Darkstalker Kaathe is a Character in Dark Souls. He is a Primordial Serpent, just like Kingseeker Frampt. He is the Leader of the Darkwraith covenant, who Tempted the Four Kings with the power of Life Drain which led to the eventual flooding of New Londo.
- Note: Darkstalker Kaathe will not show up if you went with Frampt and placed the Lordvessel.
- If you have obtained the Lordvessel, you can go to New Londo Ruins and talk to Ingward. Ingward will give you a key that' will eventually lead to the Four Kings boss (requires you defeat Great Grey Wolf Sif first to be able to walk The Abyss.) After defeating the Four Kings, Darkstalker Kaathe will appear in The Abyss. He allows you to join the Darkwraith Covenant.
- If you have not obtained the Lordvessel yet, you can kill Ingward instead to get the key, however be sure to buy his Cure Curse spell beforehand.
