Sindria Kingdom , or rather the Second Kingdom of Sindria, is an island country located in the southern seas. Its realms lie in extreme south of the region that northern mapmakers had labeled 'uncivilized'. These islands were isolated until King Sinbad developed them. The 'City of Dreams' has become known around the world as home of the 'Legendary Dungeon Capturer' attracts many visitors. The islands teem with people, animals and plants not seen in the northern continents due to their unusual topography and climates. As a result, the country has become prosperous through trade and tourism. It was established after the original Kingdom of Sindria established by Sinbad and his companions was invaded and destroyed by Parthevia. ; : : Sinbad is the King of Sindria and the leader of the Alliance of the Seven Seas. Born in Parthevia, he first conquered a dungeon (Baal) at the age of 14, and eventually captured six more, becoming the "Master of Seven Djinn". His achievements led the Djinn to prohibit him from further dungeon conquests. One such dungeon was created by Judar without authorization, which Sinbad conquered to impede Al-Thamen's plans. Following the meeting with Aladdin's group during the trade negotiations in Balbadd, he escorts them to Sindria for the purposes of protection and training. Sinbad, a master of Magoi manipulation trained by Yambala Gladiators, resisted corruption after absorbing massive amounts of Black Rukh from fallen Parthevians. His enigmatic nature and undisclosed ambitions have led allies like Yunan to exercise caution regarding his true intentions. He is in command of the Eight Generals of Sindria, a select group of highly trained warriors who were recruited during his travels. It is later revealed that Sinbad hosts the Rukh of David—founder of Alma Torran's Orthodox Magicians and grandfather to Aladdin. He serves as protagonist in the prequel spin-off series
