This Way Up

You take off, leaving your dreary thoughts behind. After a while, the slope turns into stairs, and a sign appears on a post.

-HOLD ON TO THE SAFETY RAIL
by order of the King Himself

You pay no mind, and rush on ahead. After what seems to be twenty or so flights of stairs, you begin to grow weary, and sit down on the steps. A rumbling, weak, but steadily growing stronger, meets your ears. Oh great, you think. What could it be this time? You stand up, and notice that there are no more stairs behind you. Looking down, you notice the stair you stand on shift down, then come free, sending you hurtling towards your death. Should have payed attention to the sign.
