Ras was found on a small island in The Firebird Atolls as a child and was adopted by the Azure Zenith.
Through her menagerie of imaginary and animal friends and the way nature seems to bend to her aid, it was quickly understood that she's a Seer.
Using her magic to predict storms and avoid other obstacles she became the ship’s lucky charm, and with that, and her later obtained knowledge in Alchemy, got her the official title of “the ship’s mage” (self-proclaimed and reluctantly recognized).
Since she was young, Ras has been a mischievous thing. She was often referred to as Rescal as she never told the crew her name. She later adopted it as a name, this was later shortened to Ras as a nickname because the more she grew up the more awkward it became.
