Victor and Diana Vance. The name Victor means "conquerer" while the name Diana means "divine".
They were the most influential couple Planet Earth had ever known. Their relationship was scandal-free and the love they shared was pure. Even after the destruction of Earth, they live on in Varya's memories forever. They're the reason she can continue moving forward just as much as her children and the man she married.
When Varya looked down at the twins as they lay in the hospital crib together, she realized immediately she wanted to name them after her parents to keep their memory alive in a new way. Each time the names of her children were uttered, the memory of her parents would live on forever.
The imperial couple left the hospital after a couple of days and Basileus Jr. was finally able to meet his siblings.
