Solarian: Stellar Attunement

As a solarian, your existence cycles between the aspects of stars. You begin with two aspects: photon (the power of stars to emit heat, light, and plasma) and graviton (the power of stars to attract and imprison objects through gravity). At any time, you're considered graviton-attuned, photon-attuned, or unattuned. Many of your abilities have additional effects based on your current attunement, and some abilities swap your current state of attunement to another state. You gain the Attune action.
