Aetheric Throw (Ex)

An yllosan can enfold a nearby unattended object (maximum 35 pounds) and telekinetically hurl it as a ranged attack.

If the attack hits, the target and the thrown object each take 4d6+7 points of damage; the thrown object deals bludgeoning, piercing, or slashing damage, as appropriate to the type of object thrown.

The item’s composition or magical properties do not affect the damage it deals when thrown wrapped in aether. An alchemical weapon, grenade, or similar item thrown at a target using this ability requires a ranged attack rather than a ranged touch attack; however, if the attack hits and the item is shattered on impact, the target is affected by contents of the alchemical weapon or detonation of the grenade as the aether sheath dissolves upon impact. This ability is equivalent to the telekinetic blast of a 7thlevel aether kineticist for all purposes.

Starflight (Ex)

While incorporeal, an yllosan can travel through the void of outer space at an incredible speed. Although exact travel times vary, a trip within a single solar system can take 3d20 hours, while a trip beyond should take 3d20 days (or more, at the GM’s discretion)-provided the yllosan knows the way to its destination.

Telekinetic Invisibility (Ex)

An yllosan’s body bends light and weaves aether while dampening sound waves. This works as invisibility except that the aetheric bending is easier to notice than normal invisibility, so its bonus on Stealth checks is halved (+10 while moving and +20 while perfectly still). The dampened sound allows it to avoid automatic detection via sound-based blindsense and blindsight, but it does not gain any bonus on Stealth checks from this ability against a creature with such abilities. This is considered a natural invisibility effect and is thus not subject to effects such as invisibility purge.

Vulnerable to Sonic (Ex)

An yllosan suffers an additional 50% damage from sonic energy attacks. In addition, if caught within a sustained sonic effect which deals 5 or more points of damage per round, it cannot attack and can take only a single move or standard action.

An yllosan that is possessing a creature using greater possession or riding possession is not harmed by sonic effects, but if it is struck by a shout or greater shout spell (or any sonic effect that deals 15 or more points of damage) while possessing a creature, the yllosan is driven out of its host automatically and staggered for 2d4 rounds.

Organization solitary, pair, or cluster (3-6)

A powerful telepathic and telekinetic species-and the consummate spies-the yllosan (ee-LOE-san) are mysterious ghostlike beings that exist in a realm of pure thought, floating intangible through the material world of others.

They communicate by telepathy and revel in infiltration of other societies, extending their incorporeal tentacles into the mind and heart of creatures they meet to walk among them and search for those of good heart to offer advice or warning about evils in their midst or coming soon. An yllosan may step into the body of a creature to help it achieve a goal or task it fears to attempt on its own.

Yllosan are emissaries of hope and inspiration, but rarely stay too long in one place or within one body. They see themselves as advisors and helpers; it is not their place to do too much for those they meet, but to motivate them to rise up and face new challenges, daring to find the greatness within themselves.

Yllosan rarely reveal their true form to other races, preferring to work through possessed proxies while remaining in the shadows themselves.

Yllosan have long cultivated a reputation among the enemies as master spies and tireless investigators, and they enjoy the paranoia they engender in their foes. They are not above simply playing pranks on enemies while walking secretly among them, moving small objects around and using its suggestion and possession abilities to cause enemies to perform incriminating acts that cause their erstwhile allies to turn on them. Their presence is difficult to detect, as they can erase the memories of creatures they have inhabited upon departing their minds.

The yllosan are allies of the elali, but their numbers are dwindling. While able to pass through the void of space on waves of thought, the Ultari Hegemony has become more cunning at rooting them out and cutting them down after they have been expelled from a possessed creature. Some yllosan have abandoned the Accord and seek to preserve their species, including a colony of over 400 remain on a crossroads world.

This eldritch entity manifests as a god-like bluish light to the rest of the clergy, or it possesses one of the monks in order to speak face-to-face with new initiates or those who visit the chapel. Many non-yllosan visit and worship in this temple, unaware of the mysterious thought-creatures gathering within its walls and presuming the disembodied voices in their mind are numinous contact with a divine being or that the educated monks instructing them are actually the yllosan possessing them and speaking through them.

Yllosan are 3 feet in length, though their dangling tendrils and the misty psychic shroud that surrounds them sometimes makes them appear larger. As creatures of pure thought, they are weightless and virtually impossible to detect while possessing another creature; however, they are visible to creatures able to see invisible when entering or departing a possessed target.
