Phosforien is one of the 5 unmapped stars. Its light is described as being swirly and opalescent, and the Black Swan used it to light leap Sophie and Keefe to an empty section of tundra where a bottle of Elementine's light waited for them. Sophie described the leap as "a non-stop rollercoaster of spinning and dipping and swerving"[1], and the leap made her feel extremely nauseous.
