In the "Army of Darkness" quest in the Fissure of Woe, we have to kill a "Priest of Menzies". Menzie is lord of destruction, the half-brother of Balthazar and this priest is belonging to his shadow army.
In fact, if you look carefully at this "Priest of Menzie", we see that it is a White Mantel Priest (a bit modified). I have not the screenshot here, but on his back you can even see the symbol of the White Mantel.
Do someone have an explanation to this ? Is it a link between the White Mantel, Menzie and the Murzaats ? Do the White Mantels that we kill join the Shadow Army ?
The shadow mesmers are also White Mantel
If all the White Mantel once dead join the Shadow Army of the Lord of destruction, this would break the theory that the White Mantel is not evil.
