Plurality is the state of having multiple headmates collectively sharing a single body. The group of headmates is called a system.
Causes
Plurality has multiple causes. Examples include:
- Traumagenic systems, resulting from a traumatic event or post-traumatic stress.
- Systems created through tulpamancy or other explicit acts.
- Other causes, which can be grouped under the umbrella term endogenic.
- Mixed-origin systems, which have been created from a combination of causes.
Becoming plural can happen at any point in life.
