Ethereal
You exist on the Ethereal Plane. While on the Ethereal Plane, a creature is called ethereal. Unlike incorporeal creatures, ethereal creatures are not present on the Material Plane.
Ethereal creatures are invisible, inaudible, insubstantial, and scentless to creatures on the Material Plane. Even most magical attacks have no effect on them. See invisibility and true seeing reveal ethereal creatures.
An ethereal creature can't affect the Material Plane, not even magically. An ethereal creature, however, interacts with other ethereal creatures and objects the way material creatures interact with material creatures and objects.
Even if a creature on the Material Plane can see an ethereal creature the ethereal creature is on another plane. Only force effects can affect the ethereal creatures. If, on the other hand, both creatures are ethereal, they can affect each other normally.
