The Emperor's Horn
THE PSYCHARUS WORM
Long before the coming of man, the Halo Stars and the Expanse were home to strange and terrible xeno empires. Occasionally, artefacts from these lost civilisations are found by traders, explorers and smugglers and filter back into the Imperium. The Psycharus Worm is one such device. Appearing like a tarnished brass maggot some six inches in length, the worm is cold and greasy to the touch and on first inspection appears to be nothing more than a macabre
curio. However, when linked to the warp it possesses a terrible intelligence and the power to animate the dead and the never-living into vile warp puppets.
