Unforeseeable Pyramid

You were asked to clean out the office of an archeology professor, Dr. Johnathan Bancroft, who has been mysteriously missing for over 10 years. As you were collecting books and research papers into cardboard boxes, you came across a peculiar looking journal belonging to the professor. You dusted it off and opened the journal to its last entry. It read; "It has been one week since my dear friend and colleague Professor Milligan left on an expedition to the newly discovered Egyptian pyramid. His research assistant returned 3 days ago without him, pale as a ghost, and claimed that he was instructed to watch the equipment outside of the pyramid, but then after about an hour, the assistant heard terrifying screams ... and then silence. I must find out what happened to Dr. Milligan." You and a group of adventurers decide to embark on a journey to the ancient pyramid to unravel the mystery of the missing professors.
