52	1	"Righteous Court I Saga"	Socialpoint		–
In the throne room of the Light Castle, Warmaster Thalassa confides in Empress Luthien and King Daeron her grief over her daughter, Thetys, who had demanded the throne of the Water Realm and vowed to leave if denied; after finally abandoning her mother, Thetys has now resurfaced. Thalassa recalls once leaving her daughter in charge while aiding the other Warmasters, only to return and find her ruling as a tyrant, forcing Thalassa to remove her from power. Their discussion is interrupted by the arrival of Pig-kin, a messenger from the Eastern Regions, who announces the impending marriage of Yaoguai Wangzhou to Mighty Thetys. As Thalassa departs to consult her court, Daeron and Luthien resolve that the time has come to summon their ancestor, Griffania Ironwings, by gathering her sacred relics. Daeron leads his forces to the Free Reigns, where Basthet warns him of Wangzhou’s alliance with Thetys to shore up his rule against rebellion, but nonetheless grants them Griffania’s golden scale and pledges her support should war follow. Their journey continues to the Peak of Conciliation, where Elvira Demonslayer gifts them an angel’s feather, but explains that the turquoise they require was given to Barbatos Rex during the treaty forged at the end of the Doomsday Era. When Barbatos Rex refuses to relinquish the turquoise from his scepter, they are forced to battle him and seize it. Returning to the Light Kingdom, King Daeron entrusts Bella Baal with the tale that Griffania was last seen by his own grandfather, and with the golden scale, angel’s feather, and turquoise now united, they perform the ritual that summons their great ancestor, Griffania Ironwings.
53	2	"Sea Old Guard I Saga"	Socialpoint		–
In the Water Realm, Frosilka confronts Warmaster Thalassa and her court, mocking them and urging surrender to Mighty Thetys before her imminent conquest. At her own council, Thalassa confirms her worst fears—that Thetys has destroyed the sacred reef of Corallia to transform herself, with the rest of its fragments gifted to Yaoguai Wangzhou to solidify their alliance. Resolute, Thalassa gathers the last pieces of Corallia from the royal vault to prepare for war against the Eastern Regions. Later, she confides in her ally King Daeron II, now transformed by Griffania Ironwings, who counsels her to summon her own ancestor for strength in this conflict. On her way back, she encounters Frosilka once more—now transformed into Rebel Frosilka—but brushes past her, desperately calling for Thetys to appear. Alone, Thalassa performs a ritual with her royal blood to summon her grandfather, Theton Tideborn, only for him to appear faint and translucent. Shocked, Theton tells her he has already been summoned by Mighty Thetys, who claimed her mother was dead, before fading away completely.
54	3	"Pure Gaia I Saga"	Socialpoint		–
While walking through the forest, Queen Zahra and Mother Talika catch sight of Griffania Ironwings soaring overhead, a sign of the growing unrest among the elements. Soon after, Pig-kin arrives with an invitation to the wedding of Yaoguai Wangzhou and Mighty Thetys, which Zahra interprets not as a courtesy but as a calculated display of strength aimed at the leaders of every faction. Seeking clarity, she visits the Righteous Court, where the rulers discuss the mounting tensions and resolve to let the Eastern Regions make the first move. Zahra, however, decides that if war is inevitable, Pure Gaia’s ancestor must be summoned. On her way back to the forest, Pig-kin and Raitosama confront her, accusing her of betraying neutrality by consorting with the Light Kingdom and treating it as an act of hostility. With Antlerian’s aid, Zahra narrowly fends off their Corallia-empowered soldiers. Later, she seeks counsel from Count Vlad in his castle, but he makes it clear that he will remain neutral, choosing to side with power as events unfold. Determined, Zahra turns to Anwrikah, the leader of the Wicked Gaia monsters, and the two acknowledge how crucial their cooperation has become in light of the threat. Together they conduct the ancient ritual, successfully summoning the ancestor of Pure Gaia—Robur Oldenshield.
55	4	"Righteous Court II Saga"	Socialpoint		–
As the Righteous Court prepares for council, Royal Magus interrupts with a vision: Yaoguai Wangzhou’s army, allied with the Barbarians, is attacking the Free Reigns. King Daeron II immediately dispatches troops to aid the besieged realm. On the battlefield, Jaakuna Hi warns Wangzhou that Daeron’s forces have arrived unexpectedly fast, though the Barbarians are managing to hold them back. Mighty Thetys offers her New Wave monsters to fight the Righteous Court directly, but Wangzhou refuses, ordering her contingent to remain guarding Basthet’s cell, and instead sends the newly allied Souls’ Lair monsters into the fray. Frustrated at being sidelined, Thetys vents her dissatisfaction to Rebel Frosilka, and the two decide to defy Wangzhou’s orders, leaving only Korol to watch the cell while they slip away to ambush Daeron’s forces. Meanwhile, King Daeron II and Sir Valgar cut through the dungeon’s defenses, only to find Basthet’s cell guarded by the lone Korol. Defeating him with ease, they free Basthet and gift her the Corallia bestowed by Warmaster Thalassa, transforming her into Eternal Basthet. Empowered, the trio return to the battlefield to turn the tide of the war.
56	5	"Sea Old Guard II Saga"	Socialpoint		–
Yaoguai Wangzhou and Mighty Thetys clash bitterly over her disobedience and Basthet’s escape, with Wangzhou coldly reminding her that he already possesses the Corallia and that, having severed ties with Thalassa, marriage to him is her only path to power. Alone afterward, Thetys summons Theton Tideborn, who scolds her for lying about her mother’s death but reluctantly agrees to aid her. Meanwhile, Queen Thalassa—having used Corallia to transform—rallies her forces and routs the last of Wangzhou’s army. Theton’s apparition appears before her again, explaining that he wishes to help both mother and daughter, and advising Thalassa to attend the wedding so she can speak with Thetys privately. Thalassa and King Daeron II travel to the Imperial Dojo to formally accept the invitation, where she offers to halt hostilities for her daughter’s sake. Wangzhou permits her to see Thetys but decrees she must first fight through the loyal New Wave rebels guarding her chamber. After battling her way inside, Thalassa finally meets with her daughter. Thetys admits she asked Theton to bring her mother, confesses her growing doubts after witnessing Wangzhou’s abuse of power, and reveals she has devised a plan to escape their bargain.
57	6	"Pure Gaia II Saga"	Socialpoint		–
At Count Vlad’s castle, where he has volunteered to officiate the wedding as a gesture to Yaoguai Wangzhou, Queen Thalassa arrives and takes her seat, joined by King Daeron II and Rebel Frosilka. Outside, Darmith Khan and Chieftain Alarorc act as guards for the ceremony, intercepting Queen Zahra, Anwrikah, and Robur Oldenshield, who are not there for the wedding but on their way east. Mid-ceremony, Pig-kin bursts in to announce that the Imperial Dojo is under attack—by Honor Dojo rebels and Pure Gaia. Later, Mighty Thetys regroups with Thalassa, Zahra, and Anwrikah, while Wangzhou and his advisors lock themselves in the Dojo’s rear chambers, believing Thetys is commanding her New Wave forces to hold off the assault. Thetys, however, reveals to the others that she knows the hiding place of the Golden Key to the Emperor’s Room, having explored every corner of the Dojo while Wangzhou excluded her from strategy meetings. Furious, Wangzhou accuses her of betrayal, but Queen Zahra interrupts to reveal that Kihaku has already entered the Emperor’s Room with the Golden Key. Enraged, Wangzhou attacks Thetys and Zahra. After the ensuing battle ends and the Fury Dojo monsters are driven out, Thalassa reconciles with her daughter, proposing that Thetys begin by leading her army and uniting the New Wave with the Sea Old Guard to gain experience before eventually inheriting the throne. Meanwhile, Kihaku, transformed into Tenno Kihaku by Thetys in apology for interfering with his rebellion, is restored to the leadership of the Eastern Regions, while Darmith and Alarorc begin to consider guiding the Barbarians into settling permanently and ending their nomadic ways.
