Hall of Infinite Doors

Having absolutely no idea where the bridge is, or whether it exists for that matter, you turn and begin walking over to your right, alongside the deep, dark chasm. It isn't too long until you do see a bridge, a massive stone structure. As you get closer, you can see that there is a small man standing in the middle of it, leaning against the railing as if waiting for something. When he sees you, he stands up immediately and walks over to your end of the bridge. You can see that the small man only comes up to your chest. He has a very large nose, almost abnormally large, and his ears are pointed. A long, black beard reaches down to his stomach and large bushy eyebrows grow out of his forehead like weeds. The dwarf smiles.

"Hello lad. You care to cross this bridge?" the dwarf asks you.

"Yes." you start walking by him.

"I wouldn't do that if I were you," the dwarf threatens, "If you value your life."

"Are you threatening me?" you turn around to face the small man. You could take him.

"No lad, I be warning you." the dwarf says, "If you cross this bridge without answering my three questions correctly, you will surely die."

You sigh, "Are you going to toss me into the chasm if I ignore you?"

"No, but the bridge will." the dwarf snickers.

You pause. Could the dwarf be telling you the truth?
