It does. The game is set in a world where goblins are basically a plague. They're your standard fantasy "horde" monster. Small in size, green, and in mass numbers they overwhelm villages, steal whatever supplies they can, enslave the men, and drag the women off to rape for breeding. It hasn't been a major focus as of yet, but the adopted sister of the main character escaped from a village as it was being overrun by goblins. So far the looming threat of the goblin hordes has been brought up occasionally, with one section of the game being in response to the fears of a nearby village spotting one. The MC's father also travels from village to village for various reasons and I think one of the things he's on the lookout for is the threat of goblins. Within the confines of The Corruption of the Village there has been no indication that the corruption of the village has anything to do with goblins, but goblins certainly are the unseen threat lurking just outside the events of the game so far.
