Changelings

Changelings are rather common shapeshifters from a distant planet called X43. They usually take the form of someone special to them but with a white, papery skin tone, in part for community with other changelings and in part because of cultural norms around copying the face of someone you love. They are known as rogues but also have an artistic talent seen throughout the 'verse.

Members of the Arts

There are a number of Changelings who perform as “The Artistry” with music and plays, using their dexterity to pluck strings, and their shapeshifting for acting portrayals. While they are rather well-liked as musicians, their face changing ability speaks to the people as dark Magic, a sinister power capable of the most masterful robberies and the most ingenious crimes.
They have plenty of reason to be scared as well. While not nearly as visually organized, many groups of changelings do use their abilities for crime. They follow The Listener in the Dark, goddess of song and murder, believing that true art comes just as much from loss as from gain. Some use the diety as a way to justify their own criminal activities or to provide reasoning to convince other changelings into doing terrible things.

Ancient History

The changelings are a very long lasting race and a race with a very limited historical memory of the period. Supposedly, they have gone through many forms through history, some with different senses and some adapting to unusual environments, leading to this development.
Whatever the case, much of their history was spent enslaved by other races. In the modern day, they are no longer enslaved almost at all. No new changeling slaves have been seen in hundreds of years, but their culture still has a long-lasting role confusion of seperation between self-view and culture-view that is yet to be broken down.

DND Mechanics

• Ability Score Increase. Your Charisma score increases by 2. In addition, one other ability score of your choice increases by 1.
• Age. Changelings mature slightly faster than Humans but share a similar lifespan — typically a century or less. While a changeling can transform to conceal their age, the effects of aging affect them similarly to Humans.
• Size. In their natural humanoid forms, changelings average between 5 to 6 feet in height, with a slender build. Your size is Medium.
• Speed. Your base walking speed is 30 feet.
• Shapechanger. As an action, you can change your appearance and your voice. You determine the specifics of the changes, including your coloration, hair length, and sex. You can also adjust your height and weight, but not so much that your size changes. You can make yourself appear as a member of another race, though none of your game statistics change. You can't duplicate the appearance of a creature you've never seen, and you must adopt a form that has the same basic arrangement of limbs that you have. Your clothing and equipment aren't changed by this trait. You stay in the new form until you use an action to revert to your true form or until you die.
• The Arts. You gain proficiency with one instrument of your choice and either the poisoner’s kit or the disguise kit.
• Alien Psychology. You have advantage on checks and saving throws to resist effects that detect your thoughts, emotions, or compel you to tell the truth. Additionally, you can present false thoughts, emotions, or lies as if you are being truthful by making a Charisma (Deception) check contested by the Wisdom (Insight) check.
• Languages. You can speak, read, and write Common and two other languages of your choice.
