True Light is a weapon of Xeno origin, made out of an unknown material appearing to be so dark, that it seems like there is an another room through it. It has a rare psionic feature, it is reactive to the wielder's psionic signature, and it can heat and radiate very high temperatures in the will of its wielder, allowing the material to be able to cut through creamite if it is shaped into a blade of any form.
It is given to the Punisher Priests of the Cult of the Punishers, upon the completion of their physical, Neuronic and psionic training, right before they are thrown into the Dark City of Commorragh.
