Quill's ref sheet since "what the heck is a hippogriff?!"
Quillian is the oldest of six children of a pegasi dam and a griffon sire living in a sea-side village in Great Grifton. Her and her siblings are hybrids called Hippogriffs, which exhibit a mix of their parent's species' traits. Quillian is a strong flyer, and is omnivorous- consuming fish, small frogs and lizards, and various bugs as well as typical pony-fare.
She is on the pep-squad at Canterlot University, and also the school newspaper staff. Quillian is very social, and subconsciously watches those she is around very closely and is able to pick up on their emotional states through body language and other cues. She is very empathetic and displays natural "mimicking" behavior to a greater extent than most, making her seem prone to drastic mood swings. Those of an observant and pessimistic nature sometimes interpret the involuntary mimicking as a sign of insincerity, causing them to mistrust her (but Quillian can't help but to feel how those around her feel).
Emotions and the immediate situation impact her decisions more than long-term goals or needs. She's very loving and friendly, and quick to help someone in need. Her love of writing has helped her excel in school, but being from a small town in a different country, she can be dangerously optimistic and trusting.
