After reading the Sanctum city-state page, which was really well put together, I went to view the Polis page. I found some parts to be pretty vague or non-existent like the Trikru/Trishanakru/Azgeda embassies or that Polis acts as a place for trade among the coalition. The underground tunnels, the tower acting as a beacon to send a message long distance like when Indra finds out Lexa is dead in S3 e9, and the law that weapons are not allowed within the city or hunting in "the Commanders woods" S3 e5.
Sorry if this comes across as negative, and my knowledge of how a Wiki page is constructed isn't very good.
