Bitter Envy

From: Isabelle
Description: So, the Mistress and the Bird Catcher tried to bring Lady Peacock and her lover back to the City of Shadows. But they couldn’t do it... You know, I sense the presence of a stronger item here, a cursed item. Please lend me some artifacts, and I’ll try to identify it.
Completed: So that’s what was disturbing my aura! The Black Feather! I read about this technique. It’s a two-person spell that magic duos use to make another pair break up. One feather remains with the person placing the curse, and the other is planted on their victim.
