United Municipalities of Loodon were a group of cities, villages and settlements which in the middle of the 18th CSR have united to be able to better defend their lands, but were overrun by Kareden several years later.

The central city was Oyangaltans, located at the mouth of the Loodon river.

Loodon started by copying the model of the United Municipalities of Loodon when they organized a cooperative up the river.
