One day, after returning to the Main Hall from adventuring and ordering a Volcanic Xorn, you turn around and see a strange man dressed all in black.
He bows low and says, "I come from the land of the Sister Mountains and I bear the startling news that you are the sixteenth in line for our throne."
He continues, "However, all heirs to our throne must perform a deed to prove their worthiness. The deed selected for you is to rid the countryside of a horrid warlord who calls himself 'Master'. He is said to live in a mountain not far from our villages. You journey at dawn." He then describes to you the location of the mountain.
You find the mountain, and when you reach it you see a spiral staircase into the side of the mountain. You climb up, but when you reach the top, the staircase disappears, which means no way out!
