The Time Authority is an autonomous and mysterious government agency that is directly under the command of the highest head of government. Only the king, the prime minister and very few people know. To get to other times, you need to pass through a gate guarded by a government patrol. Its purpose is to check and stop any intrusion into the past that affects our current life or the opposite, mostly using history for selfish purposes. To do this, patrols need to go past and prevent them from happening.
