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.

HistoryThe first Sindria was founded when Sinbad was 18, after he obtained Valefor and Baal. The land and infrastructure cost 10,000,000 DINARS to purchase from Parthevia. 
Shortly after its establishment, the first Sindria was caught in the middle of a Parthevian power struggle greatly influenced by Al-Thamen. The fall of the first Sindria left a deep scar in Sinbad and is the reason why he is half-fallen into depravity.
Harvest Festival "Mahrajan"
A few times a year the Southern Creatures that inhabits the waters around Sindria will get past the lookout and come attack the island. It is the duty of the King and the Eight Generals to fight them off whenever they attack. Sinbad turned this attacking of the southern Creatures into a performance. It calms the people's fears and earned them tourist. The southern creature that was killed is an abundant source of protein and it is distributed throughout the country to be feasted on.
