A letter would be penned for all to see. Sealed with the official seal of The Office of the Divine Regent of the White Order, and pinned to the city's noticeboards.

An Official Response
From The
Divine Regent of the White Order
To all petty Sewer Gangs, and lowlife heretics of the underbelly of our fair Capital. The White Order does not exist as a medium for you to display your childish drawings. The White Order does not exist for you to make idle threats. The White Order does not exist to yield, or bend the knee to any mortal man, woman, nelfin, or Sewer dwelling child. The White Order will not, negotiate with its lessers.
Samon Eynsford is but one loyal servant, in the service to his Imperial Holiness, though he shall not be left behind.
This shall be your last, and only chance to surrender, Confessor Eynsford, or forever face damnation, and torture for all your mortal lives. You have no information. You have no leverage. You have no chance.
To any other would be criminals, I present a warning: stay in the sewers for which you belong, stay in the filth, and the dung. If you do so much as crawl from the dark place for which you hide, you will discover a pain only comparable to an eternity in exile from the blessed Spirit. And remember this: there can be no greater pain, than damnation.
You rob not a bank, or a shop, or a place of gold. You rob a pious institution. One wonders what goes through your minds? Surely nothing, for the idiocracy for which your gang leads itself by seeps through your every word. It is on this, that I announce this to be our last communication. May the Spirit show mercy.
Médard Ravenstad,
High Reverend of Regalia,
& Divine Regent of the White Order.
