The world has suffered a tremendous geopolitical shift and even climate shift due to the sudden upsurge of magic. Humanity has suffered severe depopulation to an unprecedent scale due to the massive cataclismic clashes between the countries of old and the new powers of Witches and Supernals. Ironically, this seemed to allow nature to heal from the scars of the self-destructing consumism spiral of the late 20th and early 21st centuries... but barely any safe place is left, and people can die from plagues, disease or even predation by supernals at night. Practically no country has survived, except Australia and New Zealand. The combination of natural resources, sparse population and relatively developed lifestyle allowed them to agglutinate the last remnants of the old World's order in Strongholds, walled cities that are under the control of the United Nations (or what's left of it). These strongholds is where the GRAM draws its resources, funding and recruits.

Apparently, some Witches have managed to get something resemble societies working too, but they're hapzard, pale imitations of what used to be at best. (With the exception of Johannesburg, but that's a exception to the rule) Tales of hunters talk about dens of vice and abased debauchery, where life can be snuffed at the candle of the mighty and powerful, and sometimes inhumane, witches.

Despite how dire the situation is, strongholds still have access to the main commodities of modern life, and there's little if any shortage of anything. However it comes with a terrible price. Big brother is always watching, and regulations and rules are everywhere. The greater good is used as umbrella term to trample over even the most basic personal freedoms. Because witch genes are among the populace, there is no small sheer amount of paranoia and distrust among people. So, while the society is modern, it is also oppressive and stale, and makes many people join the high-risk high-gain ranks of GRAM, the only ones who venture outside the Strongholds to fight witches.

Sometimes, people aren't even given an option. Any confirmed witch match in the strongholds is forcefully recruited in their magic ranks, and kept under tight controls with electronic shackles. Supernals, who are even rarer, are vivisected usually... Even the mere thought of one joining the GRAM ranks is rare.

The Global Response Anti Magic forces are pretty much the only force capable of trading blows with witches and not suffer the fate of the sundered armies before them. With cutting edge technology boosted by their own magic forces, these daredevils thread into the chaotic anarchic world of today to restore what once was. They have a looser structure than most forces, and at times they're little more than adventurers or guerrilla. Casualties are high, as expected, but successful GRAM veterans enjoy many boons that normal citizens cannot.

There are two branches in GRAM. The magic users, sometimes called the Sorceresses and Sorcerers (to distinguish themselves from the Witches and Warlocks) are often kept separated and trained by their own, and then lent to the normal branches, the Troopers, to offer their magical expertise as backup. There is no small amount of friction because of this formula, but this was the most sensible solution to avoid infighting that was discovered.

In this chaotic world, there are countless threats and war-drunk witches to count and classify. The usual formula is that a cluster of witches rules over a certain are like a city-state of old, and keeps acolytes and supernals under their thumb. Some witches are even nomads, which raid the corpses of the cities of Old and unguarded settlements for a living. It is worth noting, however, that there are four witches who have rose to prominence and notoriety due to their sheer power and followers.

• The Witch of the North: Also known as the Winter Sorceress. Her stronghold is Iceland. She has relatively few people and followers, but has many dangerous supernals and beasts under her control. She is infamously for her ability to warp the weather and the climate to such an extent that men are frozen where they stand, as well as the only witch in the world capable of commanding an entire flock of dragons.
• The Witch of the West: Also known as the Bloody Dawn. Her stronghold is Mexico. A sadistic woman who has a disturbing penchant for human sacrifice and blood magic. West is the most warmongering of all the great four, and the people she comands are feral reavers and pirates who abduct people for the mesoamerican gods of old, clad in feathers and pelt. She has a great cult and is worshipped as High priestess.
• The Witch of the East: Also known as the Dead Queen. Her stronghold is Beijing. A powerful necromancer and spirit summoner, East is an eerie slippery opponent that rules a city where few denizens have a pulse, and can summon demons and spirits from unspeakable places. Dead Queen and Bloody Dawn have a long standing rivalry as they both compete for human sacrifices.
• The Witch of the South: Also known as the Lady of the Flames. Her stronghold is Johannesburg. South is the only witch who has managed to retain a level of followers and management that match the strongholds of the the Old World order. Johannesburg can boast a large population and even trade, but it is a rotten city, a den of vice where all the worst cravings of men and women are sated, all overseen by the eyes of South and her retainers. South is also the most industrious witch, and is locked in an arms race with the Old World order. She also has a feud with North for unknown reasons.
• The Fifth Witch: Also known as Morgan le Fay. An enigmatic Welsh woman who is currently the head of the GRAM sorceresses. For some reason she decided to side with the Old World order rather than start her own city country. While not widely acknowledged, many people think that Morgan was a keystone that allowed the survival of the Old World order in Australia and New Zealand and the creation of GRAM. To this day, Morgan is the only person who can strike any kind of fear in the other great Four witches (other than themselves).
