The Magisters discovered its many effects as they reverse engineered this weapon, which originally belonged to the Vulgus Order of Truth. The weapon called Divine Punishment was of special note. It displays the Order of Truth's special power by using Arche and materializing it in a similar form.
They originally sought to demonstrate the power of this Order of Truth firearm through the use of Arche. The Order of Truth has been known to trigger a special phenomenon like Arche, a phenomenon that cannot be explained simply with a firearm's performance ability.
