The Duke:
The Duke has enjoyed the strange treasure at some point even trying to lick if to see how it tastes. When its cold it should taste like icecream!
When The Duke tastes the ball of ice that looks like stone, he finds that it tastes like fresh basil.
But that was on the way to the mountains. By the time the expedition party reaches the mountains, the ball
feels like it's just that, a ball of inflated rubber.
Looks like a ball of rainbow-colored yarn, though.
Smells like woodsmoke.
...It's making a sort of very quiet powered-on-electronics hum.
