Psi-grub
From Warhammer 40k - Lexicanum
Psi-grubs are Xenos parasites, that feed on psychic power.[1]
When they become bloated with the energies of the Warp, the Psi-grubs can then be used to fuel psychic abilities. However it is possible for the Psi-grubs to explode before they are used and damage anything that is around them.[1]
