[The marks on your body aren't random, Papa,] Ash's voice drifted through Raiden's consciousness as she demonstrated how to bend darkness into weaponized forms.
Raiden glanced at her with a puzzled expression as this felt more complex than the usual rituals he knew. He stood in the darkness on the green grass, adjusting his stance as he visualized an odachi sword.
"The lines are there to fill your entire body with darkness, Papa." Ash transformed as she spoke. Dark lines spread across his hands, neck and forehead, while her white hair became smoking white and fluffy.
"This is the first moon dragon form," she shrugged her shoulders as her pale skin began to glow more like the moon while she gestured her hand and a cup entirely made of darkness appeared.
"The darkness becomes yours once you're in it, and with enough mana you can shape it into whatever you want."
Raiden glanced at her, his cloudy white hair drifting in the darkness, wondering how she made it appear so effortless.
