Welcome to my lair child. What, did you really think to sneak into my abode and carry off my most prescious treasures unnoticed or unopposed? I should eat you for such larcenous thoughts, but that's not really my style. I could run you back out the door, naked and with your hide tanned, but that really wouldn't do me much good, you'd just come back and try again.

How about I make you a deal, I'll give you the single most valuable treasure that I have within my lair without a fight, but there's just one condition you must share it with the next hundred people that you come across. What do you think, a sack of gold? this precious sapphire? or the enchanted sword on the wrack along the wall? None of those have the value of what I'll give to you.
