A sacred beast is a creature blessed by the divine that is descended from the guardian beasts.
Blessed by Gods. Sacred beasts are often kept by gods and celestials as prized beasts. They are typically found in the upper planes, but some have been transported to the Material Plane.
Noble Spirit. Each sacred beast traces its ancestry to a divine creature and retains some measure of nobility. Unlike mortal beasts, sacred beasts are neither aggressive nor afraid of humanoids. They will tend to go about their business unless disturbed, while observing any intruders.
