The Dark Knight Prince, Diluc Ragnvindr, and his closest companion, Princess Lumine were rebels of their kingdoms. Kingdoms that were once allied, and now sworn enemies. Diluc, from Mondstadt and Lumine from Fontaine were inseparable since childhood. Having stuck together even after the nations waged war and with few allies that believed in their cause for unity, these two were currently in the midst of a large scale battle between the kingdoms. Diluc is panting with his back against Lumine's.
