Roll the boulder
From Create Your Own Story
You heave the boulder over. It takes quite some effort. But then, you notice that the surface you've uncovered has some small indentations in it. You clear away the moss until you can see a few lines of a poem.
Two ways in, this cliff is cleft,
Of guidance is our Wizard bereft,
One leads to safety, the other to death,
When left with what's right,
Is it right what is left?
Do you:
Cast a spell!
