The Marine Forest

East of the Brokelands and Iron Gardens, the rusted urban sprawl gives way abruptly to miles of dense, thriving forest. The Marine Forest stretches to the shoreline in places and grows inland like a living wall between Old York and The Mass, a boundary drawn not by politics but by nature. Rivers, lakes, and ponds thread through the canopy, and a complete ecosystem flourishes beneath it: from insects and small game to large woodland cats, bears, and wolves.
 

The Greenwood Ghosts

The forest is the domain of the Greenwood Ghosts, a post-primitive Natural One tribe that travels in small family groups through the trees. They are rarely seen and widely considered a legend by outsiders. Those who dismiss them as ghost stories tend to be the same people who never come back from the woods.
 

Silence and Stone

Trespassers who enter the Marine Forest are never heard from again. The only evidence left behind is a neatly piled set of stones with the victim's worldly goods buried underneath and their weapons left fully loaded on top, arranged like a small pyramid. The message is unmistakable: the Ghosts did not even need the weapons. They struck so silently that the trespassers never fired a shot.
  The forest allegedly despises technology. Traders and caravaners report that those transporting electronics or high-tech equipment into the woods vanish with particular reliability. Whether the forest itself or its inhabitants enforce this rule is a matter of debate, but the result is the same. Some claim that bribes or Natural One intermediaries can arrange safe passage through hidden pathways, but confirmed successful crossings are exceedingly rare.
  The Marine Forest is the one border in the Nor'East that no army, gang, or caravan has crossed by force. The trees do not negotiate.
