Solaria finally got her first reference.
As you can see, Solaria is a powerful sorcerer and a powerful magic knight. Although in this picture, she is wearing neither her robe nor her armor.

I have intentionally left out some information, such as her “尊名”(Respected name? Honored name? or some other what. Anyway, it's the name people use when they pray to her for help), because it involves more context than can be represented in this image.

(Since I cannot guarantee the accuracy of my translation, I send the Chinese version for comparison)
