Poltergeist: The Legacy - Season 1 - Eps 6: The Twelfth Cave
The Episode begins in the desert where a team of surveyors are digging in a cave. One of the men there finds a jar buried deep underground. He opens the jar and finds a scroll inside, he opens the scroll, and the writing on the scroll glows red. He seems to have become hypnotized by it. He then murders his two colleagues. In the Legacy House, Derek tells the team that an old friend, Randolph Hitchcock, wants to donate an ancient artefact to the Luna Foundation. He wants to meet Derek and the rest of the team that night. When Randolph arrives, Derek tells the other Legacy members that Randolph was once a member of the Legacy, but he was forced out years ago. Randolph gives Derek the jar from the desert. Derek opens the jar and takes out the scroll. Randolph wants Legacy to examine and preserve the scroll. On a dock, we see a man wearing a mask, holding a silver cross.
