During the Horus Heresy, N'Kari was one of many daemons summoned by Erebus, First Chaplain of the Word Bearers, by a dark ritual conducted during the Battle of Calth, presumably as a prelude to Horus's attack on the Imperial Palace during the Battle of Terra.
At some point, N'Kari battled the Eldar Phoenix Lord Asurmen. The mighty Daemon managed to slay the warrior, but in a rage the fellow Phoenix Lord of the Shining Spears Drastanta defeated N'Kari with his Celestial Lance, sending him back to the Warp.
In 800.M41, N'Kari and his Daemon followers found the derelict Craftworld Malan'tai and stalked its ruined halls for hidden caches of spirit stones to feed upon. For each spirit stone N'Kari devoured he grew more powerful, and by the time a Grey Knights strike force responded to a dire vision by their Prognosticars and arrived at the Craftworld, N'Kari had grown in strength tenfold.
The Grey Knights purged their way through the ruined halls of Malan'tai, led by Brother-Captain Pelenas and accompained by as many Purifiers as possible. Any and all Daemons standing before them were cut down, until the Grey Knight strike force cornered N'Kari in the despoiled Dome of Crystal Seers. A fierce battle ensued, wherein a dozen Purifiers were slain and Pelenas was struck down. But before the Keeper of Secrets could strike the killing blow against the Captain, Justicar Anval Thawn threw himself in front of Pelenas. With N'Kari's spear stuck deep in Thawn's flesh, the surviving Purifiers had enough of a respite to complete the ritual of Twelve Bloody Swords and successfully drain N'Kari of his stolen power, opening him up to be defeated by Pelenas.
In Codex: Chaos (2nd Edition), N'Kari is stated as a Daemon Prince of Slaanesh instead of a Keeper of Secrets. He was born on an isolated, backwater world which had been trapped in the centre of a violent warp storm for millennia, incidentally on the same backwater world as the Daemon Prince Bubonicus. The Chaos Powers had repeatedly attempted to conquer this planet, but had so far been foiled by the uncorrupted peoples of the world. N'Kari rose to prominence during one of the Chaos Powers' many attempts to conquer the planet. He proved himself a dedicated follower of Slaanesh in countless battles - and the debauched and disgusting revelries that followed them - and was rewarded by Slaanesh with the gift of Daemonhood. Along with Doombreed he was one of the two Daemon Princes that fought against the Emperor when he boarded Horus's battle barge, and he continues to serve his daemonic master to this day.
- N'Kari is also a major antagonist of William King's Warhammer Fantasy novel trilogy focusing on the High Elf twins Tyrion and Teclis.
