Nilma Oordar was the son of Maksag Oordar, his successor as ruler of Mantar, a title he later lost to his wife Gorona, but which he regained later in life, becoming the ruler of Mantar once again. In that capacity he became known as the Angry King who declared Mantar as the superior Xaewoon Blue state, instigated religious cleansing and attempted to invade Qep.

He was the father of Rodare, who was also Kren Oordar, founder of the Oordar clan.

Nilma became ruler of Mantar in 1542, as he turned 12. Maksag died in 1543, leaving Nilma as the only Oordar. Nilma, however, was supported by a strong team of advisors and politicians, loyal to Maksag and Kren, and originating from all parts of the Oordarian proto-empire, which provided Nilma with a vast network.

Nilma's ascension was viewed as the direct and legitimate continuation of Maksag's rule and did not change the stability, established in Mantar by his father. Surrounded by the same people as his father, Nilma felt little interest in making any dramatic changes and instead maintained the status quo. He did, however, express interest in propping up the role of religion early on, something that would become the definitive feature of his later rule.

He developed a good relationship with Kren the Younger and in 1545 SR brokered peace with Qep, sealing it with marriage to Gorona Toarlameek, daughter of Lora's lafit Taley Toarlameek. This demonstrated Nilma's skill as negotiator and strategist, probably at least in part due to his advisors and their understanding of the power dynamics in Qep: negotiating with Lora instead of Qep city undermined Qep city's government and later helped secure Toarlameek rule over the region a decade later.

Kren was unhappy with Kren the Younger's and Nilma's friendship and eventually convinced his son to remove Nilma from power.

In 1547 Kren the Younger staged a plot in the name of several Nilma's key advisors and supporters. The plot involved the independence of Goolkoon, a large city, formerly city-state Goolkoon, which was conquered by Mantar half a century ago and which was still the least loyal to Mantar. Nilma chose the strategy of diplomacy and installed Gorona as Goolkoon's lafit, someone with Qep's lineage, so as to ease the tensions and reduce the appearance of oversight, learning from Kren's and Maksag's mistakes at Or. Gorona was thus put in a position to uncover the alleged plot.

At that time Kren the Younger organized a visit to Mantar and he stopped at Goolkoon, which was geographically closer and made sense. As the plot was uncovered, Kren had Gorona lure in the alleged perpetrators to Goolkoon under the pretense of a celebration of Krenthe Youngers visit and had her arrest execute them, thus murdering most of Nilma's loyalists.

When Nilma had learned of the situation, he immediately arrived to Goolkoon. He had a meeting with Kren the Younger behind closed doors. Nilma later claimed that Kren the Younger accused Nilma of being behind the plot in order to undermine Tonaran's rule. He then cut off his relationship with him. In Tarnarian culture being cut off from the head of the family usually meant a death sentence, but Kren the Younger said that Nilma's life will be spared because of his father, Maksag. However, Nilma was to pass on his title to Gorona and tell her he does so willingly out of embarassement. This later point was a source of particular humiliation for Nilma, one that he never forgave Kren the Younger.

Nilma seemed to have immediately realized what had happened, since he was well informed about Kren's dislike of him, but was unable to do anything to counter the move due to his immediate and complete loss of political power. He was, however, able to slowly rebuild his influence in Mantar over the next two decades, becoming Gorona's unofficial advisor and a shadow figure behind many events in Mantar and Qep.

At some point in the 1570s Gorona had learned the truth, but refused to side with Nilma against Oordars and went as far as to remove him from the court completely, as a sign of loyalty to Kren the Younger.
