Mind Swap Mastery (Su)

When a yithian casts mind swap, the duration is permanent (D). The yithian takes its senses and defensive abilities with it to a new body and doesn’t gain the awkward trait. In addition, when the yithian returns to its own body, the mind swap target must succeed at a DC 20 Will saving throw or forget being in the yithian’s body.


Environment any
Organization solitary, pair, or band (3–9)

In eons past, yithians inhabited a dying world. They used a desperate gambit to escape their planet’s doom: casting their minds through time and space. These errant souls came to rest in the bodies they possess today.

The minds that already inhabited these bodies were exiled back to the yithians’ doomed world, but what mattered to yithians was the survival of their species, so they had and have little concern for those exiles. Hounds of Tindalos hunt yithians, perhaps for this act, although yithians aren’t sure.

From their new home, the yithians created magitech that allowed them to contact minds on other planets and in other times. When the yithians found hospitable worlds, they created portals to those places.

Yithians retain a weaker version of their forebears’ ability to swap minds. With this power, along with the use of their hybrid portals and the immense psychic power of their elders, they travel between galactic locales. They often mind swap into other species to make use of starships, which they rarely build.

Yithian technology is akin to other high-tech equipment in the galaxy. They prefer electricity weapons. Some historians speculate that the storm coil is a yithian invention, although yithian versions are boxy and made for their physiology.

Yithians are about 10 feet tall and weigh nearly 2,000 pounds. They live for millennia.
