1 Sometimes blue, sometimes weeping.Sometimes twinkle, sometimes beaming. Never indoors, but yet the ceiling.What am I?
2 I face my brother, he faces me. At our sides two more I see. Together we make room for thee. What am I?
3 Made of ten but two are we. Five apart and we are weak. Five together hovoc wreak. What am I?
4 Despised am I by knave and liar. After me the wise inquire. I rise above all death and fire. What am I?
5 Shapeless, I take shape. Unguarded, I escape. Death in excess, death with slake. What am I?
