Praise the Sun.
The signature catchphrase the citizens of Solara say whenever they honor "The Sun," whom they treat as their Deity.
One of the first Apostles of The Sun had founded the Solara Kingdom. Since its establishment, everyone who hailed from the kingdom had remained loyal to the God who watched over them.
Thanks to their fate, the people living in that domain were blessed with Sun Magic, especially the Royal Family, who could wield a fraction of their Founder King's power.
Simply put, only the chosen ones could become a Solar Knight, Solar Saint, and Solar Saintess, most commonly exclusive to those who possessed the bloodline of the Royal Family.
Celestria was a Solar Saintess who sometimes received visions from The Sun.
In fact, she learned from one of her visions that when she arrived at the academy, she would meet someone who would change her life forever.
She was certain that this person wasn't Alex.
