The Last Days of Dwarovar refers to the time during the long decline of Aul-Dwarov and ancient dwarf civilization as a whole. This period was rife with infighting between holds and was the final nail in the collapse of Amldihr's authority and thus Aul-Dwarov's authority over the dwarven people. The start of the Last Days is usually correlated with the rise of the orcish race which is estimated to be around 6000 BA. Ironically, the Last Days of the Dwarovar did not last a few days, but thousands of years - and is said to have only ended after the first dwarven hold was reclaimed after the The Greentide.
The most critical part of the Last Days was the fall of Er-Natvir which was the central hub of the Dwarovar Railway.
