Magical Puzzle Lock
From Will of the Seven Campaign
Magical Puzzle Lock is a lock that protects the gate to Lord Aiden's Mansion.
There is a red gem at the center of this device. The lock is made of the same marble-like material as the obelisk.
The inside ring of the lock can be rotated to align the symbols on the outside ring. Both rings contain segments with ancient runes from the Paragon Alphabet.
To open the gate, one has to use the inner ring to spell the word "OPEN".
