Intrashifter

What is an Intrashifter?
An intrashifter is an intrasomal shifter, meaning that they physically (-somal) shift on the inside (intra-). These shifts can be called intrasomal shifts, somatic shifts, or simply physical shifts.

Intrashifters have existed alongside pshifters for decades. There is the belief that intrashifters are the descendants of hybrids between human and shifter/were. Said hybrids stuck with certain groups amongst themselves and were known to hide easier.

What they do
Instead of their human body becoming nonhuman, the inside of their body (called "essence" since it makes up their functions) becomes nonhuman. Organs and energy that allows those organs to function change and morph, thus fitting what their inner-side would have on the inside.

Intrashifters are extremely common in society, most likely due to their ability to hide amongst others without their other-side being seen as nonhuman. Even so, they would be at risk of harm if their organs, blood, stamina, and brain are found out to be not human. Regular check ups are a problem since the exoform does not shield or hide them, and their bodies may be harder to treat for illness - as if they have abnormalities (ones that cannot be described as preexisting or common disorders or conditions).

When shifting, an intrashifter may appear to be in visible pain or reject familiar foods and drinks (said pain should not be from internal bleeding or organ failure - if so - it is not shifting). These pains, like hunger and instincts, come from the brain, which is also changing and shifting.

They have a higher affinity for phantom shifting and somatic shifting than others, and may prefer that over physical shifting.

Terminology
Human body - simply refers to the body in which is humanoid, not exactly the species.

Essence - organs and the energy that makes them function. Energy as in magickal, hormones, nutrients, and vitamins that may naturally occur in the environment/body.

Exoform - A metaphysical veil that contains the inner-side's essence, keeping a certain amount of energy from expending during shifting. Not magickal, not spiritual, but somaticaly perceived.

Other-side - A pshifter's real body/form. What the human body morphs into.

Inner-side - An intrashifter's real body/form. What the essence morphs into.
