With this baby, we can make any woman we desire our willing sex slave. And I know just where to start...
―Warren Mears[src]

The Cerebral Dampener was an artifact created by the Trio, empowered through a spell that involved the musk gland of a Homja-maleev Demon. When activated, the Dampener emitted a flash of light that took away the free will of the victim, making him or her submissive to the caster, which also became the subject of the victim's sexual desire. Wearing sunglasses, however, blocked the effects of the Dampener.

Warren Mears used the artifact on his ex-girlfriend, Katrina Silber, to transform her into his sexual slave. However, the effects of the Dampener were temporary, causing Katrina to break free of the spell before Warren could rape her. He tried to use the Dampener once again, but the artifact's power had worn down. As Katrina tried to escape the Trio's lair, Warren smashed a champagne bottle on the back of her head, killing her.
