Changeling

Overview
Changelings, throughout the skeins of time, are nigh synonymous with deception, and warnings of betrayal. Called by many names, depending on their capabilities, Werewolf, Doppelganger, Skinchanger. In all cases, the stories warn that a changeling cannot be trusted, dropped off by their parents at birth to be raised in place of their real child, or any number of completely ridiculous statement.

Most of these are true. Changelings are an incredibly cautious race, and these capabilities serve them well. The ability to wear another race's skin, voice, and mannerisms grants them access to nearly anywhere, and in some cases, allows them to simply assume another creature's life. The boons of using this gift for evil are very difficult to resist. Some however, manage to use this gift for subtlety and misdirection for the betterment of ends greater then themselves, although these paragons of the Changeling race are few and far between.

By the time a Changeling is full grown, they will have settled on a preferred form for a preferred race and gender. Although in the case of most changelings, they dislike opting outside their genders, as keeping track of your true identity can already be difficult enough. the ability is entirely magical, and can only be detected by advanced scrying magics. The older the changeling, the more practiced their craft, and the more difficult they are to detect.

Changelings can always see through other changelings disguises, and will always know their true nature. In the interests of the Great Game, and keeping their own cover, however, most Changelings will avoid open confrontation on the issue.

Statistics
Changelings are incredible spies, and although they cannot emulate the physical or magical abilities of their hosts, they can often pull off completely accurate lookalikes, and as long as they aren't tested too thoroughly, it is not difficult to pose as someone for years at a time.Changelings size and shape varies, but their natural lifespans can be up to 120 years.

Advantages
Can take someone's place, with proper subtlety and activity. Make excellent spies or subversive agents.

Have the ability to mimic voices they have listened to for an extended period of time. ( A middle length conversation is enough to get someone's speech patterns down.)

Disadvantages
While unconscious (not sleeping), Changelings revert to their native form (Their base form, which is the preferred form they choose upon becoming an adult)

Presence in the Shatterstorms
Changelings, as omnipresent as they are, have inundated many cultures affected by the Shatterstorms. It was only an eventuality that some would end up in Fenestra. They have carried the Great Game with them. For non-changelings, seeing through their disguises is difficult, if not impossible. Their role in society is as silent watchers, serving their own ends. Anyone, anywhere could be a changeling. From your child to your best friend to your king. And with every Shatterstorm immigration, it's possible that a whole new bunch have immigrated. Watch your back.
