Far and away one of the most enigmatic of dragon breeds, the Sinomorph is shrouded in near-complete mystery. While the exact conditions that herald its arrival are not certain, it is said to only appear when called upon by all six Zyumorphs. Record of its existence may be limited to folklore and ancient legends, but recent sightings seem to suggest this storybook behemoth may truly walk the lands of Valkemare. If the stories of the past are to be trusted, its appearance serves as a beacon of light in the face of looming calamity.
Zero Cassia was the second member to join the "Zero Group", a group of Sinomorphs founded and led by Zero Sinaasappel, dedicated to letting zero bad things happen to the dragons in their realm. It is said that she has the power to make forests grow from formerly barren soil and to halt the spread of disease. She is very energetic and full of life.
