The coffin was transported to the museum overnight, freshly removed from the ruins that week. They had been ordered to clean the muddy surface and polish it. The stone surface was sealed shut with large metal nails, and they couldn't help but wonder what was inside. Nearly a week passed before things began within the exhibit. People passing out or panicking when near the stone monolith. Cameras for the exhibit glitching or simply ceasing to work. They was instructed to open the coffin that night and they couldn't help but have some amount of hesitation. Its not like they had never seen a mummy before.
