Cryptography Origins

From: Martha
Description: We managed to find keys for the various ciphers in the Observatory. Each of them is a hint to the Astronomer’s personal cipher. We’ve collected everything we need to get a Cryptographic Disk to help us decipher the Astronomer’s records. Bring me some artifacts. They help me focus and stop me missing anything.
Completed: The magical energy of the artifacts highlights the symbols on the Cryptographic Disk and they take on a different appearance, as new symbols appear on one of the disks. Bring me the notes, and I’ll read them.
