Up until now, it hasn't really struck me how much the goblins have been left alone by the local adventurers guild.
They had female human captives right at the start, then the older generation attacked a caravan and captured more female humans.
Then the whole human adventurers party got wiped out and eaten a couple of episodes ago, although the guild would have no idea why that happened.
Those are the type of things that usually initiate beginners/low level "Stomp The Goblins" type quests to be posted on the guild's job board, followed by a steady stream of low-level adventurers hoping for some easy cash and leveling up past these type of jobs.
Anyway, the goblins are leveled up into fancy clothes to go with standard adventurer abilities, and get to fight a human troop of soldiers next.
