Пророчество

In the infinite desert lies a kingdom called Oasis, which at the time is in great need. However, a prophecy says, "Once the key, in the form of a slave, and the lock unite together, redemption will be obtained, salvaging the kingdom." So they looked after it until they found Shen, marked with the symbol of the key. Zaphira, ruler of Oasis and sacred lock, can't wait to ( ͡° ͜ʖ ͡°)“conjoin“ with him, but will it work, or is the prophecy just a concoction?
