Although it was possible to search for them using the string "Halloween," I thought it might be useful to have a page which summarizes the Halloween quest information for the seasonal Halloween quests which will become available on October 28. Fanra's EverQuest Wiki has a page dedicated to Halloween, but it didn't provide as much of an overview of the quests as I would like. So, I set up a table of Halloween quests on the wiki here.
Please feel free to update it, add links, or reformat it. I didn't link the quest-givers, although I might do that later. Also, I can't figure out how to make the sorting work properly, so if someone can fix my syntax or figure out how Wikibase is different from MediaWiki, it would be nice to have it sort properly. I probably should have noted whether the quests are repeatable, but you can get that info from the individual quest entries. I also didn't put in maximum level limits because I don't think that DB intends to have any (though in the past they've sometimes been buggy for the highest level players).
Happy Halloween!
