Puzzles Are Great. Let's Do All Of Them!

The ferry pulled up to a dock at the foot of a tall black mountain stretching into the sky higher than we could see. Built into, or perhaps just formed at the same time as the mountain itself, was a castle of the same obsidian stone. With no retreat available, we continued forward through a long hall lit by rows of torch holding statues. Purple flame cast eerie shadows around us.
 
We came to a wide courtyard. Though we were deep in the mountain, the ceiling above us was open to the sky. The room was a perfect circle and in the center a sculpture of a seven pointed star lay flat on a pedestal. Carved around it in a script impossible to describe but universally understandable was a verse describing the trapping of Uziel and the curse laid upon him. Uziel, trapped in his castle, unable to read the written word and discover the key to releasing him from his bonds. Also described were the instructions for opening the 7 locks.
 
Surrounding the 7 pointed star were 7 scenes, each containing a riddle. Solomon was understandably hesitant to undo the locks holding Uziel, but with no alternative, he relented and the troupe examined each of the 7 puzzles.
 
The first riddle came in the form of two birds, a hawk and a raven, each facing the other from their perch and chattering at each other. The same angelic script read "When is a raven like a dove like a hawk?"
