Selphids are basically parasites, as they can't live on their own, but need to take over a body, which they can control freely. They are more commonly known as "The body snatchers of Baleros".
Background
A Selphid's true form consists of a dark green and yellow semi-fluid wriggling mass of tendrils, with orange blood. They infiltrate the stomach of a body, their tendrils stretching throughout the nervous system and wrapped around some of the organs. They can infiltrate the body of the living, talk with their host and control them forcefully if they want. But this process is permanently.
If the body they infiltrate is dead, it takes them some time to assume control of the new form, as they have to remove the blood and several organs. They can take on the attributes of their host as well. They rarely breath if they don't speak, and also blinked much less than normal people. When the body gets damaged, they have to change to a new one, as healing potions don’t work on dead flesh.
In dead humans bodies, the skin and the insides of the body becomes totally white, as they are bloodless.
Around 10,000 years ago the the Selphids of the Magus Kingdom of Azervrish, the last nation of the Selphid, enslaved any race they could find under the rule of a powerful [Archmage], until an alliance between various nations and their host slaves destroyed them.[1]
Culture
They have set the rule that no body they snatch is allowed to be alive.
