Welcome time traveler!
I am Chronos, Grand-master of Time. By entering my mind you have automatically volunteered to become a participant in my challenge.
I will be sending you into the past - it will be up to YOU to answer the 15 questions I ask, correctly.
If you answer them correctly, I will bring you back to the present and will make you historian with the rank of 'Initiate'.
If you fail, I will leave you in the time period where you failed to answer the question...stranded!
There is still time to back away NOW...or do you accept the challenge?
