Shield

undefined:

A shield is a type of protector that will front with other headmates, whether it's a general purpose or a specific headmate, to hide and conceal their presence in front.

An example of this may be a protector-caretaker fronting with a little in a workplace setting, or a protector fronting with a specific headmate to keep others around the body from knowing they are in front.

A shield may also be considered a masker.

A shield is distinct from a prism or shell since they may only shield specific headmates, and they may not be hiding the system itself but merely the presence of a particular headmate.
