a skeleton stands in front of you, giving a monologue with sighs

Oh, don't stare. How would you look after aeons in some ghastly crypt? But your people are rather prone to death. Mine are not. And yet when I emerged from my completely unjustified imprisonment, I found them gone, our culture forgotten, any trace of the world I knew all but obliterated. I must even hide my true face beneath an ever-shifting mask for fear you savages will attack me! That is how I wander this strange world, trying to uncover the truth about a history you primitive people never even knew existed.
