Kian Crag
The eighth child of Marquis Crag.
Kian possessed far more talent than any of his siblings and had been praised due to it from a young age.
He was born into a family that possessed superior magic talent even among other marquis houses, and naturally, was very proud about being the most talented in such a family.
That was until his father's second wife gave birth to his younger sister.
The ninth child of Marquis Crag, a girl who possessed even more talent for magic, ether, Aether and many other energies than the marquis himself.
All the vassals who were at his beck and call abandoned him to curry favour with his younger sister, no one praised him anymore, and even his own mother favoured his younger half-sister than him.
This led him to develop hatred towards his younger sister and eventually, an inferiority complex.
