We're Trapped in the Past!

On a cold, rainy, August evening, you and a small group of history students are analyzing a set of ancient Egyptian hieroglyphs in the archives of their university. As you prepare to leave the archives for the night, you notice a strange light shining through the cracks of a closed door at the end of a dark hallway. Naturally curious, you and your friends set out to locate the source of the light. You open the door and are pulled through a portal to the past! You eventually regain your bearings and realize you and your friends have landed in the Hall of Mirrors in the Palace of Versailles at the time of its construction. You rush to a door at the end of the hallway only to realize it's locked! You notice 5 locks on the door. You have 45 minutes to open the locks and open your portal to the present, or you and your friends will remain trapped in the past!
