You are given an Alchemical Exaltation with an immunity to the negative effects of Clarity. You have the abilities of an Alchemical during starting character creation. As Alchemicals are constructs of clay and brass given life and a soul rather than born, your body will be transformed appropriately, but will still be considered both fully human and a living being for supernatural/metaphysical purposes.
You have Charms & Anima flares similar to a Solar Exalted - unlike most other Exalted, your Charms are not learned supernatural abilities, but instead magitech artifacts surgically implanted into special “Charm Slots” in your body, granting you greater versatility over other Exalted at the expense of only being able to use so many Charms at once. While you would normally require a facility known as a vats complex to install your Charms, as you are purchasing this power with SP, you can instead develop Charms directly from your body as you grow in power, similar to regrowing broken Charms, and store them by displacing them to Elsewhere.
As an Alchemical, you start out weaker than most other Exalted, roughly on par with Dragon-Blooded, but at certain thresholds of power, you can undergo a transformation into much greater forms; first into a Colossus, a great machine up to 30 feet tall capable of using stronger Charms more akin to siege weaponry than ordinary implants, and then eventually a Patropolis/Metropolis, an entire living city whose Municipal Charms can comprise entire buildings and infrastructural elements. While ascending to the rank of Patropolis/Metropolis would normally require a connection to Autocthon and His systems, you are free from such limitations, instead being able to undergo metamorphosis in any area sufficiently rich or ‘charged’ in supernatural energies and/or resources.
