Everything

The necromancer using this ritual sends the dead to haunt the dreams of an enemy, using the ghosts to drive an opponent slowly insane. Once the ritual is cast, the vampire has no control over this power, except to stop it from continuing. The shape of the nightmares and

the images that assault the target are not under the control of the necromancer; they are under the control of the ghosts who actually do the haunting.

The necromancer uses his own blood and a personal possession of the target’s in this ritual. Once the item has been coated with blood, the vampire must burn the item, sending a ghostly icon of it to the Shadowlands both as an identifying badge and as a reward to the ghosts who agree to haunt the target. While the item burns, the necromancer (and assistants, if available) pound out a relentless beat on gigantic drums of human skin. The drums are inaudible in this realm but thunderous in the home of the dead. To silence the deafening drums, the ghosts resignedly agree to negotiate with the necromancer. They promise to send nightmares to the victim for as long as the vampire demands, in return for a favor. Their request normally runs along the lines of passing a message to a living relative or exacting revenge against someone who slighted them.
