Tablet of Ahkmenrah

The Tablet of Ahkmenrah was Ahkmenrah's most prized possession. It was given to him by his father. In the 1950s, the Museum acquired the tablet from the temple of the Pharoah. The tablet has the power to bring all of the exhibits, whether human or animal, to life during the night, but they must return to their places at sunup. Anyone or anything who is outside of the Museum after the sun rises will turn to dust. It's one of the night watchman's duties to make sure that no one (or thing) gets in or out of the Museum. In the sequel, it is revealed reviving dead or inanimate objects is one of the tablet's powers and can be used to open a Gateway to the Underworld since its secondary function is a keypad.

Night at the Museum

In the first film, Teddy Roosevelt shows Larry the tablet on his first night as a night guard. He explains to Larry that it has made everything in the museum come to life every night ever since it was placed there. Nights later, Larry shows his son, Nick, the museum at night and how everything comes to life, but nothings happens. Larry then finds out that the tablet has been stolen by Cecil and the other guards and rushes off with Nick to retrieve it.

Night at the Museum: Battle of the Smithsonian

Two years later, many of the exhibits are being shipped to the Smithsonian as archives as the museum being upgraded by holograms of them. Dexter secretly takes the tablet with them, not wanting to be a nonliving museum archive exhibit. As a result, the tablet brings the entire Smithsonian Museum to life. Larry travels to D.C. to retrieve the tablet and does battle with Ahkmenrah's older brother, Kamunrah.
