“We are indeed familiar with the Nightborne's magic, but we were never allowed access to the Heart. It was a right reserved only for the Queen's favored.
However, we can still learn how to properly tap its magic.
Thousands of years ago, a Nightborne scholar studied the Heart and documented his findings in great detail. He was executed and the scroll of his writings banned, but the Nightfallen secreted it away in their escape.
If you obtain the scroll, we can help you.”
