Calamity of Memories

The Calamity of Memories was a magical event that occurred during the Legend of the Leaves campaign in the year of 1486, in which the city of Neverwinter as well as neighboring towns and villages disappeared from reality and from the memories of around 98% of the world's population.
== Cause of the Calamity ==
It is believed that the cause of the Calamity was the inexperienced use of powerful psionic magic by Lena, a prodigy Psion child. According to witnesses, many believe that she was manipulated by Xanathar, the leader of the Thieves' Guild in Waterdeep, in order for him to seize power over Neverwinter.
== The Aftermath ==
A rough estimation of the victims suggests that more than 98% of the world's population suffered from what could be described as "mass amnesia". The ones who survived the Calamity and were alive when the fabric of reality changed, were displaced into new lives; with memories falsified and adjusted in order to preserve their sanity.
=== Those Who Remember ===
Not everybody lost their memories after the Calamity. Cases of people from all over the world who suddenly got their memory back started popping up over time. Confused and unable to cope with a reality they remember but which doesn't exist, many found refuge in the town of Phandalin and the Villa of Leaves, a center for "those who remember" as they were called, led by Soren, a cleric living in Phandalin.
