Myos (pronounced MEE-ohs) is one of the Ersas city-states, a major port on the Ten Thousand Islands within the Sea of Ersas. The city is split into two broad sections - the wealthy neighborhoods of the Heights are built into the side of the mountainous island, while the laborers and common folk of the city largely live in the Flooded Reach, an isthmus that extends from the island into the sea. During high tides the Flooded Reach is split into three separate neighborhoods that turn into their own islands, accessible only by boats and ferries that simply rest ashore during the low tides when the rocky seafloor is exposed and becomes walkable.
Myos is a navarchate, a type of merchant republic common in the Ersas. Its current ruler is the renounced sailor Hippolus.
