The Three River Delta was the largest plain as well as the granary of Tianjing Basin. It was fertile and the most densely populated.
It occupied ten percent of the land area of Tianjing Basin, but fed one third of the population.
In this area, a total of seven cities dotted the plain like seven pearls. These seven pearls were under the control of the three major factions.
Recently, the three major factions were converging their forces on this area. This made the commoners living near the Three River Delta jittery as they wondered if there was going to be war again.
A few days later, the news gradually spread among the commoners of the Three River Delta that there was really going to be a war. It wasn't between the three factions, but was them against the aboriginals.
