The Silent Order is the discipline of the swift seraphim host — not a second wellspring of faith, but the way the gang governs how it spends the one faith it earns. Because its jump bodies strike and withdraw, taking few casualties, this gang generates the least Faith of any Order, and so it hoards what it earns and spends it only where it decides a battle: the redeploy, the ward, the held line.
The Order leans its Faith into three Acts and no others of flourish — Hand of the Emperor (the fighter stands from Pinned or makes a free 6" redeploy), The Emperor's Aegis (ward the one incoming attack that would have landed, or ignore a wound), and Light of the Emperor (the holding screen auto-passes its Nerve). A fighter that has already acted may add the free disengage of Strike and Fade. Nothing is spent simply to kill; every scarce miracle buys distance, denial, or the empty firing position. Trap the host where it must stand, and its slow-filling reliquary runs dry — but give it room, and it takes a position at a time and is never once caught to answer for it.
