Order of Whispers
The Order of Whispers is a secret society which developed from Turai Ossa's elite spy network. It was the Order of Whispers who sealed away Palawa Joko after the Battle of Jahai. They have also sealed away a Titan by the name Saevio Proelium. Ever since those days they are custodians, hunters of the corrupted and supernatural evil, so naturally when asked for help they are more than willing to assist in the defeat of Abaddon.
The order is currently based in the Chantry of Secrets.
