Raia executed the last commands, feeling the change in the engine’s thrum as the Voidspear shifted course. She cued her coms. “All right, I’ve got good news and bad news.”

To understand the technomancer class, it is necessary to remember that Starfinder is set in a universe where magic is a real, known, fundamental force of the universe. Just as some scientists study physics, and some study chemistry, in Starfinder it is possible to apply the scientific method to the understanding and manipulation of magic itself. With that context set, let's see how the Starfinder Core Rulebook defines the class:

Raia Danviri was born and raised in the lashunta city-state of Komena, near the southern tip of the continent of Asana on Castrovel. Komena's proximity to the formian-inhabited continent of the Colonies has made it a center of military activity for millennia, but to the Danviris, it was a home filled with hope and promise. Raia's parents were diplomats, and devoted their lives to brokering a peace between the lashuntas and the formians, a goal that spanned decades. They taught their daughter the value of all sentient life, for even among creatures like the insectile formians, who were so unlike lashuntas and had been enemies for so long, one can find similarities like culture, society, and civilization. But even more important are the differences. The details that separate one species from another are not only what make them interesting, but also teach one new things, and inspire one to question and re-examine one's own assumptions and beliefs.
