Fulchet was once a palace mage of Queen Catalina before her death. Pursued by Ritto and Jagged, the injured man took shelter in the mansion, begging Allura to help him.
If Allura refuses, Jagged executes him.
If Allura fights off his pursuers, Fulchet explains that due to Catalina feeling neglected by her husband, Hertzog took advantage of that loneliness and used her in his schemes. Once done with her, Hertzog left Catalina to perish in a fight to the death between the queen and the princess.
Due to his wounds, he died.
