Tears to Tiara - S01

As the Holy Empire grows in power, the lands around it slowly come under its control. Eventually, the Empire's conquest reaches Erin, a small island where the Gael tribe lives. There, a priestess named Riannon is taken captive, meant to be sacrificed to the demon king Arawn, a sinister figure said to have caused great destruction long ago. Riannon's brother, First Warrior Arthur, saves her, and in that moment Arawn appears before them as a handsome man with grey hair. Keeping his true identity hidden and staying mysterious, Arawn offers his power and leadership to the tribe's cause and joins Arthur, Riannon, and their lively group of friends, including a skilled swordsman, a nimble hunter, and a band of gleeful pixies, as they fight back against the Empire and uncover the land's dark secrets along the way.
