Her official biography says: "A mysterious young astrologer who proclaims herself to be 'Astrologist Mona Megistus,' and who possesses abilities to match the title. Erudite, but prideful.
Though she is often strapped for cash and lives a life of thrift, she is resolved to never use astrology for profit... It is this very resolution that has caused her to constantly fret about money."
Mona is an intelligent, proud, and very passionate astrologist. In her original world, she was known to be knowledgeable and famous for her studies, columns, and presentations. Her ultimate dream is to surpass her Master and become the best astrologist there is.
Her unique ability is her mastery of hydromancy. By wielding water and observing its reflection, she can divine the fate of others and divulge information about them. However, she does not rely solely on this skill. Mona is startlingly perceptive without it and can tell at a glance whether someone has ill intentions.
She is terrible with finance. She'll spend any income she has on astrology equipment, texts, or apparatus, often leaving her broke and without shelter or food. In things related to money but not astrology-related, Mona is very frugal. You'll catch her stomach growling eventually.
Lastly, she loves positive attention and praise. She is a genius, after all!
