Seasonal events: Underwhelming?

[Deathgasm]

As someone else pointed out, Christmas was originally a Pagan celebration of the Winter Solstice. The church co-opted it. There's no reason it wouldn't happen on Eorzea since Winter still happens.

Same with Halloween. It was a celebration of Harvest. Unless nobody farms or harvests crops in Eorzea, there's no reason not to have it.

You should read what's between the comment you quoted and your answer
There are two opinions about Halloween 1 - celebration of harvest, 2 - It comes from the Gaelic Samhain, Samain as we write it in France, ex-gaul, despite most historians believe more in the second one, we still have no, how do you say in english.. certitudes in french.

Peeps, before talking about this world and what fits to the lore or not, please learn about it first, the debate will be much more interesting if we all limit ourselves to speak only about what we know, thanks
