Arthur and Elara, the protagonist and his twin sister. Despite being twins, there was almost no shared talent between them.
Arthur was the most talented son in the royal family in the combat aspect. He had absolute talent in all types of swords and in mana control. His only affinity was solar, which held the power of absolute destruction, self healing, and slightly good in healing others.
And with all that, he had a trait that made his talent and affinity even stronger. Unfortunately, he didn't have a soul-bound artifact.
Elara, on the other hand, was born blind and physically weak. She had a perfect talent for rune-inscribing and forging, but only peak mana control and didn't have a talent for any weapon at all.
Her affinity was Holy, which unlike light, solar, and divine, didn't have any known attacking spells. All she could do was make some barriers and give buffs for her allies. She wasn't useless, but was too weak.
