I've just come back to Menewsha after a long absence, and I'm not really sure how to look this sort of thing up, haha. Is there a Christmas event? Or will there be? What information has been released, if any?

There will be an event for the Festival of the Winter Nights. The dates are still not released yet though. ^^

I was wondering the same thing, glad I found this thread. Now know what it is called.
