Id/Fixspect

The Id is a very light and weak membrane that can change its shape and form around nearly anything. The purpose of the Id is to protect the Fixspect, which is similar to a Human consciousnesses.

The Id
After some time the person's form in question will regenerate, though depending on the damage done to the Fixspect and consciousness, the person may not be able to fully reform with their memories fully intact.

Despite this vulnerability, the Id has many more uses that make it arguably more viable than an Ego. Namely, the ability for the Id to stretch and morph allows it to be safely opened without any damage being done. This allows for individuals to experience Flow. In addition, this allows individuals to both Chain and Link with one another.

As well as all of that, due to Ids being entirely formless, they can and regularly do change. This is based off the will of the person, but as long as their Id is healthy they can completely change their form at any point.

Fixspect
A person's Fixspect is an object, normally something very important, that embodies the person's personality. Ids are meant to protect this item, however they aren't invincible. Enough damage will cause the Id to crack and rupture. This causes whatever form the Id was initially holding to burst apart, leaving the Fixspect as the only thing to defend the consciousness. Further damage from hear will deal irreversible damage to the person.

It's possible for the person to reform if their Id is strong enough. Depending on circumstance, and the stars, the Id may either grow stronger or weaker.
