Lord Gwyn recognized the foresight of these four great leaders of New Londo, and granted them their ranks and fragments of his Lord Soul. Sadly, they fell into the Dark after a primordial serpent offered them the Art of Lifedrain.
At the center of the (previously) submerged New Londo Ruins. To get to this boss you must first drain the water in the New Londo Ruins and have the Covenant of Artorias ring equipped before dropping from the stairs past the Fog Gate.

|4, 015 each King (16, 061 total)
||5, 019 each King (20, 077 total)
You must have summoned her for the Moonlight Butterfly fight if you want to summon her here. Her Soul Sign is on the other side of a large pillar (to your right while facing the bridge to the Fog Gate).
Even though you are fighting "The Four Kings, " more than four total can spawn if you take too long.
Only four can spawn at a time, but additional Kings will continue to spawn regardless of how many you've already killed.
It is possible to complete the fight with less than four Kings spawning if you have a high enough damage output.
Be wary that if using the Lifehunt Scythe, the self bleed effect is multiplied during this boss fight, so that just two hits can take half your HP.
It's not possible to fight this boss before you have the Covenant of Artorias, because you will die when you jump to The Abyss without it. You must also wear the ring throughout the entire fight, removing it will kill you immediately, but once the boss is defeated it is no longer necessary.
If you die during the boss fight, getting back to The Abyss can be hard since there are no bonfires in New Londo Ruins. Once the water has been drained out, the quickest way to get to The Abyss from the Firelink Shrine bonfire is as follows:
Upon reaching the small square where the first two Ghosts appear, run past the stairs and drop into the shallow pool just behind them. Beware of the Darkwraith that will engage you shortly.
Note: If you have the Ring of Fog, it reduces the detection range of the Darkwraiths and the Mass of Souls (if you haven't killed it yet). The Hidden Body spell can prevent some from aggressing altogether. Ghosts are unaffected by either.
** a faster route to the abyss other than firelink shrine is to use the bonfire in the tunnel that connects darkroot basin and the lift to the gates of new londo. Take the lift, run across the bridge dodging drakes, and hang a hard left once inside. Take the lift up, then run up the steps to the first doorway. Walk out on the ledge and drop down to the floor below. You should be right in front of the fog gate to the abyss.
