WBW: Jaehaerys the Guardian of the Faith of the 14 Flames Book 1

Hadrian stumbles into the World of Ice and Fire and changes how the Targaryens see their ancestral Faith. Chapter 1-9 cover Aegon's conquest, which Jaehaerys(Hadrian) aides with, but with limited magic due to the age he is in his own world. 10-15 are lacking Hadrian but cover time between his appearances in the world. Rated T for now
