Anyone know when the next one usually comes around and what it is?

I think it's Alegarten.. which is the beginning of October; I feel like I'm forgetting something during the summer but maybe not. Who knows, they might have an event or something during the summer

There aren't any summer holidays, but theres often stuff to do Last year was a plot, before that there was a restock war.

Keelhauliday in September is next.

There might be a reading drive too.
