Sephirot

Sephirot, the Fiend is a primal from Final Fantasy XIV, who appears in version 3.2, The Gears of Change. He is one of the three Warring Triad.

Story
Sephirot, The Fiend, was one of three Primals collectively known as The Warring Triad, who were summoned near the end of the Third Astral Era in order to repel the invasion of the Allagan Empire. Though powerful, they were eventually defeated and imprisoned in Azys Lla, where advanced Allagan technology was used to simultaneously drain their power while maintaining their physical forms. They remained suspended this way for centuries, until the actions of Archbishop Thordan VII weakened their seals, threatening to allow them to escape imprisonment.

Sephirot, a deity once worshiped by a tree-like race native to Meracydia, was the first of the Triad to risk breaking free of his restraints. Guided by Unukalhai, the Warrior of Light and Krile ventured to Containment Bay S1T7, in order to unseal and defeat Sephirot before he could escape containment and unleash unthinkable catastrophe.

After the group achieves victory, Unukalhai tells more of Sephirot's history, as related to him by his mysterious master. It was originally a sacred tree that was elevated to godhood by the belief of its worshipers. Among its many powers is the ability to induce growth in living organisms, including itself, which allows it to grow to enormous size during battle. Once the Allagans sealed the primal, they studied this ability and used it to create many of the bio-engineered monsters.

Unukalhai then presents the Warrior of Light with an Allagan tomestone that contains data on Sephirot as he existed during the Third Astral Era. Using the tomestone at a terminal in Azys Lla will create a simulation battle based on this data, allowing one to experience a fight against Sephirot at his full strength.

Creation and development
Sephirot and the other two deities of the Warring Triad were based on their Final Fantasy VI counterparts. Sephirot itself was inspired by the Fiend.

After the track was released along with version 3.2, the band leader Spider One posted on the band's official Facebook, criticizing the song creator that it is a straight up rip-off and not just using their song as an inspiration . Director Naoki Yoshida stated that he has been made aware of an allegation regarding similarities between these songs but the track plays in the second phase of Containment Bay S1T7 is just another song in the industrial rock genre which is a popular genre that can be further divided into numerous sub-genres and countless songs from these genres have been released worldwide. Composer Masayoshi Soken also stated to Yoshida that he was unaware of the track in question while working on this Final Fantasy XIV track.
