The **Second Great War** (15 Narvinye S145 - 2 Yavannie S150) is a conflict between Kun Muldor and the Grand Alliance of Zemuriah against the Ataranic Empire. It took place in Valderia and in Zemuriah. It is one of the bloodiest conflicts to rage over Esgrea, and the first time that the dragonflight participated after nearly 10,000 years of being calm at the peak of Mt. Redorian.

The war was driven with an Imperial ambition of the Ataranic Empire, who, after claming several lands outside of its borders, decided to further its influence in Zemuriah. For nearly 2,000 years, the Ataranier government wanted to claim lands in Zemuriah but were prevented due to the presence of the Thalassian Elves, who were exiles from the Kingdom 10,000 years ago. Ataranier also wanted to claim more land in order to boost its already large economy and to increase land space to surpass Kun Muldor.

The war began in 15 Narvinye S145, when the Ataranic Elves invaded Arracourt, with the capital capitulating later of that year. Septia was conquered next despite threats by the pope to excommunicate Ataranic Elves who were members of the Holy Septian Church. It failed and Septia easily fell. The invaders later focused on Onth'Thalas, the nation of its exiles. Hloirëon Andúnener had a goal of reconquering the Thalassian Elves under a perception of punishment for the latter's insolence. Prior to the invasion, the Thalassian Elves fled east to the safety of Mondstadt or Veldrun. Led by Hadvar Suntorry, 90% of Onth'Thalas' population successfuly fled to the Redridge Mountains, and through the safety of Veldrun. Those who remained defended Silvermoon and the Sunwell to the last man. In the last act of sacrifice, Revalor ordered his brother to muster the power of the Sunwell to destroy it, as well as the entirety of Silvermoon and Eversong Woods. From the safety of the Redridge Mountains, Hadvar successfully detonated the Sunwell, imploding everything around it, including the Elven capital and the Sunwell, resulting it in being uninhabitable.

Despite defeating the Thalassian Elves, the Ataranic Elves failed in its objective of conquering Onth'Thalas and the Sunwell, and subsequently turned its focus on Veldrun and Mondstadt. By the 3rd year of the war, Eristrasza was beginning to show signs of warning towards the Ataranian Elves and their quest for a global domination of Esgrea. Signs that she was coming out to help Zemuriah's defenders first showed when a massive earthquake shook several regions of Ferrariah. Later, Mt. Redorian erupted, causing crop failures throughout Esgrea. And finally, during the climactic Battle of Windheim, Eristrasza and the rest of the dragonflight went out of their temples in support of Zemuriah's defenders. In Mondstadt, during the harsh Mondstadt Winter, the Ataranic Elves were not prepared for its effects, and thus were forced to withdraw from the Mondstadt Region.

The war began to be disasterous for the Ataranic Elves as they were slowly being beaten back by the combined forces of the Grand Alliance. Following the Battle of Blummenberg, the defeated elves were forced to go on the defensive for the rest of the war until its end. The end of the war damaged the Ataranic Empire's prestige, as the Royal Veldrunian Navy and the Royal Thalassian Navy began to slowly control the waters around Zemuriah.
