They have one thing in common: both dramas have a mother that, after losing her son (for different reasons), take care of another child raising him as her own.

Even if the plots and the main characters are different, some characters appear in both dramas (in Faith they're young, while in The Great Seer they're older).
In both dramas there are supernatural powers (used to fight and to time-travel in the first, used for divination/geomancy in the second).

Both dramas tells the story of how General Yi Dan (Yi Seong Gye) became ruler of newly form country, Joseon. The Great Seer focus more on the changes that lead up to the origins of Joseon. The Six Flying Dragons focus on how General Yi Dan who is crowned King Taejo shaped and molded Joseon with the help of his son, Yi Bang Won and trusted friend, Jung Do Jeon.
