History of Aglarond The nation of Aglarond was created in 1065 DR when the half - elf army of Brindor Olósynne defeated the human army of Queen Indrila Demaz at the Battle of Ingdal ' s Arm . The half - elves negotiated for the creation of a new nation with Brindor as its king . Early history . Prior to the creation of Aglarond , the peninsula on which it lies was completely covered by a dense wood known as the Yuirwood , inhabited by the Yuir , a race of wild elves . During this time , drow and mountain troll attack and civil conflicts contributed to the decline of the Yuir , and with it , the decline of the Yuirwood . Although human s only sparsely inhabited the coastal areas of the region , the population of fisherfolk increased in 756 DR , leading to the founding of the settlements of Corth , Ingdal ' s Arm and Velprintalar . As more settlements were founded and the human population increased , they encroached onto the wooded territory of the Yuir elves , also home to a number of satyr s . The human population offered rewards to adventurers who could go into the Yuirwood and eliminate those hostile to the human expansion . By 880 DR , the outer Yuirwood had been cleared , and some time afterwards , humans had reached the interior of the wood . By this time , the Yuir elves were in drastic decline , with only a handful of villages remaining . They were diseased and suffering from the effects of the wars they were fighting . The humans offered to help in their battle against the drow and mountain trolls , eliminating much of the threat . Eventually the humans and Yuir elves produced offspring . This produced a race of half - elf descendants of the Yuir elves , who were proud of their heritage and elven traditions . The humans continued to push back the borders of the Yuirwood , expanding their settlements and farming the land . Eventually the half - elves began to object to this ongoing encroachment , but the humans did not listen to their protests . This drove the half - elves to attack the humans , driving them back to their coastal settlements . The culmination of the conflict occurred in 1065 DR when the half - elf army of Brindor Olósynne defeated the human army of Queen Indrila Demaz at the Battle of Ingdal ' s Arm . The half - elves negotiated for the creation of a new nation , Aglarond , with Brindor as its king . Some humans elected to remain under the rule of the new half - elf monarchy . Others migrated to nearby Altumbel , while others still moved to the Fang , a rugged area . Reign of Brindor . Under King Brindor Olósynne , Aglarond created its very own army . He was responsible for the construction of the fortress Emmech ( later renamed Undumor ) and the citadel Glarondar , as well as the Watchwall . Raiders from Thesk were successfully repelled using Emmech . Brindor reigned until his death in 1128 DR . Reign of Althon . Althon Olósynne succeeded his father Brindor as King of Aglarond , taking the throne in 1128 DR . He vastly improved the security of the nation and repaired much of the damage done to the Yuirwood . Althon , by then known as Althon " the Old " , died in 1189 DR . Reign of Elthond . Elthond Olósynne , Althon ' s eldest son , came to the throne in 1189 DR . He was killed at the hands of invaders from Thay in the Battle of Singing Sands in 1194 DR , just five years after his coronation . Reign of Philaspur . In 1194 DR , the crown passed to Althon ' s second son , Philaspur Olósynne . He reigned for just three years before being killed , again by Thayans , at the Battle of Brokenheads in 1197 DR . Reign of Thara and Ulae . In 1197 DR , Philaspur ' s twin daughters , Thara and Ulae Olósynne , the Gray Sisters , assumed joint power in Aglarond , as Mage - Queens . Thara , the elder daughter , who was skilled in magic and diplomacy , married Elthar of Milvarune and formed a bond between Aglarond and Thesk . Ulae , the younger daughter , who was skilled as a military leader , married a forester : Ilion . Both sisters died within days of one another in 1257 DR . Reign of Halacar . Halacar , son of Ulae , took the throne of Aglarond in 1257 DR , becoming the first full human to rule . In 1260 DR Halacar led a campaign into Thay against the Red Wizards . This was entirely catastrophic : the Aglarondan troops were forced into a retreat , although they managed to repel the oncoming Thayan tanar ' ri . Halacar was poisoned by persons unknown and died in the same year . His death is widely believed to have been instigated by the Red Wizards . Reign of Ilione . Ilione , a powerful spellcaster and Halacar ' s sister , took power in 1260 DR . During her reign she rebuilt Aglarond ' s military strength . She died of a plague that swept through the Inner Sea in 1320 DR . Reign of the Simbul . Ilione had named a female apprentice known as “ the Simbul ” to be her successor . The Simbul quickly made a name for herself as an incredibly powerful sorcerer , with some reckoning her power to be on the same level as Elminster Aumar and Khelben " Blackstaff " Arunsun . The Simbul is one of the Seven Sisters , often leaving her homeland for extended periods of time .
