Though Verloren has been sealed away in Pandora's Box for over 1000 years, his messengers, the Kor, find and contact humans to bring them under his influence. If a contract is made, a mark appears on the person's chest. This is known as "Verloren's curse," and it indicates one's heart being eaten by darkness. One of the duties of the "07-Ghosts" is to fight against Verloren and his curse and try to stop contracts from being fulfilled. Only the Bishops can remove Verloren's curse.
