5th Age Campaigns' home rules
In 1482DR, Bhaal, the long-dead god of murder, was reborn in Baldur’s Gate amid chaos and bloodshed. The return of Bhaal and his apparent reclamation of the domain of murder from Cyric led some scholars to believe that the rules by which all deities must abide were in flux, and this event marked for them the beginning of the Second Sundering (see an History of the Realms for more details about the First Sundering).
Strange calamities began to occur throughout Faerun, and conflicts broke out in many regions of the continent. Events like earthquake, floods, drought re-shaped some of the lands, undoing the changes brought upon by the Spellplague but also ending its wider effects. Pockets of wild magic manifestations are still fairly common across Faerun, amid the turmoils and upheavals brought up by these calamities.
In the North, between 1484DR and 1485DR the orcs descended as a horde upon the land in great numbers, pillaging and massacring, while the region was under the effect of roiling clouds of smoke or some other foul substance that turned daylight into something less than moonlight and hid the stars entirely, called The Darkening . The Silver Marches were the most affected, with Sundabar being all but destroyed, and Silverymoon and the Dwarven Citadel being besieged by orcs and drows alike.
When the Orc horde chieftain Hartusk is killed in battle by a Dwarven lord, the horde’s multiple tribes splinter off, relieving the besieged cities and citadels. Despite the retreat of the Orcs, the fall of Sundabar precipitated the fall of the League of the Silver Marches, as the dwarves retreated to the Underdark and to their citadels, blaming their former allies, especially Silverymoon and Everlund, for not helping defend Sundabar.
In the Western part of the North, the Hosttower of the Arcane rose again in Luskan, along with the Arcane Brotherhood, while in Waterdeep and Neverwinter, efforts were made to clear these cities of century-old rubble and neglect, while ships claiming to come from Evermeet, Lantan and Nimbral sailed into ports of the Sword Coast.
In the Eastern parts of the North, the long-subjugated bedine people rebelled against the Netherese, as their masters waged a war against the southern kingdom of Cormyr, with the help of their puppet kingdom of Sembia. Netheril attacked Myth Drannor by flying the City of Shade above it. In a struggle for control of its mythal, the flying capital of Netheril was brought crashing down on Myth Drannor, resulting in the cataclysmic destruction of both. Forced to retreat, the last remnants of the Netherese forces waged battle with the bedines for the control of Memory Spire, and the battle awakened a hive of phaerimms, whose draining magic made Anauroch a desert again.
Across the North the last two winters lasted longer than any winter on records. The solstices and equinoxes have somehow drifted. Later seasons follow suit, with each starting and ending later than expected. Prayers to the gods for knowledge and mercy seem to go unacknowledged.
The campaign started at the beginning of the year 1489DR.
