Tarik Torgaddon

Tarik Torgaddon was the Luna Wolves captain who could make the Mournival laugh without asking permission. Second Company, Horus's humour, Loken's better angel. Cthonia taught him the joke. The Crusade paid him to keep telling it in rooms that were getting darker.

Isstvan III was where Little Horus put a weapon through the punchline. Erebus scraped what remained into the daemon Tormageddon, which is a theologian's idea of recycling. A scrap of Tarik still found Garviel Loken on Luna later, enough of a ghost to warn a brother and not enough to stay.

He died a loyalist in a Legion that had already renamed itself. The laugh is what people remember, which is another way of saying they remember the moment it stopped.
