The Mansion in the Woods (not a jump-in. link to sign-ups in topic)

((ha science. Tiger the rooms are rotted not the hallway. And everything is solid))

Something had changed in the stained glass if anypony felt like looking. It now was a perfect replica of the one they had seen in the foyer.

[InsaneMar]

Rigor looked at everything, how it all changed and out of the corner of her eye she glanced at the stained glass.  Freezing for a moment as she forced herself to look away.  Thinking to herself, I did not just seen it had changed, it didn't change.  That is impossible.

[Tiger]

((Ah...))

Putting Flame on the solid boards (And Moonlight presumably does the same), Tiger noticed Rigor in front of the stained glass, and Tiger went over to look at it. It, too, changed.

"I don't like this place. Let's go see some other hallway, huh?" Tiger said.

The clocktower rang 12 times. ((something special in the foyer! Just so we don't Leroy through important plot point))

[InsaneMar]

"The clock is moving backwards instead of forwards," Rigor muttered.  "Part of me thinks we should burn this place down, though I don't think that would save Ponyville."  She stood there for a while, taking a deep breath before turning from the stain-glass window, "I'm going to check on that clock to see if I can either turn it off or fix it."

[Tiger]

"Right... I'm going to try find a lighter." Tiger checked the drawers of the rooms.

[InsaneMar]

Rigor sighed and walked down the hall towards the foyer, standing on the balcony as she looked around the foyer.  Being careful as she moved, she tried to look at everything before heading down the stairs.

Tiger found nothing.

The moon shone through the stained glass in the foyer, casting an eerie light on the floor. The window showed what had been in the hallway only the tree had become a large black smudge. The candles were still lit.

[InsaneMar]

"Oh great.. it's the moon instead of the strange sunshine.  Well at least you decide to make sense today," she muttered to nopony at all as she walked towards the window.  Looking at the strange smudge on it, "Mmm.. what is that?"

[Tiger]

Tiger flew over and rubbed at the black smudge with a stick

[rhyme writer]

((tiger, when did you leave the hall?))As she stared, the smudge seemed to almost move. Then it became a tree again. But something fell from the window. Another letter.

"If you are reading this, then I have failed. I attachted this note to the creature in hopes that somepony might finally destroy it. It feeds on fear and darkness, growing stronger as it feeds. It grows weak without fear so I tried to imprison it in this house. I hoped it would starve without a living soul to fear it. There is another way to stop it"

The end of the paper is missing.

[InsaneMar]

Rigor blinked and backed up as something fell, she stared at the tree before looking down at the letter.  She sat down and picked it up with her hooves, reading it carefully.  Turning it over as she sighed, "Of course it's never that easy."  She tried to think how it could have been attached to the creature, she didn't want to think about it because it poked holes in her science theory.  "So.. it feeds off fear and darkness.  Considering it's night and everypony here is obviously frightened it must be having a buffet right now," she sighed and put the letter in her saddle bag along with the other one.

[Tiger]

((Oh, um... When you weren't looking?

...I'm just a dodo  ))

Tiger noticed Rigor put something in her bag, and trotted over. "Hey, what was that? Lemme see!"

[InsaneMar]

"Didn't you read it?" she sighed, "Fine but be careful, I don't know how old these are and I'm trying to make sure they don't get destroyed."  She pulled the letter back out so the pony could read it.

[Tiger]

"Yeah, sure." Tiger read it, careful not to tear the weak paper apart. "So if this thing feeds on darkness, we just gotta light the whole place up, right? To get rid of half the things it eats," Tiger says as she gives the letter back to Rigor.

A pony shaped figure is seen in the distance
This mansion is huge... And so dark... And I thought I could see through the dark, this is really strange...

[rhyme writer]

As Tiger read, Rigor would be able to see a filly dressed in red standing some distance behind Tiger. She silently giggled and then simply wasn't there.

(dark, you are already inside. Everypony is part of the exploration team.)

[InsaneMar]

Rigor stared behind Tiger, looking where the little filly was.  She was frozen and took the letter automatically, not even realizing it was in her hoof.

[Tiger]

A pony shaped figure is seen in the distance

Tiger noticed the figure and shone her flashlight at it. "Who's there!"

(meh this topic needs a bit of a kick in the right direction. Too much ADHD and for once itbsnt me no offense.)
The double doors in the rear slammed open and a filly in a white dress stood in the door way. She looked kinda familiar if anypony thought about it a bit.
