Human glamour of our divine trio. Of course the three don´t run around town as if they just stepped out of Anthrocon.
Glamour is a natural defense mechanism and doesn´t need any of the psychokinetic energy gods need to perform "miracles", so they can also use it in their depowered status. Since deities are a species of shape shifters, glamour was probaly evolved in an early stage of their evolution to protect them from predators when they were weak or defenseless.
