How do you mean "affinities" here?Outsiders with affinities for evil fey works best for me.
SIZE: L (20. tall)
Mara are reputed to be 20 feet tall or more, gray-green in color, like weathered stone, and of hulking humanoid shape.
Mara communicate among themselves with bird-like cries, whistling, and calls. They can understand, and may respond to, simple mental commands.
The mara stoops to attack with rending claws and hooked beak. If both claws hit the same target, the bite hits automatically, inflicting double damage.
A mara can be affected by any weapon, but has a 25% resistance to magic.
Bright, direct sunlight immobilizes a mara’s body and renders it unfit for the mara’s spirit. This effectively defeats the creature, driving the spirit into painful exile on an outer plane. Many mara have been trapped by the sun, and their abandoned stone bodies form circles and groups of standing stones to this day. Magical and man-made light, such as fire or lantern light, have no effect on the mara, nor does light from such creatures as will o wisps.
