Editing DFRPG Ghosts:Echoes and Phantoms (section)

==Phantasmal Bodies==

Like other Ghosts, Phantoms are largely insubstantial and invisible to most of the living (the exceptions being animals, and those with certain supernatural senses, such as The Sight or Ghost Speaker).

Phantoms do not need to acknowledge mortals in order to interact with them.  Indeed, much to their regret, the opposite is true; most Phantoms find it difficult to get those without such senses to notice them at all.  Unfortunately, Phantoms must make themselves noticed by mortals (through nonmagical means), in order to affect the mortal world.

A scientist would compare them to quantum phenomena; unless observed, the waveform of their actions do not collapse into something measurable.  A Phantom could get into a bank vault with trivial ease, but they couldn't steal the cash unless someone else was in the vault to witness it, and the ghost could make their presence known to that person.

Some Phantoms can construct Ectoplasmic duplicates of their incorporeal appearance.  This allows them to interact with the physical world far more easily.  It is also known that a Ghost using a True Name immediately makes their presence known to the name's owner, and that they often know the True Name of the person responsible for their death, if they ever heard that person's True Name in life.
