So I was watching the World of Light analysis by GameXplain on Youtube, and as they were analyzing the parts of the map that were shown in the direct, I noticed something:
This appears to look like some sort of Dark Castle, and I immediatly had to think of the Underworld Castle. Of course, it could also be a Castlevania castle or a castle of a different franchise. What made think even more of the Underworld Castle is this:
That's quite a contrast; light and dark. Does that sound familiar? Light and dark? Palutena and Medusa? Hmmm..
The blue symbol in the middle of the castle has been speculated to possibly be that of a boss fight.. you have to fight a boss in order to break a crystal that protects Galeem. This is not confirmed, but it makes. If this is indeed the Underworld Castle and there is a bossfight, then Medusa or Hades could be a boss.
I do have to say that the color scheme of the castle doesn't really match that of the Underworld Castle (though it definitely gives me Underworld and Medusa/Hades vibes), and for as I can tell, the structure doesn't necessarily match? But the image is quite vague.
Also, as I was looking at the second image more, I noticed the lava to the right of the light crease, which definitely matches the Underworld..
I'm really curious to find out more about this mode; it definitely looks like a lot of fun. And if Medusa does turn out to be a boss, then I'll take it!
