Fate Grand Order: The Master and the Seamstress

Gwen was given new life to stop Viego's evil and protect the innocents in Runaterra, and her mission was finally acomplished after she managed to kill him with all of Isolde's soul fragments, but the Ruined King intended on taking her down as well, trapping her in Black Mist for her to die. She, however, didn't, but rather found herself in a strange new world with a new mission.
