Posted this already in another thread but since this could be HUGE im doing new one

I think this IS Kartana's Ultra Space

Why? Look at that little Orange dot in the middle. Its slightly glowing when you watch the trailer closely. Kartana is a very small mon. Its a grass mon and the area is grassy and the leaves also look like Kartana

Why are people there? Possibly brainwashed fallers? Remember what happened to Lusamine and Guzma? For some short time they lived in that world (probably few days). These people could be Kartana's guardians

The route layout looks very similar to Nihilego Ultra Space, like a corridor with a wider area at the end

Thoughts?
