Raya-Thu, also known as the Thinker, is the Goddess of Psionics and Queen of the Gods. Said to be the most beautiful woman in the world, the Thinker is the twin sister of Shami. She is married to Alurt.

The Thinker was driven mad after stealing Aex' eyes, according to the legend because she was jealous of Alurt's admiration for them. Through Aex' eyes, the Thinker saw things not intended for her to see, which drove her to madness. That madness in turn made her destroy Aex' eyes, leaving her blinded.

Priests of the Thinker concern themselves with the psionic community and often take up a place within councils and committees dedicated to psionics. They experiment on those who have lost their minds, seeking to understand their Goddess through their madness.

The Thinker is often asked for favours by those who feel great anger or who are struck by guilt or great loss, as she may offer comfort.
