For centuries, the renowned Paradox University educated the best masters of time ever. This year, after the retirement of Master O'Clock, there is only one vacancy to occupy and our seniors will face a final exam in which they will have to prove who is the Master of Time. The challenge facing our students is known as Test of paradoxes. Each student is sent to a different moment in time and access to a time machine, so they can send travelers to their peers’ moment. But watch out, if the traveler finds himself in the same timeline a temporary paradox will occur and the thin fabric of time will be ripped apart. Create paradoxes on your piers’ timelines, avoid them in yours. Reveal yourself as a great Master of Time in Paradox University and relieve Master O'Clock. —description from the publisher
