Notes from author
The Darkwraiths initially were the knights of New Londo. But when the Four Kings fell into Dark, their followers did as well. However, New Londo was flooded to contain the Darkwraiths, and all other citizens were drowned with them, having three Sealers placed to guard the ruins until one came who could slay the Four Kings. When the Chosen Undead broke the seal and opened the flood gates, the Darkwraiths emerged once more. Using the Art of Lifedrain granted to them by Darkstalker Kaathe, they can suck out the Humanity of their victims using a grapple attack and can create a shield that is capable of blocking most damage from all manner of attacks.
