Changeling

Every kingdom has changelings living within its confines, whether the public knows of them or not. Wherever changelings are, deceit follows, as they are hired to manipulate all sorts of politics, spreading false information and spying on the truth. Changelings know that others use them for ill-intentions, but changelings seldom care as they see this business as the most pragmatic approach to life, also understanding that they're truly outsiders to society, no matter how seamlessly they can blend in.

Appearance
Changelings in their true form appear almost like humans, except their skin and hair are ghostly white. A changeling's eyes are also completely white, except for their irises, which have pale blue or pink undertones. Changelings are rarely seen in their true forms, which they may leave mostly unkempt, and instead choose to adopt a persona, which might end up being someone they formerly knew such as a mentor or friend, or it might even be someone whose appearance they enjoyed and wish to mimic.

Some changelings, especially those who are at odds with the reality of who they are, will adopt multiple personas and use them as "masks", developing multiple personalities, names, and mannerisms for each one. These masks can help a changeling feel more comfortable about themselves, and it can even become beneficial for one who needs to conceal themselves from those who would wish to do them harm.
