I'm running a nautical campaign and would like to hear other people's suggestions on what would Gloranthan nautical flags look like? Would the merchant ships fly their own city's flag, or their national flag? I'd need the flags for the Quinpolic League, Seshnela before Nolos left, Holy Country's Navy, Nochet, Rhigos, Esrolia, Heortland and Shadow Plateau. And Jrustelan Vadeli flags.
Quinpolic league could perhaps have five city gates on a blue background. And Holy Country's Navy's flag could be divided to six parts, each with different color. For Shadow Plateau I'm thinking grey or dark blue with Night Rune in the center. Esrolia's flag could be green with a copper colored Ernalda in the center.
