Looks like you're in a pre-historic, 200 BC, roman based, greek based, futuristic, fancy, liminal, unknown, mysterious level that is not been discovered

Take the escalators, they look Neon, Neon Levels are safe.

Don't make me repeat again. This is basically an undiscovered level so any impossibilities are possible.

There might be a dangerous entity or you are already lost there.

Ok, try and look for entities, if you see one, report it.

Nah, Its the sidewaysrooms
