TADA. You use your super tactile skills and discover a Wall of Force before you run into it. Before you can think, a Sphinx on the other side of the wall tells you to answer a riddle before you can pass. ~ "If a Phostwood tree falls in the Vesve and no one is there to hear it, does it make a sound?" ~ A) This is not a riddle. B) It depends... C) I don't know.
