The phrase "wake the dead" has often been used to describe the general flavor of Decadre. After two solid months of depression and near catatonia, Sigil is jolted back to life by the Doomguard and their sponsorship of this month. This is because the Sinkers see it as their sacred duty to embody the storms which a "normal" winter usually delivers. They feel they are justified in their behavior because - if one follows the philosophical model begun in the Autumn - after the body dies, it rots.
Factol's Day of Decadre, in addition to being one of the most widely noticed holidays in Sigil, rivals those of the months of Sacrilegion and Capricious for being the most varied. While the general theme is the same, the specific implementation varies from factol to factol, if not from year to year. The Doomguard celebrate the start of their month by holding a large and public demonstration of Entropy. This most common version has been the complete destruction of a building or large object which the faction has purchased (or made) just for the occasion. This Ritual of Rot starts with First Light and ends at Last Light. Over the course of the day, representatives of the faction proceed to use a wide variety of means to destroy the target as completely, but as creatively, as possible. Thus, buildings are taken down brick-by-brick and nail-by-nail, while statues are subject to the effects of summoned winds and conjured waters to simulate natural erosion. Occasionally, the Ritual has taken the form of public challenge - that is, anyone can bring an object to the Doomguard to see if they can apply Entropy to it. Recently, under the leadership of Factol Pentar, the Ritual has taken on a darker and more dangerous tone. Under her guidance, the targets of the Factol's Day celebration are not owned by the faction or handed over willingly.
The efforts of the faction for the rest of Decadre, while visible, tend to resemble the Entropy they revere - a large, chaotic mass that ends up gaining or losing nothing. While the members of the Doomguard follow the examples of the other factions and make their presence and philosophy felt throughout the City of Doors, it is not a unified or well-coordinated effort. This comes from the fact that the Sinkers are a far more fractious lot in their personal views of how to accomplish their goals than other factioneers. The three camps within the faction seem to become even more like separate groups during Decadre than at any other time of the year. Those who seek a more active and faster approach to the decay of the multiverse spend their days causing trouble throughout Sigil by breaking things and sabotaging buildings or projects. The neutral members of the Sinkers, who prefer to let things die at their own pace without interference, tend to act as militant caretakers - they will "adopt" a location or an object and see to it that no one attempts to either heal or harm it, beyond what time alone does. Naturally, these factioneers run a great risk of running afoul of the dabus if they attempt to prevent the trimming of razorvine. And finally, there is the small minority of the Doomguard who feel that they have to slow down the general rate of decay. These members present an odd picture as they move about Sigil, repairing and fixing things - usually ones which have recently fallen prey to their more active brethren.
Decadre's style of influence on the rest of Sigil is similar to that seen in the months of Savorus or Catechism; day-to-day living and the physical structure of the city is affected much more than the people themselves. While the residents of the Cage have finally shaken off the lethargy and mental fog of the late Philosophical Autumn and early Winter, it seems that multiverse has turned against them. Things do not go smoothly during Decadre as practically anything that can go wrong, does. The wagon wheels on an important cargo shipment will break. The roof will spring a leak right over a bookcase and ruin several tomes. The previous customer of a merchant will have just bought the last item in stock that you needed. Everything seems to go out of its way to prove that the Doomguard are at least partially right - things do break down. While all of this is very frustrating, this pervasive decay does also work for the good. Surprisingly, the overall crime rate in Sigil is way down during Decadre. This is mainly due to the fact that the criminal's plans never seem to work out exactly right: the Harmonium patrol is early in its rounds, the lookout falls asleep, or no vulnerable victim is available. Even the dabus aren't immune from the month's influence; they seem more harried and rude as the number of potholes to patch, buildings to fix, and razorvine patches to trim rise to their highest levels of the year.
The so-called Philosophical Wind makes a strong resurgence in the month of Decadre. However, in this case, it's not the sounds of reasoned debate but emotional shouting matches that fill the streets. As the Doomguard are fond of pointing out, even intangibles like personal interaction aren't immune to the embrace of Entropy. The general air of bad luck frays people's nerves and shortens their tempers. Any one of numerous small decay problems could be the proverbial straw which causes a sod to lose his control and start an argument. Some factioneers (not exclusively members of the Doomguard) like to preach from street corners, using the frustrations of the day to illustrate some point before they are shouted down by the passing crowds. All of these verbal outbursts don't last long, however. They are either quickly ended by mutual disgust, or else they degenerate into a brawl. As if this wasn't enough activity, there are also religious festivals sponsored by the various powers of Corruption, Decay, and Destruction held during this month.
