The Room of the Tablets was an enormous underground stone "great hall", discovered in a top-secret Soviet digging project, headed by Dr. Gennadi Volodnikov in 1947, beneath the archeological site at the ruins of Babylon. The room was named this specifically by Volodnikov; it could only be accessed by what Indiana Jones, who infiltrated the room, considered the oldest elevator in human history, which used a weight to drop down into a long shaft from which a carved-out, alley-like path led into the room. The room, made entirely of mudbrick sandstone, rose up four or five stories high, with various large alcoves and huge shelves or, perhaps, galleries carved into one wall. A series of traps and obstacles (including spiked chamber walls and loose rock bridges) had been built into the room, in order to prevent thieves from stealing a set of four cuneiform tablets variously scattered throughout the room. Jones also discovered inside a secret chamber a winged statuette of Marduk. Jones referred to the room as "Nebuchadnezzar's Library" as a joke; however, upon collecting all four cuneiform tablets which interlocked into a single readable message, he discovered that, indeed, the room had belonged to the Babylonian king Nebuchadnezzar. The message made references to the fabled "Infernal Machine" and Jones roughly translated it aloud, "Make welcome seeker. Know that it was Nebuchadnezzar, in heed of the writing that Marduk made appear unto him, who builded the Great Engine. Having no understanding, the rabble hath thrown down his work, but four trusted disciples are scattered all over the Earth and the relics go with them. Wouldst thou tread the path of knowledge, look eastward. Urgon, it is, who flees to the heavenly mountains, where Shambala holds a mighty secret."
