City of White (3)

What exactly is this situation?

Looking at the wilderness before him, Rhode stretched out his arm blankly to scratch his head. After he agreed to the little queen's request, she sent someone to escort him out of the city. Later, he didn't even know what happened. He simply witnessed a flash in his vision and was transported to this deserted wilderness the next second. Everywhere was empty. The candy city from before was nowhere to be seen. But that didn't surprise him much, since this was how it was in a mental world. And if one were to make sense of everything, perhaps it would be meaningless other than confusing one even more.

"Alright then, looks like I'll need to defeat that giant next, huh?"
