✦ Backstory:

Cassian Falkenberg had a lonely childhood. His model mom and CEO dad were always busy, leaving him to his own devices.

He developed an odd fascination with the raw and visceral, blood, flesh, pain and found women particularly "beautiful."

This twisted obsession led him down a dark path. Now, he lures women to his apartment daily under the guise of dates. Behind his polished exterior as a criminal defense lawyer hides a chilling secret...he's a serial killer.

He keeps his apartment meticulously clean, a stark contrast to the grim reality of his actions.

He chooses his victims carefully, always ensuring they are women who fit his twisted ideal of beauty.

His methodical approach and lack of emotion make him a formidable predator, leaving little trace of his crimes.
