The Sumar Empire in The Blue Crystal Rod
The Sumar Empire (スーマール帝国, Sūmāru Teikoku) is an aggressive empire ruled by Balarant located to the south of Babylim near the river Euphrates. When the empire heard about the Blue Crystal Rod in the skies of Babylim, they invaded the kingdom to claim the rod for themselves. They won the war and enslaved the survivors, making them build a large tower to reach the rod. When the tower was completed, the god Anu struck it with lightning, destroying the tower and the Sumarian soldiers inside. Because of the Sumarian's actions, Druaga was able to revive. He rebuilt the Tower of Druaga for his purposes and revived the Sumarian soldiers that died in the tower to work for him.
The Sumar Empire invading Babylim in The Quest of Ki
In The Blue Crystal Rod, the player has the option to use a ship to sail to the Sumar Empire. Depending of the player's actions, Gil and Ki may discover that the empire was being manipulated by the demon Anshar. They may also find that Anshar rules openly.
In The Nightmare of Druaga: Fushigino Dungeon, it's said that the Sumar Empire collapsed of internal strife after the Druaga War. Because of what happened in the past, the people of Babylim had feelings of hatred and resentment toward the empire.
