The Mansion In The Forest ((Not a jump-in))

[Lusterless Nova]

I'd say we get out of here.

[Lary]

"Bah, what are you worried about? It's harmless."

[PrincessButton]

"Harmless??!" 

[Lary]

"Oh come on! This is like, the fifth time I encountered this mansion! It's always the same thing. Ponies go in, and they don't come out for weeks. Mansion disappears, nopony remembers a thing!"

[PrincessButton]

"They've been mutated into monsters! How's that not harmless??"

[Lary]

"That's just a false copy. The ponies trapped inside are in some hidden room. They'll be fine, save for a slight case of memory wipe.

Trust me. I've seen this whole thing before... Every pony that gets captured in there, another room is added."

[PrincessButton]

"What? And you waited until now to tell us all this? Where are they? How do we save them??"

[Lary]

"The ponies trapped inside? Eh. They'll wake up there without a single thought about the place once it's gone. Perfectly unharmed. As for the original blue thing, I don't know."

[PrincessButton]

"Greeat...." 

[Lary]

Lary gets up and hugs Moonbeam tightly. "It was still dangerous in there... I told you that those ponies get some of their memories wiped... And I don't want to share you with some mutant blue freak!"

[Lusterless Nova]

Since everypony is safe i guess we can leave right?

[PrincessButton]

Lary gets up and hugs Moonbeam tightly. "It was still dangerous in there... I told you that those ponies get some of their memories wiped... And I don't want to share you with some mutant blue freak!"

"I'm still blue, you don't mind that, do you?" She giggled and hugged back.

Since everypony is safe i guess we can leave right?

"Sounds like a plan to me.." 

[Lary]

Lary looked at Moonbeam with relief. "You're still you. And don't worry about Faith. She'll be fine outside of a small memory wipe. And all those ponies will have personalized rooms added to that horrid mansion... I swear, that blue thing acts just like a child."

[PrincessButton]

"I wanna get my flank out of this place, but I also wanted to solve the mystery.." 

[Lary]

"Yeah, let's not go back in there. Don't worry about it. I've been through that place twice myself. Nothing to be solved except the mutant acts like a baby.

Get on my back. I'll take us home."

[PrincessButton]

"Why did I never hear about you coming here..?" 

[Lary]

"It changes location every time, and I've ran into it a few times a long time ago. But the first time I saw it, it was nothing but that old building. That mansion was built off captured ponies. Every room in that house represented one."

[PrincessButton]

"Creepy..." 

[Lary]

"Well, I'm just glad you made it out alright. How many of you went in, anyway?"

[Lusterless Nova]

Creepy but clever. No matter what spell this is it is like nothing i've seen. And i think we were almost 10. ((too lazy to check))
Oh! Do you know why it blocks magic and flight?
