The road less traveled
Garvin Wanderer and Snapper head out from the rest of the group, each charting a path to take them up along the opposite edges of the canyon. Each take care to stay hidden and quiet and soon are out of sight of their companions (OOC: Taking 10 on Stealth checks).
There are no paths on either side of the ridge, although the ranger has a much easier time threading his way through the underbrush (OOC: Thanks to his ranks in Survival) while Snapper keeps on getting caught on branches or nettles. Because of this Garvin gets ahead a bit and reaches sight of Mistamere within fifteen minutes or so.
The ancient keep is built directly into the side of the canyon walls, at least two hundred feet below Garvin's current location. It is a simple keep and bailey affair. The curtain walls is in horrible shape with many large holes in it, although the main doors still seem to be in decent shape. The keep used to be at least two stories but the top stories collapsed and now lie in ruin. The courtyard of the keep is currently empty and both the doors of the bailey look closed, although it is hard to tell exactly from the current angle.
Snapper finally catches up to within sight of the Keep and notices something else: hundreds of tracks around him. Squatting down to get a closer look and judging from their size and shape, they seem to have been made by giant rock geckos, which are quite common in this part of Varisia (OOC: Untrained Intelligence check 10 + 2, vs DC 6). Nearly the size of a horse they are expert climbers, but are generally harmless if left alone.
