Well, step one accomplished. You've come into a large tunnel, made of some undefinable substance. It is clearly translucent, and shimmers like the almost opalescent surface of a soap bubble. You lean forward, entranced by the strange wall. As your fingertips graze the slick surface, it ripples, like a pond, closing about your hand as you slide fingers through. As your arm vanishes through the other side into god knows where, a sharp crack thunders through the tunnel. To your horror, both ends are solidifying, and fast. You attempt to jerk your arm from the bubble-like wall, only to find it stuck fast. You'd better hurry, or your arm will be encased in solid stone! Well don't just stand there!! MOVE!!!
Keep Trying to Pull your Arm out
As you make your choice with haste, the faintest shiver of white appears from the shadows. Was that a face? Probably not. Better keep going.
