You look at the empty block, but nothing seems to be unusual about it. When you tap it experimentally though, it sounds slightly hollow. It's hard to tell, though.
You climb up onto it so you can stomp it and hear better. Sure enough, when you stomp on it, it makes a definatly hollow sounding sound...
...and suddenly flares with light, as glowing violet runes apear all across it's surface. Startled, you lose your balance, and fall forwards, onto it, scraping your knee
slightly.
And then your skin begins to writhe, and your muscles twist. Suddenly your shirt bursts away as something swiftly grows from your back. Wonderingly you look
behind you, and see a great pair of wings. Yours...?!?
Your pants are also suddenly destroyed, as a muscular tail grows abruptly from your backside. You dazedly realize that it is yours as well...
Suddenly your fingers and toes begin to feel very odd... Looking at a finger, you see that you are growing long claws... You crouch down to examine your toes,
and see that the same thing is happening to them as well.
Suddenly the light from the glowing runes changes from violet to blue.
Your skin looks weird, bathed in blue light from the runes. You try to stand up and step down off of the block, but you can't seem to straighten up from your
crouch.
Your skin is definatly looking different now. No doubt about it, it's definatly more than just the strange lighting.
It's getting harder to move. You feel stiff all over, your new skin feels very leathery and thick.
And suddenly the light from the block stops, and the runes fade to invisibility. It is now a simple looking concrete block.
You can now hardly move at all. You pleadingly at the path you came down, but you can't seem to make your legs move to it. Or your arms.... Even your neck
now refuses to look away. You are locked in this position, atop the second block.
Now there are TWO gargoyles flanking the door.
One with a very surprised expression.
