Slave Knight Gael is the final boss of The Ringed City DLC and a pivotal figure in the lore of Dark Souls III. Gael's journey is one of an unending quest for the Dark Soul, a pursuit that has spanned countless ages and driven him to the very end of the world. He is a knight who has served many masters, always seeking to fulfill his purpose, no matter the cost. His lore is deeply connected to the pigment of the Dark Soul, which he seeks to gather for the Lady of the Pygmy Lords, a mysterious entity residing in the Ringed City.
Throughout his long existence, Gael has consumed fragments of the Dark Soul, growing in power and becoming increasingly corrupted by its influence. This transformation is evident in his appearance and his combat style, which becomes more frenzied and desperate as the fight progresses. The battle against Gael is a multi-stage epic, reflecting his long and arduous journey. Initially, he wields a massive greatsword with surprising agility, but as the fight wears on, he gains access to the power of the Dark Soul itself, unleashing devastating ranged attacks and becoming a truly terrifying opponent.
Gael's ultimate goal is to provide the pigment of the Dark Soul to the Lady of the Pygmy Lords, who intends to use it to create a new world, free from the cycle of linking the fire. This ambition, born from a desire to escape the fate of the current age, highlights the complex and often morally ambiguous nature of the characters within the Dark Souls universe. His lore serves as a tragic testament to the enduring power of the Dark Soul and the lengths to which beings will go to achieve their ultimate desires, even if it means succumbing to the very darkness they seek to control.
