LOST CITY
One key aspect of
Icewind Dale: Rime of the Frostmaiden involves the discovery and exploration of an ancient Netherese city buried under the ice. Netheril is one of the Forgotten Realms’ lost empires. Its wizards were unsurpassed in their expertise, and their magic rivalled the gods, which is ultimately what led to their hubris and their demise. “A necropolis buried under the ice is a type of location we’ve never visited before,” Perkins says, describing the city as Atlantean in its feel.
