A Mana Catalyst that allows the psyche plane interactions through a Psyche Node it is connected to. Mostly can be seen used for the psyche magic
Brain
By some reasion all the Deus-created dimensions contain almost exclusively only living creatures with their brain as a psyche catalyst. The more developed intellectually they are the better connection it allows.
Power
The catalyst powers can greatly vary depending on many factors.
If catalyst is biological, then potential of it mostly will be defined by the body of the owner. (brain capabilities, race etc)
Catalyst Destruction
When the catalyst is destroyed the Psyche Node stays in the plane despite wishes of the owner and their physical body's status in inactive status, so consciousness does not work and just "freezes".
