The Iceberg of Rime and Ruin

Publisher's blurb: Strange creatures with draconic traits have been attacking travelers along the northern Sword Coast between Luskan and Ironmaster, both on land and at sea. The creatures were first sighted after a mysterious iceberg, constantly shrouded in a cold fog, appeared off the coast near Fireshear several ten-days ago. A call has gone out for brave adventurers to investigate the iceberg and discover what the connection is between it and the strange creatures that are being called “the dragon-blooded”.
