine of Elysian is also full of pillars.
