((Assume the details of this event occur a couple of in-game hours before the actual event.)) 

A group of large creatures sailing the night sky have just landed a couple of leagues from Chur Gathos that lies far to the north. No matter where you stand outside in Thay, in the distance you can see several pulsing lights going across the horizon where they eventually descend down near the snowy city. Who or what could that possibly be and who will find out? 

((This DM event is open to all PCs and will begin on Saturday December 23rd at 4:00pm EST. Anyone interested can gather inside the Holdfast Inn in Chur Gathos.))
