Dainslef, the bough keeper, and the twilight sword. His title to the nation of Khaenri'ah's. He swore to protect his people, and Lumine too. But he can't help but feel like he failed, as he slowly watches Lumine turn into something else... She eventually became the Princess of the Abyss Order, leading the survivors (and their monstrous descendants) against Celestia and the Archons

One day he was sparing with someone in the abyss order. They're big and strong but no match to dain, after the match they stood face to face

The man laughed and stared him in the eye, with a grin and spoke in a menacing dark tone "tell me Dain, why are you so loyal to the abyss? Is it the abyss itself? Or are you here for someone?"

Dainslef rolled his eyes and crossed his arms "I'm here to protect the people of Khaenri'ah's. It's my sworn duty."
