Harbinger of Doom
This adaptation of the Scales of War adventure path is set in the Forgotten Realms setting, a setting of high magic, high fantasy adventure with a rich, detailed history. There is much more information on the setting contained at the Forgotten Realms Wikia, but as much of that information stems from pre-Spellplague times, please note that it may have changed since.
The material plane of the setting is known as Toril, although it is in fact one of two twin planes, the other known as Abeir. The continent that this campaign is set on is known as Faerûn. There are also two co-existing planes alongside Toril that mirror its overarching landscape. The first is the Shadowfell, a realm of deep shadow and necrotic energy which the dead must cross before the afterlife, and the other is the Feywild, a twilight realm that shimmers with natural beauty and magic.
The silvery void of the Astral Sea is the home of the Deities, as well as native races such as the Githyanki. It is a place where the mind and spirit can alter reality through sheer force of will, and the deities utilise this to create their grand dominions.
At the other end of the spectrum is the Elemental Chaos, a realm of physical reality in its purest forms. All of the elements can be found here, combining, surging and sparring, endlessly regenerating. Great primordial beings reside here, lording over elemental realms shaped from the raw materials of creation.
The most widespread calendar in Faerûn is the Calendar of Harptos. It divides the year into twelve months of thirty days each. Additionally each month can be divided into three 10-day periods known as rides. There are also five holidays that occur between the months evenly distributed throughout the year, with a sixth holiday known as Shieldmeet occurring every four years. The names of the months and holidays follow, with a colloquial name for each month in parentheses.

The years are most commonly counted from the Dalereckoning (DR), which is taken from the Year of Sunrise (1 DR), when the Standing Stone was raised by the elves of Cormanthyr and the human Dalesfolk to signify their alliance. The years are also known by a name taken from the Roll of Years, which is said to signify a prophesy for the major events of that year. The starting year of the campaign is 1480 DR, the Year of Deep Water Drifting.
It is commonly known that the Spellplague began in the Year of Blue Fire (1385 DR), but it is not commonly known what caused it. Visibly, Spellplague appears as tongues of blue magical fire that disrupt arcane power and destabilise its effects… and while uncommon, pockets of it still exist in areas known as Plaguelands. The main effects of the plague lasted only ten years, but it left a legacy that remains nearly 100 years later: altered landscapes, political upheaval, the deaths of thousands, a drastically different cosmology and transfigured creatures.
In truth, the Spellplague was somehow triggered when the old goddess of magic, Mystra, was murdered at the hands of the evil deities Cyric and Shar. At her death, the Weave that she carefully tended unravelled, setting arcane magic loose upon the cosmos. Even a few deities were killed in the cosmic devastation that followed, and the divine dominions were uprooted and sent to drift in the Astral Sea. It also caused planar shifts that saw sections of Abeir and Toril exchange places, and other planes collapse into each other as their boundaries weakened.
