Game: Great minds think alike

As the group wanders the misty streets of Sigil, a strong wind suddenly comes up. The mist starts moving wildly, green waves dancing like incorporeal fairies...

Somewhere beyond their line of sight, the group hears a variety of voices, some incomprehensible, others in languages they know.

"Now what've the signers done now??"

"Damned powers... won't they STOP their experiments after they've failed?"

"Wonder if the factol's behind this..."

"Try green mist whether I should easy drink green tea is as to as."

"What the... it's sparkling? I hate sparkles."

"Blek."

Slowly, they see what is up: The mist around them begins to sparkle, soft, almost cautious, then stronger and stronger, until everyone has the feeling of suddenly entering a misty gemstone palace, sparkling and shining.

As Ophelia casts her Gust of Wind spell, the mist disappears around the group. Along with the mist, Ophelia sees three mephits who were just beyond her line of sight which are blown away by her magic, screaming in panic.

Curiously, despite the mist being blown away, the sparkling lights still hover through the air. A tiny sparkle floats right towards the Masked Gnoll, ceases its motion, and grows slightly. The ball of light - no more than a baby's thumb in size - transforms and shows a smiling face for the Masked Gnoll, then explodes in another five sparkles which then quickly disappear.

For a range of about 60 feet, the street is clear in front of the group, but the mist slowly returns to where it has been.

Naruk watches the sparkles with obvious fascination, then shakes his head and turns to Ian. "Yes, I'm all for using the bird now."

As Ohalian runs his chemical scanners, something unexpected happens: The results change constantly, as if the mist consisted of a matter which is instable at atomic level - or even beyond. What is astonishing about this is the fact that the mist didn't change in appearance or consistency.

So, Mr. Smith... now that we see what you see we'd like to know more about the man in leather. Can you show him to us?

The rest of the group sees how Ohalian points his finger at some invisible point left of him before he asks his question.

Where? There's nothing to see.

Gritham stays silent for a moment, then adds, Wait... there's an irregularity. Our engineers are on it.

[OOC: No, Ian still stands in front of the door, waiting for the rest of the group. The door can't be opened from the outside (at least, there's no obvious way to do that), there's just the rope for the bell, which Ian has not yet used.]

Ohalian pulls on the rope, and a beautiful bell sound appears. Only a second later, the door opens, giving free sight to a large entrance hall and a beautiful young girl, maybe 12 years old, dressed in an exquisite yellow and red ball gown. The gown fits perfectly to her vivid red curls which reach down to her hips.

The hall behind her is far larger than you expected - and actually larger than the house itself. This room which shouldn't fit into its building is roughly 200 feets wide and long, with dozens of doors and two enormous stair cases leading to an upper story seventy feet above the ground. The floor is made of large black and white tiles, like a chess board. Several chandeliers with a few dozen candles each bring light into the room - which, as you notice, doesn't have a single window.
This room alone is almost one and a half times as large as the mansion appeared from the outside.

The girl smiles friendly. "Welcome. The bird told of your coming. Enter and be my guests."
