Winter event
I come at coldest winter to bite and gnash and gnaw. People of the Fremennik, fear me. I am Hati, and I will devour the moon, and my brother, Sköll, the sun, and thus will begin the End of Things. – Fremennik folk tale
The Winter event first occurred in January 2011. At this time, players only had the opportunity to defeat Hati. The following year, in January 2012, players received a second opportunity to take down Hati, and this time, his brother Sköll as well.
