Sinister Secret of Saltmarsh

Producer letter/February 2021: ''This summer will see the release of the first "mini-expansion" in Dungeons & Dragons Online in the form of the Classic Adventure: The Sinister Secret of Saltmarsh! An evil Alchemist's mansion stands alone on a cliff and mysterious lights and hauntings have kept people away despite rumors of great treasure.''

The intent is for Saltmarsh to be level 3(ish) on Heroic and 32 on Legendary. 

July 21, 2021 is the date of discontinued support of Windows XP and it might coincide with the release date (of this thing).
