"Hey, look at this!" exclaimed Gando, pointing at the nearby wall. As one of the near-to-the-ground members of the party (okay, short-arses), he had noticed a tiny button, inset into the wall near the ground beside the party. "What do you think it does?" he inquired.
"Press it!" declared the fearless Hawk.
"Umm…I don't know…" mumbled Iaido, who had been peering around the nearby area. "Do you reckon those holes do anything?"
Everyone looked to where the Samurai was now pointing - at a pair of large holes in the wall at the end of the corridor. "Bah. I bet they're just there for decoration or something." scoffed Hawk. "Go on, press the button - I'm sure it must hide some kind of very useful secret - surely!"
The rest of the party looked around, considering what they should do. "If someone presses that button and we get fried," said Sonja, darkly to Hawk, "I'll be blaming you."
So, what should the party do?
