So from what I heard this event is dedicated to Flyleaf who recently passed away after a long fight cancer which made him weak and when his stomach got blocked he couldn't handle anymore...
I'm very sorry to hear that, it's the first time when I hear about him and I already feel sorry for his loss... May he rest in peace...

I found this event on the game yesterday and also this big circle of deer that made me think about a sort of a great, meeting, hence the title.
So here's Koanluq (my stag) along with many other deer (that I don't really recognise) in a snowy night.
I have more screenshots of this event, if you want to see.
