Tyranny of Dragons (Nerd Immersion)
The Time of Troubles, also known as the Arrival, the Godswar and the Avatar Crisis, was a cataclysmic time period in the chronology of Faerûn. Taking place during 1358 DR, the Year of Shadows, the Time of Troubles was a period during which the deities of Faerûn were forced to walk the earth in their mortal avatar forms. Several major deities died during the Time of Troubles and a handful of mortals rose to divinity.
The Time of Troubles was precipitated by an attempt by the gods Bane and Myrkul to steal the Tablets of Fate from the overdeity Ao. Angry at the gods for their habitual pursuit of power and negligence toward their mortal faithful, Lord Ao relegated every god (except for the guardian god Helm, selected to protect the gates to the heavens) to walk among their followers on the earth. The immediate effects of this edict were threefold. First, divine magic (spells granted to clerics by their patron deities) ceased to function altogether unless the cleric was within one mile of their deity’s avatar. Second, arcane magic (a force channeled from the Weave by wizards and sorcerers) ceased to be regulated by its steward, Mystra and became dangerously unpredictable. Third, the characteristically immortal and aloof deities were now vulnerable (though still devastatingly powerful) and dwelling among the civilizations of Faerûn.
Era of Upheaval 1479 DR – Present (1489)
The Era of Upheaval was the name given, in 1479 DR, to the time from the Avatar Crisis through the time of the Spellplague, the merging of Abeir and Toril until present day.
When Ao the Overgod destroyed the Tablets of Fate at the conclusion of the Time of Troubles, he instigated the Era of Upheaval. The Tablets defined the laws of Realmspace and kept it relatively stable. Without them, chaos ensued and the worlds of Abeir and Toril, separated many thousands of years ago, slowly started to overlap. The Spellplague drastically sped up this process. The Sundering involves the re-separation of those worlds. In addition, Ao will rewrite the Tablets of Fate, and the gods, unsure of what this will do to them and their power, make efforts with their most powerful servants to prepare for that event.
The Sundering is somehow connected to The Sundering that took place around -17600 DR when an elven High Magic ritual went both forward and backward in time to create Evermeet.
The Spellplague was a disaster that struck the Realms on 29th Tarsakh, the Year of Blue Fire, 1385 DR. It was caused by Mystra’s assassination at the hands of Cyric and Shar. With the goddess’s death, the Weave, the universal structure of arcane forces, convulsed. It continued for a decade, leading to the Wailing Years, during which arcane magic ceased to function and the planet of Toril was transformed.
Augathra the Mad wrote a comprehensive list of the names of the years from -422 DR to what will be 1600 DR (the Year of Unseen Enemies), although it is widely believed that the roll of years was created by Alaundo of Candlekeep. Because some of the names of the years went missing, Alaundo replaced these with his own choices. Supposedly, the names given the years are prophecies made by Alaundo as to the most significant event of that year.
The current year is 1489 DR, or the Year of the Warrior Princess.
