Guriel
From Warhammer 40k - Lexicanum
Guriel was a Captain of the Flesh Tearers.[1]
Exhausted by the constant heavy losses and stubborn leadership of Gabriel Seth, Guriel conspired with the Inquisition to have his Chapter Master assassinated. To that end, Guriel trapped Gabriel Seth within a shrine with an Eversor Assassin. However, Seth was able to defeat the insane killer and escape the shrine. Afterwards, he tracked down and slew Guriel, who in his final breath proclaimed that others would come for Seth and for Sanguinius to forgive him.[1]
