Time for a quick history lesson: visualise with me. The year is sometime in the late 14th century, place: Korea. Or, as it's known at the time, Goryeo. Korea's been under the occupation of the disintegrating Mongol Empire for some years, and at war for much longer. The ruling dynasty of Goryeo is losing its credibility - the royal family keep intermarrying with the Mongol Yuan dynasty imperial family, and are genuinely poor rulers. If you were a citizen of Goryeo at this time wouldn't you agree it's time for a change?
Well, that's exactly what happened. General Yi Seong-Gye had gained power and respect during the late 1370s and early 1380s by generally just being a great military mind, and in the wake of the rise of the Ming Dynasty in what is now China the court of Goryeo splits into two factions, one of which was led by General Yi and one led by a rival general. To put things simply, General Yi supported the Ming Dynasty but was chosen to lead an attack against them - he said no thanks and turned on his King, carrying out a coup d'etat that ended in the deaths of the king and his son and with Yi in control of the throne, at first through a puppet king and then with his own coronation. And that, in 1392, marked the end of Goryeo and the rise of Joseon, ruled by the newly-christened Taejo. Highest ancestor.
Now fast forward a few centuries, to the late 1800s, when Emperor Gojong of Korea rules. Yi Deok-Mi is born, a daughter of Gojong and princess of Korea. With controversy surrounding her birth (rumours that she was born to a Japanese woman seemed a popular theory), Deok-Mi was hidden away from all eyes; muggle and magic alike. Although she was still styled as Princess Deok-Mi for a large portion of her childhood, as soon as she reached the age to attend Mahoutokoro, her name was promptly changed to Taejo Deok-Mi after her distant ancestor in order to avoid all connections between her and the imperial family. After choosing to live in seclusion in Seoul, Deok-Mi now serves as the link between the current Taejo Family and the royal house of Yi - enabling her descendants to have claims to royal titles.
Fast forward again to Deok-Mi's six-times great granddaughter, Taejo Ha-Neul. One of the main pretenders to the magical Korean throne, Ha-Neul grew up in Seoul in the same palace that her six-times great grandmother had lived in in seclusion, and eventually attended Mahoutokoro. It is here that she met the muggle-born wizard Hwang Yoon-Chul, who wooed her. Though against Ha-Neul's wishes, he was more than happy to take on the surname of Taejo - the two reached a compromise with having their children take on her surname instead of his, rather than he himself. Ha-Neul is too fond of tradition.
The couple had three children in quick succession: Mi-Ah, Mi-Kyung and Hae-Won, before Ha-Neul's career took a different direction. She joined the ministry, and embarked on a political journey with the end goal being President of Magic. Of course, she took some time out to give birth to her next two children: Iseul, and finally, Mi-Yeon. Around a year later, Yoon-Chul took the children to Britain so that they could attend Hogwarts, and a year later Ha-Neul was elected as President of Magic of South Korea.
Mi-Kyung was given the name Cordelia when the family moved to Britain, her mother's love for Shakespeare being a key factor. She wanted her second daughter to be resilient and do everything for the right reasons. Perhaps it was something too pushed upon her for those two elements would make up the better part of Cordelia's personality. Cordelia adapted to life in England fairly quickly, picking up the language with an ease and definitely responding to the culture there better than that of the Korean equivalent. She enjoyed the freedom that was given to her and, just like her mother had done, she set her aspirations high in regards to her future. Though the option of Kwikspell Tutoring was one her father had hoped Cordelia would choose - as to immerse herself in her magical roots from a young age - she ultimately ended up choosing to attend a muggle primary school. Being so young, whilst she had feelings that her family were different, she never could pinpoint what it was and thus decided to do the norm in Britain.
Cordelia's childhood was, as expected, good and uneventful. The most excited she got was when she was seven and cracked a door in two when angry once. Originally thinking she was some sort of monster, she was calmed with reassurance from her father that it was normal for them. From then on, though she still attended her muggle primary school, the involvement of her father teaching her the basics of magic became a larger part of her life. Though she dabbled in a few Kwikspell lessons here and there, Cordelia's primary learning influence was her muggle school as she refused to have herself disrupted. Olympia leaving for Hogwarts, naturally, caused her to become more interested in magic, but it was by no means an easy thing to let go of the muggle-ish life she had led thus far.
Cordelia's now in her seventh year at Hogwarts, having received her acceptance letter at the age of eleven and being sorted into _____ house. Having been the eldest Taejo at Hogwarts for the past few years and, in this upcoming year, having all three of her younger siblings with her, she feels an unprecedented amount of pressure to lead them in good form so that the Taejo name isn't tarnished. After all, her mother's just joined the family after her second term as the President of Magic of South Korea.
