Unencumbered by a physical form and all but undetectable to mundane beings on this plane, Kearnos is able to scout out and explore the camp at his leisure and take a full and total accounting of it's contents and layouts.
In the northwest quarter of the ring is a stack of crates and some barrels being unloaded from a wagon by a pair of bugbears. They tear off the lid of each crate to verify its contents before putting it in the pile, and Keranos is able to see that each is filled with glass vials of brown fluid labeled with a smiling cartoon tuber. Each crate is branded with "Nocbus Trading Company, Landsend."
In the southwest quarter are seven cages. They are relatively crude in their construction, but are apparently strong enough to contain some very formidable creatures, because each one contains a large animal barely afforded enough room to sit down in. Among their number are a constrictor snake of some sort, a giant scorpion, a saber-tooth tiger, a giant boar, an owlbear, a giant eagle, and a giant ape. They are all in various states of agitation, but nothing that would seem out of the ordinary for a captured wild animal stuck in a cage. The eagle in particular does not seem to be coping well with its confinement and spins endlessly in its cage, trying at the spots where the bars are forged together with its hooked beak. Interestingly enough, there are a pair of iron loops on the tops of each cage, like what one might expect for being loaded and unloaded with a block and tackle from a ship, perhaps. There aren't any cages that could contain Sagishi; he'd easily be able to slip through the bars of these ones. It's worth noting that the locks aren't particularly sophisticated. More than enough to keep the animals in, but nothing that would keep even an apprentice locksmith out for more than a moment.
The eastern half of the ring seems to be dedicated to shelter and training of the goblinoids. There are some tents and a firepit, near which a trio of goblins are working to feed and water not only three dire wolves, but three regular wolves as well. A little to the south of them, a pair of hobgoblins are training together near a small archery range and a rack of crude--but doubtlessly effective--weapons and tools.
At the center of the compound is a tower platform, upon which stands a wiry hobgoblin clutching a quarter staff in his grip. As the disembodied eidolon of Keranos floats by, his head snaps in that direction, his piercing golden eyes staring straight through the invisible presence unseeing, but wearing an expression of wary suspicion none-the-less.
A tiny fox could doubtlessly enter unobserved, but staying that way might be another matter. There's a lot of open ground and not much cover, and there're fully six snarling wolves and dire wolves who could potentially detect his scent if he draws too near. Sagishi could potentially enter from the north and be able to dart either east or west to put himself behind the tents or the supplies respectively, but moving much beyond that is risky. If he entered from the west or the south, he would conceivably be able to avoid attention by moving among the caged animals, though there's no telling how they'd react to his presence. Coming in from the east would be suicidal, as that would almost certainly put him in plain view of the wolves, the goblins, and the hobgoblins with them being as close to that side of the compound as they are.
((Dat critical perception check. Basically, Keranos know knows everything there is to know about
this map.
Speaking of maps, re: SoF's question, you guys are in the hex immediately to the southwest of the one that had the tree))
