When Leetham retired, Gnarl was unwilling to live in a town full of humans as Leetham’s good will was not enough for the townsfolk to treat him with anything but the most forced cordiality. He set out to the dwarven mine nearby where he came across a hand full of remaining goblins that had recently been raided by burgeoning adventurers.
Gnarl took who was left and continued until he found the valley floor where he took them to a parcel of untamed wild they could settle in. Leetham assisted at first by dropping off supplies they needed, but never told anyone in town of the goblin village. Gnarl wanted these goblins to have a life like he had seen while travelling with Leetham. He had Leetham bring books for those that could read on tending crops and taming the land. They built a miniature town with stone and clay walls. They have textiles, pottery, and livestock. Everything they could need, and a safe hiding place from most of the world. It is the safety of the location and the shadow of nearby Black Top Mountain that inspired the name Shadow Haven.
Currently Gnarl’s son, also called Gnarl has taken up the charge of running the town with the advice of the village shaman. The shaman is also the head of the council of elders that make the more mundane decisions and are always consulted on major decisions. More so than before since Gnarl’s death.
