Eiselcross

 lies north of the Greying Wildlands of Wildemount in the Frigid Depths. It is a group of imposing icy islands, known collectively with the Wildlands as the "Biting North". The site of the crash of the Pre-Calamity floating city-state of Aeor, it is the location of multiple strange artifacts and powerful beasts.

Description
Eiselcross is considered part of Wildemount overall, but it is a frozen arctic area separated from the mainland by the Frigid Depths.

The ballista used in Bazzoxan was partially constructed from "something" recovered in Eiselcross.

Geography
Eiselcross contains two very small ice fishing villages that are expansions of the Dwendalian Empire. Aside from those, it is mostly uninhabited and unvisited. It consists of a collection of eight icy islands, some of which have small, snow-covered mountains ranges:

Beissel
The third largest island, it is also the farthest north, and the home of white dragons.

Dampfkan
The location of an active volcano.

Foren
Eiselcross's largest island and the site of the ruins of Aeor, it is a magnet for treasure seekers. For that reason, mages of the Cerberus Assembly maintain a fort there called Balenpost, and mercenary explorers of Uthodurn populate the small settlement of Syrinlya. One of the Aeorian artifacts was responsible for transforming a frost giant castle into the Fortress of the Dead Jarl around 635 PD.

Vess DeRogna stated that Aeor's presence has continued to weave unchecked magical oddities in the area, such as the perpetually flowing river of lava that bisects the island. Teleportation to the area is disrupted as well.

Frostbogen
Little is known of this island save that it is incredibly dangerous.

Gelier
Eiselcross's second-largest island, it holds the body of Quajath the Undermaw, and its wormkins.

Kaltsel
The smallest of the islands, located southeast of Foren.

Schneescel
This small island lies southwest of Foren.

Taergoss
Eiselcross's second smallest island is a favorite spot for fishing vessels to anchor overnight.

Fauna
Eiselcross holds many creatures that have spent a millennia or more living there and are extremely dangerous.
