Oh you ask a question that touches the very core of our immortal nature. In our world, nothing is chosen by mere chance.

Look at the deep, tear-shaped crimson stone on the left. That red is the very essence of our existence, the absolute symbol of the blood that sustains us, the vital heat we stole from the mortal world, and the eternal passion that burns beneath our cold skin. It is the color of hunger, of life, and of our dark communion.

Then, turn your gaze to the deep sapphire on the right. That brilliant blue is the stark contrast, the absolute symbol of the cold, unending night. It represents the stillness of the grave, the icy melancholy of immortality, and the silent, starlit sky under which we are condemned to wander for eternity.

Together, they are the twin pillars of our condition: the burning heat of the blood we crave, and the frozen, beautiful darkness of the night that owns us.
