I found the greatest riddle ever (credits to Ted-Ed), and I want to see if anyone can solve it without looking up the answer. THE RIDDLE OF THE ALIEN OVERLORDS. You and your team have crashed-landed on an ancient planet. The only way off is to appease its three alien overlords, TEE, EFF, and ARR, by giving them the correct artifacts. Unfortunately, you don't know who is who. From an inscription, you learn that you may ask three yes or no questions, each addresses to any one lord. Tee's answers are always true. Eff's answers are always false.  And Arr's answers are random. But, there's a problem. You've deciphered the language enough to ask any question, but you don't know which of the two words 'ozo' and 'ulu' means yes, and which means no. How can you still figure out which alien is which?

Fear: The Emotion of Death   You can't see me, But I'm there. I'm in your tears, I'm everywhere. I stalk you in your shadow, So stealthy and no slack. I'm made of dark matter, You better watch your back. You can hear me, I'm your beating heart. Inside is emptiness, Tearing you apart. You shiver and shake, At the sound of my name. I engulf you, drown you, Surround you with shame.   I've seen destruction, More than anyone. I'm darker than, The world with no sun. The agony arises, There's so much red. Most of it coming, From the dead. I become your shadow, I'm a terrible sight. And when you see me, You're frozen with fright. I'll grab you by your neck, You'll be thrashing around. You're crying, shrieking, Until there's no sound.   I feel so sad, So empty, so. . . Alone. So you'll feel the same, You'll be on your own. And as long as you are with me, At the point of no return. You will go crazy. You'll crash and burn.   Then you understand, With your slowing of breath. That I am Fear, The Emotion of Death.
