Overpol clan was a family that founded and ruled the Overpol Expanse. Founded by Dod Overpol, the clan was known for keeping their private life away from the public eye, as well as using propaganda and ideology to spread their influence to an extent unusual in their time.

Dod /dʌd/ Overpol (19th CSR - 1901 SR) was born in the northern region of Tarnaria. The little that's known about her childhood was captured and mythologized in children's books about “wise Grandma Dod” which became popular in the Overpol Expanse. The tradition has since died out and many books have been lost, but several copies are preserved in Couleds.

The mythologized story goes as follows.

She met and married a superhero warrior known as the Forest Leveler. Their life goal was what they called The Big Adventure, which meant walking the plains and forests of the world on foot. Together they traveled from Tarnaria to the forest near the Taverda river, where they were welcomed into one of the villages. However, several days later the people of the village tried to kill them, because during their stay one of the children had gotten sick and the villagers believed that this was because of the strangers. Fighting for their lives, the Forest Leveler killed several of the attackers and scared the rest away.

Since then they became infamous in the area and people began to avoid them. They set up a small house near the river, which they called Dav, which meant “cornerstone” in bukk.

Dod knew a lot about plants and animals and they soon created a large and beautiful garden, with trees so high that people from afar began to notice the garden. They would come to the house and talk to their inhabitants, Dod and the Forest Leveler, and no one would ever leave without a gift.

Eventually, previous stories were forgotten and Dod and the Forest Leveler were accepted into the local community. And as their garden grew and prospered, some began coming over and buying their produce. And eventually people began building their houses near the garden and a whole community grew around Dav, the house of Dod and the Forest Leveler.

The story then goes on to tell how Dod was chosen to be the leader of the community and the Forest Leveler became its guardian. People flocked to Dav, searching for peace and protection.

What is actually real in the story has not been easy to tell. The story is clearly a myth, but the general consensus is that the narrative might be generally true: that Dod and the Forest Leveler definitely had conflicts with the local populace, but that eventually they had been successful in turning the public opinion around and being accepted into the community. It is also possible that their way to gain power and influence had indeed been through promising protection, due to the Forest Leveler being apparently the only superhero warrior in the area. This tactic became the linchpin of Dod's innovative approach to building influence.

In 1873 SR Dav was already well known down the river as a prosperous settlement full of wonders, more specifically known for its gardens and very high trees. The latter is a curious bit of history, since no evidence of any special type of tree has ever been uncovered, and yet the information appears in several independent resources. It is possible that the “high trees” is a reference to the Dav Garden, which was built on the roof of the Dav Palace and was indeed seen from afar, although the latter had been competed only by 1894.

By the mid 70s of 19th CSR Dod Overpol announced The Expansion, which was essentially an ultimatum of to all of the neighboring areas. The declaration suggested that in return for their loyalty they would fall under the protection of the Overpol clan. The majority of cities and settlements have agreed.

The Forest Leveler had died in 1890.
