Wandering Goblins

Wandering Goblins (渡りゴブリン) were a group of migratory goblins that attempted to form their own kingdom in the Great Forest of Tob.

Background
There are many huge cavities deep underground in the Great Forest of Tob, and sometimes when the earth collapses it shows its appearance. Such caves are home to a variety of monsters, but the cave where the goblins live is one of the most incredible.

Somehow, these goblins have organized themselves reminiscent of ants. The comparison is not wrong, as those who went out from the entrance to their supposed domain carried soil, and those who came in had the blessings of the forest, such as fruits, nuts, edible grass, and even bark. According to information gathered by other scouts, they were growing mushrooms in the cave and breeding edible insects. They had stockpiled enough food to last them the winter without decimating their numbers.

Overlord Second Half Arc
The goblins were observed by members of the Black Scripture from a distance. Seeing that the goblins were forming a highly organized society they prioritized their colony's destruction. One of its members proceeded to summon a pair of Gigant Basilisks to wipe it out.

The surviving goblins numbering about a hundred made their ways to the territory of the Baharuth Empire. They were intercepted by the knights of the Empire and students from the Imperial Magic Academy. After calling a parley, the leading demi-human, a Hobgoblin, told them that they did not wish for conflict. The humans suspicious of why the goblins were fleeing were informed that a bunch of humans summoning Archangel Flames wiped their tribe out. When they revealed that Gigant Basilisks were involved, Fluder Paradyne realized that the Black Scripture was also present. The hobgoblin stated that the remnants would attempt to head south where they heard rumors of a Goblin General and hopefully join the tribe.

Strength
The goblins once numbered to be approximately 10,000 which was akin to as having 10,000 soldiers. In addition to their numbers, and their advancing society, the goblins had the potential to spread their knowledge to the surrounding goblin tribes as well. The dangers these goblins supposed was the skills they accumulated to survive in harsh environments by jumping out of their own tribes and through various tribes. It was believed that given time this band would eventually create their own kingdom if not stopped.
