I had a comment on the previous post about goblins asking about lairs. I've been a little vague on that, referring to them a few times as an underground race but also mentioning that they do some farming and keep some livestock.
A small portion of goblins living in Lesser Poland on marginal land near the Vistula have settled into agrarian lifestyles. They are not the focus of this post. Instead, we focus on the goblins who live along the Carpathians who are semi-nomadic and utilize raiding for a portion of their subsistence. I mean come on, why would the PCs be mucking around with farming goblins? Sheesh...
Goblins settle in out of the way places, in rough terrain where they can hide themselves but still range out and raid when necessary. They will settle below ground in natural caves, abandoned mines, and any other subterranean locale. Goblins rarely work the ground where they settle since they often move their tribes. In addition, they will settle above ground in crevices, escarpments, canyons, and other sheltered areas and erect tenting. Either way, they choose areas that are easy to hide their tribes in, command a view of the surrounding area, and have multiple avenues to escape.
Their economy revolves around periodic raids. Goblins are decent metalworkers, able to break down tools to fashion arrow heads, darts, spears, and other weapons. Otherwise, most goblin tools are made from animal products such as sinew, bone, and hides. Goblins also prize other manufactured and refined products to fit specific needs, especially salt and sugar to preserve food.
Goblins raid along a seasonal pattern. Throughout good weather months, they collect a menagerie of livestock. They focus on animals that are easy to keep, such as pigs, goats, and chickens. Goats and chickens also provide a steady and easy source of food. Larger livestock, such as cattle or horses, are typically worked for a bit, then slaughtered for food and materials. Goblins do not feed and keep animals through the winter, instead, they conduct large slaughters in the late fall and then dry and preserve as much food as they can to last the winter. Once the next spring bring favorable weather, they raid again to replenish their livestock.
Goblin tribes pick up and move as a response to raids, both to search for fresh targets and as a response to retaliatory raids.
