Intro. The "Lion" King, whose real name is Artoria Pendragon, is the main antagonist in Fate/Grand Order's Camelot Singularity and an alternate and tragic version of King Arthur. Her detailed story is as follows: The Queen of Lions Plan When the Magi King Solomon began his plan to incinerate humanity, the "Goddess Rhongomyniad" (the Queen of Lions) perceived the situation from a divine perspective. He decided that humanity was doomed, and instead of saving them from destruction, he initiated his own method of "saving them" by absorbing virtuous souls into his Holy Spear to bring them to Avalon, preserving them from the imminent annihilation of the world. To execute his plan, he traveled to the Holy Land (the location of the Camelot Singularity) and established the Holy City of Camelot.
