Neazzarack Realm
From Jenny Everywhere Wiki
The Neazzarack Realm was one of many universes where a version of Halloween existed. However, instead of an enjoyable celebration of spookiness, it was a deadly serious affair, “a time of great fear and terror as the Spirit King Wrythk perform[ed] his annual Halloween ‘returning-from-the-Underworld-to-wreak-havoc’ party piece”.
