Psionic mine
A psionic mine is a mine that contains a group of psykers that have been driven insane from poisonous vapour that has been pumped into the chamber and then hermetically sealed. Their combined death cry sends psionic ripples through the Warp.[1a]
It was employed by the Word Bearers' starship, the Furious Abyss during the start of the Horus Heresy.[1a][1b]
