Sindria Kingdom (シンドリア王国, Shindoria Ōkoku) is a country established and formerly ruled by King Sinbad. Sinbad has founded the Kingdom of Sindria when he was 18 years old after establishing an agreement with Parthevia.  The old location of the Sindria Kingdom was destroyed by Parthevia and Al-Thamen which leads the country to relocate to the southern sea.  After his abdication, it is currently ruled by Drakon.  The Sindria Eight Generals retire after some of them have to take over their parents' spot as rulers of their respective countries due to their parents taking up roles in the International Alliance. Sindria Kingdom is a part and leading country of the Seven Seas Alliance and now currently located at an island in the southern sea.
Sindria is a large island with several smaller islands surrounding it. It seems to be surrounded by a tall rock wall.
