- The dwarf realm of Ammarindar is overrun by lingering horrors unleashed by the Netherese of Ascalhorn.
- The city of Zhentil Keep launches a military campaign to deal with the growing problem of renegade liches roaming the city at night (also known as the period of the "Night Plague").

A brief alliance with the humans dwelling along the Delimbiyr and the dwarves of the Forlorn Hills founders because of lingering suspicions about the role of humans in the fall of Ascalhorn, later to be known as Hellgate Keep. This alliance is dubbed the Fallen Kingdom (the same name already given to Phalorm), much to the confusion of later historians.
