Sisters of Silence - Vigils and Cadres: During the Era Indomitus, the Vigil Indomitus established satellite vigils throughout the Segmentum Solar, hoping they would prosper enough to be able to join later fleets of the Indomitus Crusade. Some of these vigils would not be ready by the time their appointed battle group passed by, beset by calamity or forced by circumstance into striking out on their own. Some would wait in the dark for many years, never to be reached as crusade forces were diverted and delayed, for despite Roboute Guilliman's superhuman logistical acumen, such tragedies of bureaucracy continued to haunt the Imperium in the Era Indomitus.Yet many more vigils joined their appointed battle groups and proved invaluable as their ships spread ever deeper into the beset Imperium. The presence of the Sisters of Silence helped to calm the turbulent Warp storms around the battle groups, allowing them to make far greater progress than their commanding groupmasters had hoped.Contact was made with lost conclaves of Silent Sisters, those who had unstintingly continued in their duty for generations. Where they were found, strongholds known as "vigils" were established with responsibility to undertake the Sisterhood's duty in a particular area, no longer alone but once again operating with the full authority of the Golden Throne. Some were small, with jurisdiction over a handful of star systems. Others could call upon many hundreds of Untouchable warriors and have since grown even further, their spheres of responsibility extending to entire sectors. Now, such strongholds of the Sisterhood as the Vigil of Darius III, the Segritaes Nebula Vigil, and the Vigil of Orshan's Belt are known far beyond their borders.Every vigil is granted high levels of autonomy. The number of its warriors varies depending on the area they must cover and the populations of the worlds therein, and some of the largest vigils number in the thousands, though a vigil most commonly numbers approximately 1,000 Silent Sisters. Most vigils are based within their spire-convent, usually a fortified keep at the heart of their territory, though those that accompany the Indomitus Crusade fleets nominate one of their capital ships as their mobile spire-convent.Most vow-sworn hunters spend little time within their spire-convents, their warriors constantly on the move, transiting between Black Ships, following the spoor of sorcery from system to system, and chasing down fleeing witches.Each vigil retains the colours that its founding sisters developed through millennia of isolation, from the deep blue and bright silver of the Vigil of Hrav-Ulan to the bone white and blood red of the Outer Solar Vigil. Every vigil divides its warriors into "cadres," and each cadre is given a unique designation before taking up the vigil's historic hues that were readily identifiable by their corresponding animal totem (the Frost Lynx, Ice Leopard, Iron Lynx, Raptor, White Falcons, etc.) and squad types which were differentiated by their armour colour schemes and unique iconography.The cadres are company-equivalent bodies, though it is rare for them to ever fight as one. As vigils are bound to uphold the Sisterhood's duties across a particular stretch of the Imperium, its cadres each carry out a particular facet of those duties. Some cadres investigate non-compliance with the Great Tithe, some are tasked with hunting down those Human psykers who have fled Imperial justice.In particularly high-risk areas, a Silent Sisterhood vigil will dedicate several cadres to the same duty. The Triventine Vigil, for example -- charged with the psychic purity of the Triventine trade routes northwest of Nocturne -- assign five whole cadres to the garrisoning of the region's Black Ships, which have allowed them to maintain the high frequency of their tithe harvests.In the execution of their specific duty, a cadre has access to every resource, asset, and piece of arcane equipment at the disposal of their vigil. As contact is re-established with star systems and sectors throughout the shattered Imperium in the wake of the Great Rift's birth, and the declaration of the Dispensatus Anathema is made known, more vigils are founded wherever the Sisters of Silence are rediscovered.
