Supermassive Singularity

Waves of gravity pull towards the ball of silver light that hovers before you like a miniature star, with a distorted yet vaguely humanoid silhouette within it.

Electromagnetic Shielding (Ex)

A supermassive singularity bends the electromagnetic fields around themselves to gain a deflection bonus to AC that is equal to its Charisma bonus.

Gravity Mastery (Su)

A supermassive singularity never takes penalties from gravity effects. In addition, a supermassive singularity can use their gravity sphere, gravity well, or reverse gravity spell-like ability as a swift action rather than a standard action. Alternatively, 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 or immediate action.

Radio Communications (Ex)

Due to their ability to monitor radio waves, supermassive singularities can usually understand and communicate in any language that is commonly transmitted through their territory. However, they transmit radio waves instead of speaking verbally so the other party wishing to communicate must have a similar ability or a communications device capable of doing so.

Slow Aura (Ex)

Creatures moving within 10 feet of a supermassive singularity become slowed as the spell unless they succeed on a DC 31 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. The save DC is Constitution-based.

Ultradense (Ex)

A supermassive singularity’s damage reduction cannot be bypassed by anything other than magical adamantine weapons. Abilities that normally bypass damage reduction, such as a paladin’s smite evil or a mythic champion’s fleet charge ability, do not overcome its damage reduction, nor do magical weapons with a high enhancement bonus. In addition, its incredible mass grants it a +20 bonus to its CMD 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 touch attacks 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 or gold. The singularity may choose for these rays to be visible or invisible, with the following effects: Visible rays are accompanied by dazzling stellar radiance, blinding the target for 1 round (DC 31 Reflex partial). Creatures succeeding on their saving throw 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.

Invisible x-ray pulses do not blind or dazzle targets; however, creatures unable to see invisible creatures or objects are denied their Dexterity bonus to AC against them.

Born in the heart of a supernova, sometimes the formation of a neutron star is accompanied by the birth of a kindred f e y spirit. Supermassive singularities, also called living singularities or neutron star fairies 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.

A supermassive singularity is less than 1 foot tall but weighs thousands of tons. On planetary surfaces and in areas where loose debris is abundant, it selectively warps gravity around itself so that its footfall does not shatter the ground underfoot or draw unwanted items towards itself. In open space, it sometimes amuses it to allow asteroids and plumes of space dust to trail in its wake.
