Warehouse Chief Croop:
Ah, it's as if you already know what's happening here! Good! Now we just have to figure out how you can help us.
We sent a Nebulite Orb to the Ivory Tower some time ago. They were supposed to send us word when it was delivered, but we haven't heard a thing. I can't spare anyone to find out what's happened. Will you confirm the delivery for us? You don't have to go yourself. Just send one of your followers to Warehouse Freightman Marty on the first basement of the Ivory Tower.
