It is possible that the location where this vision was held is in reference to the great chain map that they found within the temple of Emissary.
Here the map details a location which is now a known location of a Peian Monastery
In the morning on the 18th of Suntide, the party ventured southeast, following the river in an attempt to track the 'white tiefling'. They came across a trail of hunted-down animals and followed them to what they discovered was the tiefling's camp. The camp was decorated with trophies; animals and humanoids alike on spikes. There was a very vibrant spider that wielded a violet scarf and seemed both protective and nervous.
In a chest within the camp, there was a picture of the 'white tiefling' from long ago. He looked cleaner, younger, and more civilized. With him was a pale tiefling woman with a scarf similar to the one the spider had. The party discovered some other loot in the camp as well.
As the tiefling was nowhere to be found, the party decided to camp out at the nearby lake. Draz went hunting, and Arkorow and Devinn went foraging and potion crafting. Mordus, while searching for firewood, discovered a quiet glade with lots of buzzing bees and fluttering butterflies. A spirit here by the name of Polly asked him to reunite her with her beloved knight, Dandelion. He took on a ring found in the glade, and her spirit is following with him now.
Returning to the tiefling camp at night, Devinn, having recharged the Twilight Eye of Murk, saw into the past and future to help discern the location of the white tiefling and if he would return. It appeared he would not. At their lakeside camp, the party received ominous dreams and visions.
Arkorow and Draz shared a vision, where they found themselves in a temple or other location devoted to Peios. With them were Duke, and two caithuna called Spiritbrook. They were barricading a massive door while letting Arkorow, Duke, and Drazvik escape safely.
Devinn had yet another dream in which he was another person, accompanying the same tiefling woman. They were fleeing from a group of people on horseback attempting to hunt them down. Mortally wounded, they summoned an ebony stallion with a fiery mane that dragged them and their wagon to safety at high speed.
Mordus had a vision and found himself somewhere on a cliff in the Elven Aristocracy, his field of view as someone else. She was being chased by figures, each with a weapon very much like Mordus' falchion. His vision ended as she brandished her sword as one of the figures chasing her yelled out, "End of the road, Ulmarra!"
