The Lord Regent is typically found in his private chambers or a secure command center within the tower. To lethally eliminate him, a direct confrontation or a stealthy assassination will work. For the non-lethal option, you must find his propaganda broadcast and replace it with a recording of his confessions. This requires finding the recording, accessing the broadcast station, and then activating it. This often involves navigating through several layers of security and solving a small puzzle. Be prepared for a final stand.
