The adventure takes place below the village of Borgstrand, a small village in the arctic circle. Although the adventure is set in the Legends of Omeria campaign setting, you can just as easily place it in any campaign setting that includes an arctic region subjected to polar nights.

This is the third chapter of the adventure series, They Came From Beyond!, Tunnels of the Simulacra and immediately follows the second chapter, Village of the Absent Sun. You can access the first two parts of the adventure on both DMDave’s Patreon and Roll20.

Background

Five years ago, a family of remorhazes tore through the earth below the village of Borgstrand, creating a series of tunnels and caverns. Fortunately for the Borgstranders above, a group of adventuring drow entered the tunnels and cleared the remorhazes out before they could do further damage. In time, most of the Borgstranders forgot about the tunnels. And then the green flash happened.

Recently, a wicked dimensional traveler named Doctor Calamity arrived in the forests north of Borgstrand and took residence in an abandoned monastery. The bright flash created by his arrival drew the attention of the Borgstranders who sent a retinue of hunters to investigate. Calamity and

his minions killed the hunters and replaced them with clay golem simulacra. Then, the simulacra returned to the village and started to replace more Borgstranders with simulacra. The faux Borgstranders used the old remorhaz tunnels to move between locations and draw their victims into the dark in order to replace them.

At the conclusion of the last chapter in the They Came From Beyond!, the adventurers discovered this dark plot and learned that the simulacra were working below Borgstrand. This adventure picks up right after the characters enter the caverns.
