The prolonged siege is the greatest blow to morale and cohesion, and this is true for everyone—even the church clerics whose faith and stance were originally firm are not exempt.
When the situation is stable and there are no significant conflicts of interest, the church can maintain a semblance of balance and unity among its factions. Despite the factions' presence both inside and outside the cathedral, and the entangled interests and conflicts among various clerics and priests, at least everyone tries to uphold a superficial unity for the sake of their fellow church members—simply put, they give face to the Holy Light, and conflicts are kept from the public eye to safeguard the overall interests of the church.
However, when the church no longer brings any benefits and even becomes the source of threats, this superficial unity will start to fracture from within.
