Beatrice is the hidden true antagonist of the 2021 Metroidvania-style game "Lost Ruins" by developer Altari games.
At the beginning of the game, Beatrice approaches the heroine - a girl who has suddenly appeared inside of a castle and has no memory of anything prior. Beatrice introduces herself as the castle's guardian and asks the heroine to help defeat "the followers of the evil Dark Lady". Not knowing what else to do, the heroine does as requested. However, after the last "follower" is defeated, Beatrice appears and reveals that the individuals were not minions of the Dark Lady, but girls whose souls were stolen and brought to this world. She adds that the "Dark Lady" isn't evil at all, and is in fact a goddess whose power she wishes to steal for herself. Beatrice forces the heroine to battle the goddess and afterwards (depending on the ending achieved) Beatrice either escapes with her newly acquired power or is killed by the heroine's holy sword.
