天才俱樂部#4，號稱「寂靜領主」。波爾卡•卡卡目的資料同其形象一樣神秘——她曾在全宇宙範圍內銷毀了自己的畫像和雕塑，並被懷疑與眾多俱樂部會員的死亡有關，包括#27帝皇魯珀特。
黑塔對「寂靜領主」很感興趣：波爾卡•卡卡目雖已經很多年沒有消息，黑塔卻認定她仍然活著。她的身影捉摸不定，於銀河中留下的信息僅有寥寥，有關她的傳言則不在少數：似乎投了唯一一張以利亞薩拉斯的反對票，很可能與「虛無」的第Ⅸ機關有關。
若一位女士脫下白褂後換上張揚的糖果色晚禮服，手握匕首現身銀河中，請目擊者一定要大聲呼救：「寂靜領主」很可能找上任何人。
Genius Society #4, known as the Lord of Silence, information on Polka Kakamond is as mysterious as her appearance. She has had her portraits and sculptures destroyed across the universe, and is suspected of being involved in the deaths of many Society members, including Genius Society #27, Emperor Rubert.
Herta is very interested in the Lord of Silence. Although there has been no news from Polka Kakamond for many years, Herta believes that she is still alive. She is elusive, and there is scarce information of her left in the universe. On the other hand, there are many rumors about her: Apparently she was the only one to vote against Elias Salas and probably having something to do with Nihility's Device IX.
If a woman removes her white coat and puts on a flashy candy-colored evening dress and appears in the cosmos with a dagger in hand, witnesses must call for help: The Lord of Silence is likely to target anyone.
