Hi there! Welcome to my brief break down of "Wtf is Lahabrea" Part One! Fear not, I won't bore you with needless crazy FFXIV terminologies.

The Ancients are an extinct race of progenitor humanoids in the story, known for their vast scientific and technological advancements along with their uncanny ability to wield and manipulate aether (it's a source of life and magic, aka mana). Hephaistos is one such being and he works as apart of the governing body of that world known as the Convocation of the Fourteen. Lahabrea isn't his name but rather his "title" on this council.

Fast forward, Hephaistos had a wife named Athena who was the former Chief of Pandaemonium--this spooky research facility/prison where they studied mythic beasts and creations alike while imprisoning those they deemed unfit for their world. Athena was also a famous researcher and she found a magical black stone that wasn't from their world. The more she studied the stone, the more she unlocked the secrets of the cosmos. However, Athena went mad during her quest of knowledge and tired to use their son, Erichthonios, as living sacrifice in order to become a God.

Riveting, no? That's the gist of his character without going too deep into the lore or spoilers!
