"The dead outnumber the living one hundred thousand to one."
Around the same time, reports began coming from the eastern part of North America of a spate of mass murder, with people going from house to house, killing as they went. Later reports indicated that the killers were partially eating their victims. Finally, the truth came out after a series of government meetings -- the radiation from the Venus probe was animating the unburied dead. A series of rescue stations were set up, and the governments, which had previously encouraged people to stay in their homes, told the people to go to these rescue stations. The National Guard was mobilized in the affected states, and groups of hunters led by these and law enforcement officers began hunting down the ghouls.
The undead's numbers were rapidly growing, however, and soon several rescue stations were overrun. Changes happened so quickly that the media couldn't keep up, sending unwitting people into the undead's clutches and swelling their numbers. Finally, as government control began breaking down and the phenomenon was felt elsewhere, some of these hunting groups turned into roving looters, taking advantage of the situation, and any lone travelers they came across. Others took whatever vehicles they could and fled to whatever seemed safe from the undead; defensible buildings in the middle of nowhere, whatever islands they could get to, and so forth. Fuel became a rare commodity as people fled from the affected areas.
The only exceptions were the military bases that had survived the initial attacks. These bases often looked for survivors, and most were already hosting scientific teams that were looking into the problem soon after it began. As time went on, however, the very few survivors that were found dwindled to none, and several years after the dead began to rise, the living, holed into whatever secure bases they could find, were outnumbered by the undead nearly 100,000 to one.
The Giovanni clan struck a deal with a group of Spectres; the wraiths would begin skinriding some unburied corpses, and the confusion causes by this in both realms would give the Giovanni the chance to establish themselves in power. Giovanni sources in NASA gave them early warning of the radiation the probe carried back with it, and the decision soon came back from Venice: it was time. The killings started mass confusion in the real world, and that triggered a huge Maelstrom in the Shadowlands.
The Euthanatos were among the first to realize what was going on, and start efforts against it. They took advantage of the Venus probe to establish coincidence, and got announcements out. The Camarilla princes were able to figure out something supernatural was going on, and were already working municipal entities under their control against the threat. The Sabbat went to ground, waiting to see what happened.
The Technocracy used the incident to eliminate the Void Engineers. The New World Order and Syndicate decided that the Engineers had veered away from their purposes after the recent moon landinds, and with the aid of the relatively new Virtual Adepts, unwittingly eliminated all possibility of averting disaster as all means of turning the probe away were lost in the resulting infighting.
Soon, however, the Giovanni found the situation falling out of even their control, as the Spectres continued massing. The Euthanatos tried to mobilize the Traditions against the undead, eventually succeeding in getting the Dreamspeakers, Verbena and Celestial Chorus on their side. The others, especially the Sons of Ether and the Hermetics, wanted to study them, looking for a more comprehensive solution. Meanwhile, waves of ghouls began running into the Garou and other lycanthropes. They cut swaths through each other, but the dead could renew themselves faster than the werefolk, and the changers were decimated -- even the Black Spiral Dancers found they were safe only in their hives, and even then they had to deal with their own dead.
As central control broke down, the Sabbat and Anarchs came out of the woodwork, seizing control of many cities from the Camarilla, however short lived this control would be. At this point, the trods to the Dreaming all closed; the Changelings were on their own, and the Glamour of this world was decreasing rapidly.
By the time of the events of "Day of the Dead," most of the Kindred are in torpor due to lack of blood sources, although some have taken to drinking from animals, and the Camarilla, Sabbat, and Black Hand have all effectively ceased to exist. The Ravnos that remain have taken to travelling with Rom survivors full-time, protecting them from the undead and discreetly taking blood when they can. The Setites also maintain a herd of sorts. The remaining lycanthropes are scattered in small groups, but are outnumbered worse than the humans are. The Technocracy has mostly fallen; the only remaining Conventions of note are the Virtual Adepts, Iteration X, and the Progenitors, who are now working with the Order of Hermes on a solution. The Akashic Brotherhood eventually joined the Euthanatos and Verbena in fighting the undead, largely unsuccessfully. The only groups mostly intact out of all the supernaturals are the Nosferatu and the Sluagh; except for this group, the Changelings are largely extinct.
One thing I didn't think of was a Living Dead Garou. If you want to use these rules in a Werewolf campaign, I recommend using Garou Living Dead as NPCs. Strongly.
