She is nice, but is often pesimistic. She is very smart. She is also VERY sarcastic.
Her pet is a bloodland pony named Harmony
She lives with her father and normie mother in what Darcy calls a 'cave'. ("It's not really a cave, it's just really unadvanced technologly) She gets along with her mother better than her father because she blames him for her chaos-bringing trait. ("Well it's true!)
She is BFFs with Fantina Bride and Rose Golem. (Both Pineapple Party's) Rose is the optimistic one of the group, but has a HUGE secret. (Yes, I used bold and italic, BECAUSE I'M AWESOME!) Fantina is very quiet, but more social than her younger cousin, Shade Darkness. (Also Pineapple Party's)
She is dating Mason Manticore. Him being optimistic and her being pesimistic it is a really good example of opposites attract. They are both interested in the arts.
