Due to the meddlings of Professor Chronos and his time machine, the very reality of the universe is threatened. He has brought back a number of artifacts from different periods of history and stored them in his time lab. During one of these temporal shopping sprees, the time machine exploded, scattering its component parts throughout the centuries. Because of this, the universe has now started to rotate about its fifth axis, making the present less probable with each passing moment. Someone needs to return all the artifacts and recover the time machine before everything literally ceases to exist. That someone is you.
