# Form shapeshifters

> How a shifted appearance is kept separate from a character's real biology.

How a shifted appearance is kept separate from a character's real biology, so a disguise can change what a character *appears* to be able to do without ever changing what their body actually produces or can conceive.

## What shifting does

A shapeshifting character can wear a body that looks and behaves differently from their true self. Their **appearance** decides what they can offer and receive in a scene — a character presenting as male can act the part, and a character presenting as female can be approached that way. Their **true body** still quietly decides what actually happens underneath:

* A character who *looks* male but is really female won't produce anything when reaching a climax as a male would.
* A character who *looks* female but is really male can still be approached as one, but nothing they receive that way can ever lead to a pregnancy — it simply passes through unnoticed.

This means a shapeshifter can wear a disguise convincingly during a scene without their body ever betraying — or fully committing to — the part they're playing.

## Building a disguise

Shapeshifters can pick up new forms by sampling certain fluids from other characters — a taste, a touch, or a stored sample — provided the source is a kind of character close enough to their own nature. Copying from a fluid also quietly carries a trace of that character's lineage, which can matter later for family and parentage questions.

## Things to keep in mind

* Fertility shown on a profile always reflects the true body, even while a disguise is worn.
* Devices that capture fluid samples will still run while worn, but won't collect anything a shifted body can't truly produce.
* A shifted character's displayed parentage and lineage follow the disguise, not the true self — that part of the cover story is intentional.
