The Horseman Rises: Hallow’s End is Nigh!

It’s time for Tricky Treats, costumes, and—of course—the return of the Headless Horseman. Hallow’s End is here!
Hallow’s End celebrates the break of the Forsaken from the Scourge.
Fun and mischief reign as the Innkeepers of Azeroth give treats (and tricks) to whomever asks.
The spookiest time of year has arrived once more, and the Headless Horseman rides forth to strike terror into the hearts and minds of Azeroth’s citizens.
When: October 18–November 1
Where: Trick-or-Treat throughout the inns of Azeroth, Northrend, Pandaria, Outland, Draenor, and the Broken Isles (Dalaran) for tasty treats and currency to buy Hallow’s End delights.
All together now! The Headless Horseman is back to set fire to Razor Hill and Goldshire once more. You’ll need to lend a hand on the bucket brigade to put them out and face the infamous rider.
It would be a lovely time of year to take a stroll through the Scarlet Monastery’s Graveyard if the Headless Horseman hadn’t decided to make it his new lair. If you're lucky and succeed in routing this menace from within, you may ride off with his steed.
Throughout Hallow’s End, characters level 23–110 will be able to queue up for this ghoulish encounter in the Dungeon Finder.
