On August 9, the first Siege War took place after the conclusion of server transfers. While the Notongsu Alliance currently holds a higher total number of castles across all servers, the The-K Alliance has secured more castles in key battlegrounds, leading to a tense standoff between the two sides.

In Astaire, where the main force of the The-K Alliance transferred, the result was a clean sweep of all three castles. Despite the efforts of Notongsu Alliance leader 'Ttol-ggi' to gather characters from other servers to provide support, the disparity in troop quality proved too significant to overcome.

Conversely, the Notongsu Alliance dominated Pa'agrio. Although this server hosted the 'Chong-gun' Alliance—another pillar of The-K—the Notongsu Alliance held a clear numerical advantage due to reinforcements gathered from multiple servers. During the battles for Kent and Windwood, The-K failed to breach the outer gates, though they did manage to capture the Orc fortress just before the end of the siege, preventing a clean sweep.

Valakas was originally controlled by the 'Yeok-jeon' Alliance, which joined the Notongsu Alliance. However, the dynamic shifted dramatically just before the server transfer period ended, as a 'dissident' alliance affiliated with The-K infiltrated the server. Today's siege was a tightly contested battle, with the dissident alliance ultimately succeeding in a turnaround by capturing two castles.

Astaire is where the The-K Alliance focused all its strength, seeking revenge after being forced to surrender Kenlauhel to the Notongsu Alliance during the height of the server transfers. It is also the home base for the 'Free' team of the Notongsu Alliance's 'As-gorilla.' Despite it being a key server for the Notongsu Alliance, the The-K Alliance's invasion proved successful, resulting in the capture of all three castles.

Most of the fighting took place at Kent Castle. Although the Notongsu Alliance attempted to approach Windwood Castle in the very early stages, the The-K Alliance quickly unified to secure the castle and establish a defensive line, shifting the focus of the battle to Kent Castle.

The battle for Kent Castle saw an overwhelming number of participants—perhaps the largest in any siege to date—but it was not a balanced 5:5 fight. Given the inherent defensive advantages in a Castle Siege, the The-K Alliance, with its main force concentrated in Astaire, had no trouble intercepting enemies both inside and outside the walls.

The Notongsu Alliance deployed a tactic where the main forces, including Astaire's 'Free' team, attacked the gates, while Ttol-ggi, who had gathered late-arriving characters, spread his formation wide in the rear to prevent his allies from being surrounded. However, they were outmatched in both the quantity and quality of troops.

When no breakthrough appeared at Kent Castle, the Notongsu Alliance set its sights on Windwood Castle, but this also yielded little success. After returning to Kent Castle to continue the fight, the Notongsu Alliance shifted its target to the Orc fortress about 15 minutes before the end of the siege.

Because the Orc fortress offers fewer defensive advantages, it became the site of fierce final-minute exchanges. The Notongsu Alliance broke through the defensive line at the guardian tower to secure a 'Bound' status, only for the The-K Alliance to immediately reclaim it. With about four minutes left, the Notongsu Alliance captured the fortress and successfully walled off the outer gate, but the north gate was breached in the process. Ultimately, with about a minute remaining, The-K recaptured the Orc fortress, leaving all three castles in Astaire under their control.

Compared to the other two battleground servers, the power gap in Pa'agrio is relatively large. The balance was particularly disrupted when a large number of players from the 'Battle Master' guild transferred from the Deporoju server, the Notongsu Alliance's home base.

The The-K Alliance initially attempted to clear Windwood Castle before shifting its target to Kent Castle, continuing the field battle, but they were unable to breach the Notongsu Alliance's outer gate barricades.

As the battle dragged on in front of the gates, the Battle Master guild repeatedly flanked and intercepted them. Despite being at a disadvantage, the Chong-gun Alliance held their ground, but their morale gradually waned as the outer gates showed no signs of falling.

With about five minutes left, the The-K Alliance turned its attention to the Orc fortress. Fortunately, this strategy worked. The Notongsu Alliance followed them, leading to a skirmish inside the fortress, but the The-K Alliance ultimately defended their 'Bound' status, successfully preventing a clean sweep.

Valakas saw the most intense battle of the August 9th siege. The conflict escalated as a dissident alliance affiliated with The-K, composed of players from various servers, transferred in to challenge the Yeok-jeon (Notongsu) Alliance, which originally held the castle. The siege was a true back-and-forth, with the owner of Kent Castle changing repeatedly throughout the 60-minute duration, and neither side holding a significant advantage.

As the siege began, the The-K Alliance charged the main gate of Kent Castle, infiltrated the interior, and successfully captured the castle in just seven minutes. However, their joy was short-lived; three minutes later, the Yeok-jeon (Notongsu) Alliance destroyed the guardian tower and reclaimed the castle.

The chaotic melee continued. The Notongsu Alliance would capture the castle, only for the The-K Alliance to immediately reclaim it. The battle was so intense that the castle owner changed every 3 to 4 minutes on average, making the final outcome impossible to predict.

However, as the siege passed the 30-minute mark, the rate of ownership changes began to slow. While the fierce fighting continued, the The-K Alliance began to establish a more stable defensive formation through a series of successful handovers.

With five minutes left, both alliances were still clashing around the Kent Castle guardian tower, but it was the The-K Alliance that ultimately claimed the crown from the ruins of the tower in the final fight. As the outer gates were restored following the change in ownership, the Notongsu Alliance attempted to knock on the gates one last time before withdrawing with about a minute left. This resulted in the dissidents ending the long-standing rule of the Yeok-jeon Alliance in Valakas by capturing two castles.
