All Non-Hominids Are Psykers

anthropomorphous adjective. Shaped like a human being.

I have been giving thought to defining the Rhydin solar system. As Rhydin is a cross-genre campaign world, its solar system is likewise. So science fantasy. I am starting my definition from the science end of the spectrum (e.g., space is a vacuum) and “softening” the science with fantasy only as needed.

The first detail I am working out is how non-anthropomorphous aliens participate in a world adapted by hominids (e.g., humans, elves, dwarves, etc.) for themselves?

While fictional worlds may include non-anthropomorphous species, they are structured like the real world: reshaped by intelligent anthropomorphous beings for their own benefit. Hands with opposable thumbs begot tool use and the literal reshaping of the world. Speech communication via a voice box begot mutual understanding and information sharing from one person to many.

Fantasy worlds can utilize the mythological trope of magical animals that can talk and/or use human objects. Snakes do not have voice boxes, so sentient snakes cannot speak as hominids do. Spiders do not have hands, so sentient spiders cannot use hominid tools. How can either sentient species construct spaceships to travel into outer space?

They do have minds. They have psychic abilities inherent to the entire species. (Space magic.)

Telepathy need only be broadcasting to clone speech communication.

Telekinesis would need to clone both the physical strength of the hominid arm and the finely-controlled manual dexterity that fingers are capable of. Also needs the ability to manipulate two objects at once.

This line of thought means that psychic ability is nearly universal. Only in the anthropomorphous would it be optional—they are the exception to the rule.
