Gravity Mastery (Su)

A supermassive singularity never takes penalties from gravity effects and warps gravity in such a way that it inflicts a 20% miss chance against all ranged attacks.

In addition, a supermassive singularity can use its control gravity and gravitational singularity spell-like abilities as a swift action rather than a standard action. Finally, if the supermassive singularity is targeted or would be in the area of a gravity-based spell or effect, it can negate that effect as a swift action or a reaction.

Slow Aura (Ex)

Creatures moving within 10 feet of a supermassive singularity become slowed as the spell unless they succeed on a DC 27 Fort save. The creature remains slowed as long as they remain with the area of the aura. A successful save renders the creature immune to the supermassive singularity’s aura for 24 hours.

Ultradense (Ex)

A supermassive singularity’s damage reduction cannot be bypassed by anything other than magical adamantine weapons. Abilities that normally allow a creature to bypass damage reduction do not overcome the singularity’s damage reduction. In addition, its incredible mass increases its effective KAC by +8 against combat maneuvers that attempt to move it.

X-Ray Pulses (Ex)

A supermassive singularity can emit concentrated pulses of x-rays as its primary form of attack. X-Ray pulses are ranged attacks targeting EAC with a range increment of 100 ft and are considered ray attacks. X-Rays can penetrate most materials, so cover bonuses to AC do not apply unless the cover is provided by a force effect or by an extremely dense metal, such as lead.

An x-ray pulse is accompanied by dazzling stellar radiance, blinding the target for 1 round.

Creatures succeeding on a DC 27 Reflex save are dazzled for 1 round instead. This duration stacks if a creature is struck by multiple pulses, and a creature already dazzled takes a –2 penalty on further saving throws to avoid blindness. If a creature successfully saves against some but not all pulses, the duration of the dazzled effect does not begin until after the target is no longer blinded.


Environment outer space
Organization solitary

Born in the heart of a supernova, sometimes the formation of a neutron star is accompanied by the birth of a kindred fey spirit. Supermassive singularities, also called living singularities by some races, appear as a glowing ball of silver light less than a meter across. Supermassive singularities can perceive and manipulate energy along a wide range of the electromagnetic spectrum allowing them to affect light, electricity, gravity, magnetic fields and even x-rays. Emitting deadly bursts of x-rays are the supermassive singularity’s primary means of defense, but other favorite tactics include slowing foes with gravity wells and disarming foes with ranged x-ray pulses within an active magnetic field.

While not always malicious, supermassive singularities have the arrogance typical of most powerful fey and they have absolutely no concern for the consequences their actions have on “lesser” mortal creatures that they encounter.

However, there is at least one account of a crew of shipwrecked survivors appeasing a supermassive singularity with lavish gifts in exchange for it using its interplanetary teleport ability to return them to an inhabited world.
