Giygas- Ghost Doors

The Warriors seemed to have become lost little children. It felt like they were going around in circles, with each place looking exactly the same as any other. Where was the room with the piano, and which way was the exit? It all felt so disjointed and incomprehensible. In the typical behavior pattern of those who are lost, they were going back and forth, up and then back down, retracing their steps over ground they had already covered time and time again. They were trying to hurry, but they were also being repetitive, and they had wasted a terrible amount of time.
	“...It's no good! This is a dead end, too!”
	Ana heard Lloyd's voice ahead of them, and he sounded frustrated.
...

And then, from the wall across from them, from the floor just to the side of them, from the ceiling, from the fancy columns, and even from a portrait hanging on the wall...so many ghosts, of the exact same shape and size, popped out and began to float toward them!
	 “What the?” said Lloyd. “It multiplied! Aha, these guys are sort of like alarm clocks, aren't they? It appears they have a habit of calling out for their friends by sending out a loud sound right as they're about to kick the bucket. Hmm...this is tough. Oh I know! I'll call them, 'Alarm Ghosts'!”
...

“............!”
	Suddenly there was a light...!
	Beyond bright, beyond the purest white, and causing a momentary blindness, a small speck of intense, powerful light appeared soundlessly, and then all at once, like an explosion, it began to spread...!
	Before too long, the wounded Warriors regained their vision, and they could see that aside from themselves, there was absolutely no sign of life or movement around them. The ghosts had all been crushed...or disintegrated...or mowed down by that powerful light, and they had vanished.
	“Wh...what just happened...?” asked Lloyd, as he sluggishly got to his feet. “It was like a supernova explosion. Or could it have been...a theoretical white hole...?”
	“Whoa-ho. That was pretty cruel of you, Ana.”
...

She gave a soft sigh.
	 “Heeey! Over here, over here...come look, come look!”
	Lloyd peeked out at them from a room at the top of the stairs.
	 “This is amazing!” he said. “There's a door here we didn't notice before. And that hallway we passed through so many times just...isn't here at all anymore! I bet that light just now destroyed a bunch of fake doors that were turning this place into an endless maze!”
	“Alriiight!” Ken shouted.
	...And then he ran off at once.
	Without even a “Let's go!” or anything like that.
	Ana breathed yet another sigh, then hurried along after the other two.
	Once the tricky phantom hallway that the nasty spooks created had disappeared, there was no need to search the rest of the mansion. At last, the three of them found themselves in a room with a large piano.
...

They supposed that the powerful white light had been the cause of this fortunate turn of events. The townspeople of Spookane had completely returned to normal, too.
