Doctor Who and the (Demi)Goddess of the Moon

A long time ago, there were the Time Lords, a powerful species that isolated themselves from the rest of the universe, vowing never to interfere with the course of the timeline and prohibited leaving their homeworld, Gallifrey. That is until a renegade Time Lord known as "the Doctor" decides to steal a TARDIS and escape along with his granddaughter Susan, both out of a desire for adventure and to find a safer place where Susan could live. However, things don't go as quite as planned as the two do land in their destination - Earth - but instead of 20th century London, they arrive in 13th century Mexico.
