The Four Kings boss fight in Dark Souls takes place in the Abyss — a space of absolute dark accessible only after equipping the Covenant of Artorias ring, obtained from the wolf Sif, who guards Artorias’s grave. Without the ring, entering the Abyss triggers instant death. With it, you fall into nothing and fight ghosts of men who were once kings.
The Four Kings were the rulers of New Londo, a city that was sacrificed to contain the Darkwraiths — servants who had spread to humanity a technique for stealing Dark Souls. The Undead Township of New Londo was flooded by Ingward and two other sorcerers, drowning the population to contain the Darkwraiths before they could spread further. Everyone in New Londo died for containment.
The Kings themselves were corrupted by the Abyss before the flooding — given power by Primordial Serpent Kaathe, who wanted humanity’s dark nature to spread. The flood preserved the city, the Darkwraiths, and the Kings in the Abyss indefinitely. The fight is, mechanically, a race: the Kings spawn continuously if given time, overwhelming the player. The correct approach is aggressive enough to kill each fragment before the next appears.
Ingward, standing above the flooded city waiting for someone to drain it, has been there for ages. He has the key. He gives it when asked, without ceremony. He has been waiting to be relieved of his post for so long that the handoff is simply practical.
This is the kind of discovery that keeps communities alive for years. Well documented.
Really fascinating breakdown — I had no idea this was hidden in plain sight the whole time. Going back for another playthrough immediately.
