You and your thread partner have found a dragon egg!

1. Unexpected treasure: You knew there was something in this box, but not that it was this...
   
2. Put that thing back or so help me! This is not what you signed up for. You would desperately like to get out of this game of very hot potato.
   
3. Hide it! Nefarious people are after the egg and you need to keep it from them.
   
4. Jackpot! You are nefarious people. This is great.
   
5. Sacred trust: You've been charged with this by someone or something.
   
6. Wildcard!
