"What?!" Talon blurted out unconsciously when he heard the number. It immediately struck his mind where he least expected it. "A few million kilometers in depth? That's ridiculous."
"It is pretty deep. Usually, Aetherial Lakes go deep enough to reach the core of the planet. In this planet's case, it's a few million kilometers down to the core, so it goes that deep. The amount of water in such a seamless lake is unfathomable." She replied with an impressed look on her face.
Even though Acrypha was knowledgeable about this phenomenon, she still finds it fascinating to talk about. These lakes are the perfect example of 'Don't judge a book by its cover'. They looked small, almost like puddles of water. But, their depth and history were simply unfathomable.
