The Fellnight Realm
At the wedding of Elwin and Kailah, important citizens in the village of Tatzlford, the heroes were settling in for a small celebration. The atmosphere was pleasant; the food and wine were good, and even though none of the heroes particularly wanted the attention, it was good to see people's positive reactions to having such major figures visiting the village. Unfortunately, the ceremony was interrupted by swarms of bees, which attacked everyone present: and when those were driven off and the civilians had taken cover indoors, some strange gnome-like creatures attacked through a wall of thorns. These spriggans, not like their normal kin, had bodies covered in thorns: and then Tenzekil, a former resident of the village, announced that he was leading the attack on behalf of a mysterious Queen Rhoswen. In the aftermath of the attack, a mysterious mist began spreading out of the forest, engulfing the village and reducing visibility to just a few feet.
Investigating, the party finds out that the Fellnight Realm is a demiplane, a prison created for Queen Rhoswen when she tried blending shadow magic with that of the fey. Her attack on Golarion was just beginning: she was in the process of breaking free from her prison, and attempting to carve out a realm of her own. Tracking through the mist, finding their way each time they lost it, the heroes eventually took the fight back into the Fellnight Realm, replacing the wardstones that Tenzekil had removed from the barrier. Tenzekil himself tried to stop the heroes, but was defeated: in despair, he turned his back on Queen Rhoswen, offering what help he could. She had tricked him into service when he came looking for a cure for the Bleaching, a usually-fatal disease suffered by gnomes; the pain of carrying out her task and breaking the wardstone barrier had forced him through the Bleaching and out of the other side. Now, desperate to redeem himself - even if it costs his life - he gave the party directions to the stream entrance to Rhoswen's palace.
Infiltrating the palace via the stream, the party was ambushed by heavy defenses: the dungeon and torture-chamber were guarded by a malicious satyr, who fled upstairs to the main part of the palace. The defenders will now be on alert...
