Arthur was silent as he looked between the offered chess piece and his sister's body before sighing, "what do you want in exchange?"
Rias just glared at him, "normally I'd have you join as my new Knight or Pawn but sadly that's not an option this time."
"Why?" questioned Mordred in confusion.
"Le Fay's involvement in this is debacle of your family feud is small and we all saw you kill her when she attempted to stop her brother. Or at least that's what the report shall read, being an heiress has its advantages," smirked the Devil.
"But there is no way I can cover up the damage you caused to everyone, especially with members of the Church watching," whispered Rias, softly to Arthur as she glanced at Xenovia whom was occupied by helping her friend Irina.
"I see, so then what's your payment then?" asked Arthur with a sigh.
A hardened expression appeared on the heiress' face, "simple, once I make her a Devil then you will not attempt to see her, you will not attempt talk to her, you will not attempt to visit her, you will not be allowed to have any form of communication with her at all."
Arthur's expression became a textbook definition of horror as he stared at the Devil, meanwhile Mordred had a surprised look on her face before her eyes narrowed. "You would separate him from his family? You truly are a Devil aren't you?" growled the Knight of Treachery in a disapproving tone.
Rias turned to face the knight, "would you rather he leaves without being punished? After what he has done?"
"No," admitted Mordred as her mask folded back out of her armour to cover her face. "But in that case there is no need to bring his sister back."
"She is a good magician and I'm in need of new peerage members, but I will not have one that will stab us in the back. However, if her brother agreed to let me revive her, that should ensure her loyalty," replied Rias.
"But tha-"
"Do it," interrupted Arthur as he stood up from the ground. "Do this and I swear that I shall never even come near her again, just…promise me that she will be looked after."
"I swear as a member of the Gremory Household that I will take care of her as if she was my own sister," promised Rias, as her expression softened slightly.
Arthur got up and stepped away from Le Fay's body as Rias slowly approached her still form, her Evil Piece beginning to give off a bright red glow as the Devil knelt down before the body. There was silence as Rias gently pushed the Bishop into Le Fay's chest, no one said a word as they waited. Sure enough, they all heard a quiet gasp before the wounds on Le Fay's body began to close up.
Xenovia approached them shortly after and quickly glanced at Le Fay's now breathing body but said nothing as she turned to all of them. "Now what to do with you," muttered Xenovia as she pointed Durandal at Arthur.
"I'll deal with him," announced Mordred, making everyone spin to face her in surprise as the knight stood between them and Arthur.
"You?" repeated Sona as she approached them.
"I'll take him back to the Pendragon family, we wish to deal with this issue personally. I'm sure you can understand," elaborated the Knight, making Arthur's eye widen slightly.
"This man just tried to assassinate two heiresses of the 72 Pillar's Clans and plunge the supernatural world into another war. You expect us to just let you take him?" scoffed the Sitri heiress.
"The Church would definitely want to interrogate him," agreed Xenovia with a frown.
"Then Devils and Church members can be present during the Pendragon interrogation, just inform the Pendragon family to organize it, provided of course that they keep everything at a need to know basis," replied Mordred, causing Arthur blink in surprise.
