It's time for our november party, and since it's fall festival, it'll be a costume party.
You are expected to costume either as an animal (=those creatures obviously based on rl animals) or as an other adventurer.
Another event is already scheduled for next friday, so it will be saturday, 11pm middle european time. Thats either 5pm or 6pm EST, depending on whether you still have summer time/daylight savings time/whatever you call it.
