The Race Against Time

Nefer warns the chess box containing Rerir will only hold for two days, creating urgent pressure on the team. During this preparation period:

Albedo and Durin’s research reveals Rerir’s body is now entirely composed of Abyssal energy, making him effectively immortal
Dori contacts the Dendro Archon, requesting aid and counsel against Rerir’s destructive powers
Varka develops a strategic battle plan for the confrontation

The Battle Inside the Chess Box

After two days, the group reconvenes on Hiisi Island to prepare for battle inside the chess box. Everyone joins forces to face Rerir, but midway through the fight, he separates the Traveler and Nefer from the others.

The confrontation takes a devastating turn when Nefer witnesses Rerir’s memories and mocks him for his inability to see truth, causing her eyes to start bleeding. Her provocation drives Rerir to unleash his full Abyssal power.

Dainsleif Reveals the Five Sinners’ Origins

The most significant lore revelation comes through Dainsleif’s confession. When Nefer asks about the events that led the Sinners to be tempted by the Abyss, Dainsleif explains that each was driven by their own desires and ambitions, which the Abyss exploited to cause Khaenri’ah’s downfall.

However, Rerir differed from the rest—he didn’t have a grand ambition at that time. One night, his brother Vedrfolnir was summoned by King Irmin, who gouged out his eyes and imprisoned him. Dainsleif gathered his friends to rescue him, but all, including Vedrfolnir, had turned against him by siding with the Abyss that night.

This backstory recontextualizes Rerir’s motivations entirely, transforming him from a simple villain into a tragic figure corrupted by betrayal and desperation.

Columbina’s Mysterious Power

The act concludes with an intriguing development: Columbina reveals she has gained strength from the Iridescent Moon’s power acquired earlier with Arlecchino’s help. This power boost raises questions about the Harbinger’s true role in Nod-Krai’s conflicts.

Frequently Asked Questions

Do I need to complete previous Archon Quests before playing Act IV?

Yes, you must finish Act III “A Nation That Doesn’t Exist” to unlock “An Elegy for Faded Moonlight.” The story builds directly on previous events, and skipping will leave you confused about character relationships and plot developments. The game provides a Quick Start function if you meet Adventure Rank requirements, but experiencing the full storyline is recommended.

Will there be more acts in the Song of the Welkin Moon storyline?

While Act IV provides major revelations, the ending leaves several mysteries unresolved, including Nefer’s conversation with Dainsleif and Columbina’s new powers. HoYoverse typically continues major Archon Quest storylines across multiple updates, so expect future acts to explore the aftermath of the Rerir confrontation and deeper Khaenri’ah secrets.
