Unreliable Proof

Exploration Stage: Burned-out Estate
From: Eli Montague
Description: Do you understand what this means? If the Keepers’ name was originally in the wax certificate, then they are the keepers of fire! And the fires started when strangers came to the house! I need to confirm my guess. Now, if only we could find a seal from the certificate... Can you help?
Completed: Bingo! The seal bears the same symbol as the bellows and the matches! And on the back it has remnants of the same twine as on the certificate. How touching: someone hanged it on a bracelet, as if for a keepsake... Probably after the crooks broke it.
