Albert Cragg's time cabinet was built in the 20th century by Albert Cragg himself. After numerous varyingly-successful tests, he took it to ancient Egypt, intent on stealing the legendary treasure of Tut-Am-Tut before it became lost to history; however, the dying Tut-Am-Tut ended up having as his last request that the cabinet be buried in his pyramid with him, stranding Cragg in the past.
