Consequently, his unyielding determination to win her love sets in motion a series of events that have far-reaching consequences, including jealousy, transformation, and conflict among the Tuatha Dé Danann.

Long ago, in the realm of the Tuatha Dé Danann, Etain, with her unparalleled beauty, had captured the hearts of many mortals and supernatural beings alike. Among her ardent admirers was Mider, the enigmatic lord of the Otherworld; consequently, he was captivated by her radiant charm.

Mider’s infatuation with Etain was boundless, and he spared no effort in his pursuit of her. He showered her with gifts, composed songs of love, and wove intricate spells to win her heart. However, Etain was already married to Midir, another member of the Tuatha Dé Danann.

Jealousy and tension brewed within the divine realm as Mider’s relentless advances continued. Consequently, the conflict escalated, leading to a supernatural duel between Mider and Midir. As a result, the two engaged in a battle of wits and magical prowess, each striving to claim Etain’s love.

In a stunning twist, Mider’s enchantments temporarily transformed Etain into a pool of water, a worm, and a beautiful butterfly. These metamorphoses were a testament to his magical abilities and, furthermore, his unyielding desire to possess her.

Time passed, and Etain longed for her mortal life and husband. Mider, moved by her yearning, used his powers to return her to the mortal realm, but with a cruel twist of fate. She was reborn as a mortal, with no memory of her past life.
