When the rest of the group emerges from the inn and joins Jak, the sun is nearly directly overhead. Impatient, the trusty leads the group out of town through the throngs of shoppers and travelers to the outskirts of town. There he bids them farewell abruptly and turns back to town.
The group makes their way into the windswept badlands known as the Sumber Hills. The going is slow, as much of the surrounding land is comprised of hills with exposed rock faces or steep escarpments. More than once it becomes necessary to detour around a particularly treacherous hill, or a deep ravine.
Tiny streams rise from numerous hidden springs, and the drinkable water is welcome relief from the intensifying sun. Thunder booms in the distance as the afternoon continues on, but no rain falls nearby. Despite scanning the horizon for any other travelers or movement of any kind, they encounter no one for several hours.
As the afternoon deepens into evening, the group reaches a ravine that matches the description of the location of Tricklerock Cave. Looking down into the shallow gorge, an exposed rock face is split by a vertical crevice about three feet wide and fifteen feet high. Water trickles from the opening and spills into a nearby bog.
The Dessarin Valley map updated. You've been travelling for about 4 hours, and the sun is beginning to set.
Feel free to make perception checks as you like.
