Raphael was born and raised in Manchester, England. He is from a wealthy pureblood family that is well-known in the Wizarding world - the Morgenthau family. Despite this status, the Morgenthaus are known for their association with and wealthy disposition towards Muggle-borns, and by extension, Muggles themselves, and would often rally and lobby for their rights in the Ministry of Magic. Growing up in this environment, Raphael became compassionate and light-hearted, with a flair for activism, and a knack for correctly identifying what was right from wrong. At a young age, he had already established a sense of righteousness, and this had greatly affected his attitude and personality as he slowly grew up.
At age 11, like most of his family, he was admitted to Hogwarts School of Witchcraft and Wizardry and was sorted into Gryffindor House. His life at school was very fruitful, and there, he met lifelong friends. He played Quidditch and was also made Prefect in his later years as a student. It was also there where he discovered his passion for duelling, and his love for his Defense Against the Dark Arts class - often devoting time into his "hobby" so that he could become better and better at wizarding combat. Because of this, he decided to work at the Ministry of Magic after graduation, and with his sense of righteousness coming into play, had applied to become an Auror.
During his tenure as an Auror, he was sent to the Middle East to deal with some illegal magical activity. During one of his run-ins with the people involved, he was greatly injured and was recommended to go back the United Kingdom. Staying positive and knowing that he could still fight, he remained on the field, and after recovering, had helped his co-Aurors in shutting down the illegal activity - which turned out to be a black market for exotic magical creatures. After this mission, he had decided to retire from the field and do office work instead. He met a co-worker in the Ministry, Adella Simpson, and they fell in love. They started dating and eventually got married after about three years.
Because they were still quite young, their marriage started becoming rocky two years in. Still instilled with the ideas that he could help the world, Raphael found a new interest in teaching, and was in fact, hired by Durmstrang to be one of their professors. Adella was not a fan of the idea, mainly because of the long distance thing, but Raphael insisted. And so, he went to Northern Europe, away from his wife who remained in Britain, and started teaching Defense Against the Dark Arts - his favorite subject back when he was still a student.
After a couple of years teaching at Durmstrang, Raphael was recognized by Castelobruxo and offered him a job as well. As a person with a natural inkling for travelling and adventure, and because of the better pay, Raphael accepted the post of Charms professor, and transferred to South America. This strained his marriage more, and he slowly found himself caring less and less about his wife, and more and more about his career. Adella felt neglected, which caused her to cheat with one of Raphael's close friends from the British Auror Force. One night, when Raphael had decided to go home for a long weekend and surprise Adella, he found her in bed with another man. Furious, he ended their marriage right then and there and immediately filed for divorce.
He took a leave of absence from Castelobruxo so he could collect his thoughts, and entered probably the darkest moment in his life. He started sleeping around England, with men and women, he didn't care. He wanted retribution; revenge for what his wife did to him. Only when he had reached his lowest point did he realize that he was also to blame. All those years caring about transforming the lives of those he teaches was traded for what he had with his wife - the first woman he ever truly loved. And so, like what he did when he was injured long ago, he started looking at things more positively, and slowly rebuilt himself as a person and let bygones be bygones.
He came back to Castelobruxo to teach for one more year before resigning and returning to the United Kingdom to spend some time with his family and finalize his divorce. Currently, he is planning to make a sort of homecoming and apply for a teaching post at Hogwarts School of Witchcraft and Wizardry.
