Foren

Foren is the largest island of Eiselcross and the site of the ruins of Aeor, which makes it 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 and wild magic in the area, such as the perpetually flowing river of lava that bisects the island. Teleportation to the area is disrupted as well. The river arises near the center of the island at the "flow change" and flows both northward and southward from that point. The magical disruptions are the strongest within the ruins of the city of Aeor.

In 836 PD, an ancient ritual circle appeared on Foren island. It dates back to the Founding and appears at places in the world at "odd times", then disappears after transaction is given, and appears somewhere else in the world spontaneously. Travelling toward the A2 crashing site of Aeor, the Mighty Nein were caught into an ice storm and spotted a group of seven statues of a human, gnome, elf, goliath, halfling, orc, and dwarf encircling a low pedestal. Caleb detected an intense aura of divination magic from each faintly warm statue. When Jester to rose on the center platform, the statues' eyes looked into hers and voices filled her mind, saying: "Do you give to receive? Ask, and we take." She was unable to move and realized she must ask a question: "What are the Tombtakers trying to bring back?" Their eyes glowed, and she saw a vision of Cognoza in the Astral Plane and the Tombtakers traversing the Eiselcross. As the vision ended, something was pulled from her, and the party noticed she looks about five years older. The circle disappeared when they turned away.
