This event is celebrated by Imperial priests of St. Alessia every summer in commemoration of the Whitestrake’s slaughter of Elves at the Bridge of Heldon.
Note: this information has been compiled from the PTS notes and the in-game achievements listed under Holiday events. Based on accidental leaks on XBox and the Morrowind Prima Guide, the event is expected to start on July 22nd, 2017.
For the duration of the event, Adhazabi Aba-daro the Golden will also offer gold-quality jewelry in each of the Rewards for the Worthy item sets, in exchange for AP only (not sold for gold.)
By decree of your most majestic majesties,
From the depths of their magnificent magnanimity,
Today begins a rule of foolishness and frivolities!
Abolished are concerns of toil, tax, and responsibility,
For this silly season of winsome glee! — Jester’s Festival Invitation Scroll
