Margarita was born as the daughter of Baron Dresden. She grew up in a family specialised in the cultivation of roses, which are even supplied to the House of Arnor.
After enrolling at Thors Military Academy in S.1204 to look for a future husband and become a better wife, her eye fell on Vincent Florald and offered him a grand rose, grown by her family, which symbolises passionate romance. Vincent clearly indicated that her love was not reciprocated, but she refused to give up.
Her efforts paid off after graduation. As of Trails of Cold Steel IV, she and Vincent are officially dating. Professionally, Margarita decided to help out her family.
