Some may not know that the Silens Vindex is just a glorified and updated version of the Abyssus Dolus. This was brought about by the famous betrayal of Nabeshin. Leaving BuMp on his own to manage the guild, Nabeshin flocked to requiem, and then even Freya herself. His guild nearly collapsed and a major change was needed for it to sustain itself and grow stronger. This major change was the name. To take down Requiem.
