Our story takes place in Faerun, in 1395. The time of troubles and Spellpurge are still a recent memory, as are the political and economic turmoil that remain. The new generation of Arcane magic users face fresh superstition, with many fearing their abilities.

The Nightingale's Rest is in Arrabar, while 5e seems to refer to this city in the past tense I'll be writing it how I think it would have happened after the Spellpurge caused a bunch of geographical changes.
