Astronomer Abracadabra

Exploration Stage: Observatory
From: Isabelle
Description: What a disorganized string of letters. It's as if they are dancing around under the spell of "Abracadabra". This could be another shift cipher. Maybe we can crack it using a cipher ring with two strings in a row. Find the cipher ring at the observatory. With it, we can break the astronomer's code. It would also explain why he didn't call for help when Helen was in such a state.
Completed: Look, this "code ring" has symbols on the back. It looks like the astronomers moved the letters five places to the right. That should solve the cipher.
