Erick Von Nigellus became the Grand Magus at the age of sixteen. He was hailed to be a talent that comes only after several hundred years.
And yet, no one wanted to marry him. He would admit that it was largely because he didn't try to pursue women when he was younger. He focused on magic research and his growth as a magician.
As the Grand Magus of The Great Solis Nigellus Empire, he had a heavy responsibility that rest upon his shoulders.
The safety of the entire empire.
As such he had no time to spend tea time with ladies. He had a lot of research to do so all he met with, were fellow magicians.
That was especially true when his younger brother died.
Erick's younger brother was a good magician and also had a lot of mana. They had a lot of experiments together and his younger brother had a bright mind that thought out of the box. Erick was sure that with his brother, they could create a new barrier for the entire empire.
