Understanding Penacony's Dual Ending System in Version 3.8

The Penacony arc concludes with two interconnected achievements revealing different narrative perspectives. Memories Are the Prelude to Dreams serves as the primary ending, while Oblivion Is the Curtain Call of Dreams unlocks through Dreamflux Reef exploration. Released December 16, 2026 (NA) and December 17, 2026 (EU/Asia), Version 3.8 implements these as part of The Rail Unto the Stars achievement series.

Unlike traditional branching narratives requiring multiple playthroughs, Penacony's system allows sequential completion. You'll first complete Memories, then access Oblivion through post-mission exploration. No permanently missable content exists.

What Are 'Oblivion Is the Curtain Call of Dreams' and 'Memories Are the Prelude to Dreams'?

Memories Are the Prelude to Dreams (80 Stellar Jade): Primary Finality Mission in Golden Hour requiring interactions with Jade, Robin, Aventurine, Dr. Ratio, Silver Wolf, The Dahlia, Black Swan, and Acheron. Culminates in fulfilling a promise with Firefly at The Radiant Feldspar.

Oblivion Is the Curtain Call of Dreams (10 Stellar Jade): Unlocks by investigating The Dahlia's secret base desk in Dreamflux Reef. This fragment of Remembrance provides alternative narrative context.

How Alternate Endings Differ from Standard Story Progression

Standard Trailblaze Missions follow linear progression. Penacony's ending system introduces conditional content triggered by specific post-story actions. Memories activates automatically upon meeting prerequisites, while Oblivion requires deliberate exploration.

Early reports suggested mutual exclusivity based on Firefly interaction choices at Radiant Feldspar. Verified gameplay confirms both achievements unlock sequentially: complete Memories first, then access Oblivion through Dreamflux Reef desk investigation. The leave Firefly versus stay and talk choice affects immediate dialogue but doesn't lock either achievement.

Why Both Endings Matter for Complete Lore Understanding

Memories focuses on closure with Penacony's major characters, providing emotional resolution. Conversations with Acheron explore identity and memory themes, while Aventurine and Dr. Ratio reveal strategic aftermath of the Dreamscape conflict.

Oblivion delivers The Dahlia's perspective through written fragments, contextualizing events from an observer's viewpoint. This adds depth to understanding Dreamflux Reef's role and Stellaron Hunters' broader objectives. Both endings provide comprehensive narrative coverage essential for lore completionists.

Prerequisites and Requirements Before Starting

Minimum Trailblaze Level and Story Mission Completion

Both endings require:

  • Trailblaze Level 34
  • Completion of Stranger in a Strange Land (Dreamflux Reef Trailblaze Mission)
  • Completion of A Thousand Bells at Dawn (prerequisite)

Stranger in a Strange Land rewards:

  • 30 Stellar Jade
  • 3 Lost Crystals
  • 100 Clock Credits
  • 42,000 Credits
  • 2 readable items: Now, Voyager and Had I Not Seen the Sun

Mission involves sequential farewells to Micah, Mikhail, and Acheron.

Critical Dialogue Choices in Stranger in a Strange Land

Four dialogue selections during Acheron's gravesite conversation for optimal narrative flow:

  1. Have we ever met before?
  2. What if... that wasn't an illusion?
  3. I think I might've seen... someone like you
  4. But some things will never change

These don't lock content but provide better narrative continuity into Memories. Incorrect selections slightly alter dialogue context but won't prevent achievement unlocks.

Recommended Preparation

No specific character builds or team compositions affect ending accessibility. Story battles scale to player progression. However, maintain sufficient Stellar Jade reserves for potential limited-time Penacony character reruns.

Complete Walkthrough: Unlocking 'Memories Are the Prelude to Dreams'

Step-by-Step Path to the First Ending

After completing Stranger in a Strange Land, Memories becomes available in Golden Hour. Begin by investigating a black cat on the couch next to The Dahlia's usual location.

Phase 1: Character Conversations

Speak with four character pairs (any order):

  • Jade and Robin: Post-Dreamscape political implications
  • Aventurine and Dr. Ratio: Strategic outcomes
  • Silver Wolf and The Dahlia: Stellaron Hunter perspectives
  • Black Swan and Acheron: Memory and identity themes

No dialogue choices affect achievement progression.

Phase 2: Firefly Promise Fulfillment

Navigate to Dream of Gnawing Oak to meet Firefly. Travel to The Radiant Feldspar. Investigate the note on the table to unlock achievement.

Rewards:

  • 80 Stellar Jade
  • 6 Refined Aether
  • 6 Lost Crystals
  • 300 Clock Credits
  • 80,000 Credits

Critical Decision Points and Dialogue Choices

The Radiant Feldspar interaction presents two options: staying to talk with the Stellaron Hunter or leaving Firefly. Verified testing confirms both options lead to the same achievement unlock, affecting only immediate dialogue variations.

  • Stay and talk: Extended conversation with additional Firefly character development
  • Leave: More abrupt conclusion but doesn't prevent Oblivion access

Both paths allow subsequent Dreamflux Reef exploration.

Missable Content Warning

No permanently missable content exists. You can revisit Golden Hour locations post-completion. However, specific dialogue lines vary based on conversation order—screenshot documentation valuable for lore enthusiasts.

How to Unlock 'Oblivion Is the Curtain Call of Dreams' Alternate Ending

Accessing the Divergent Story Branch

After completing Memories:

  1. Travel to Dreamflux Reef
  2. Navigate to The Dahlia's secret base
  3. Investigate the desk to discover a fragment of Remembrance

This immediately unlocks Oblivion achievement and awards 10 Stellar Jade. Content consists of readable text providing The Dahlia's perspective—supplementary lore rather than interactive gameplay.

Key Differences in Quest Objectives

Unlike Memories' character-focused conversations, Oblivion emphasizes environmental storytelling through written fragments. Desk investigation requires no combat or puzzle-solving, accessible immediately upon reaching the location.

The desk becomes interactable only after finishing the Firefly sequence at Radiant Feldspar. Players who completed Stranger in a Strange Land but skipped optional Dreamflux Reef exploration can return anytime.

Exclusive Lore Items and Readable Content

Readable items Now, Voyager and Had I Not Seen the Sun provide historical context for Penacony's development. The Dahlia's fragment offers Stellaron Hunter operational insights unavailable through standard mission dialogue.

These integrate into the Archive system for permanent review. Read immediately upon acquisition—they contain references to earlier story beats that benefit from fresh memory.

Achievement Series Contribution

Both achievements contribute to The Rail Unto the Stars series completion. Players pursuing 100% achievement rates must complete both endings to satisfy series requirements and unlock associated rewards.

Common Mistakes and How to Avoid Them

Misconception: Needing Multiple Account Saves

Early discussions suggested players needed separate save files to experience both endings. This stems from confusion about Radiant Feldspar choice mechanics. Verified gameplay confirms both achievements unlock sequentially on a single account without save manipulation.

The confusion originated from conflicting reports about mutual exclusivity. Testing confirmed the Dreamflux Reef desk investigation as the actual Oblivion trigger, independent of Firefly choices.

Skipping Dialogue That Triggers Alternate Routes

While no dialogue choices permanently lock content, skipping conversations during Memories reduces narrative coherence. Character pair conversations provide essential context for understanding Oblivion's written fragments.

Pro tip: Engage with all dialogue options. The game doesn't penalize extended conversation times, and no time-limited objectives exist.

Missing Time-Sensitive Exploration Objectives

No time-sensitive content exists within ending missions. You can complete Memories, engage in other activities for weeks, then return to Dreamflux Reef to unlock Oblivion. The desk investigation remains accessible indefinitely post-Memories completion.

However, Version 3.8's limited-time events may feature Penacony-themed content with actual time restrictions. Prioritize ending completion early in the version cycle.

Expert Tips from First-Hand Gameplay Testing

Optimal Order for Experiencing Both Endings

  1. Complete Stranger in a Strange Land immediately upon reaching Trailblaze Level 34
  2. Prioritize Memories Are the Prelude to Dreams next (80 Stellar Jade provides immediate value for limited-time banner pulls)
  3. Immediately travel to Dreamflux Reef to unlock Oblivion while narrative details remain fresh

The Dahlia's fragment contains references to recent conversations that carry greater impact when experienced consecutively.

Time Management: Complete Both Routes Efficiently

Total completion time: 2.5-4 hours depending on reading speed

  • Stranger in a Strange Land: 45-60 minutes
  • Memories Are the Prelude to Dreams: 90-120 minutes
  • Oblivion Is the Curtain Call of Dreams: 5-10 minutes

Reduce completion time by using quick navigation features. First-time players should allocate full time for optimal narrative experience.

Screenshot and Recording Recommendations

Document key dialogue exchanges during character pair conversations. Specific lines from Acheron and Black Swan contain references to broader Honkai universe lore. The Radiant Feldspar sequence features unique environmental details worth capturing.

Record The Dahlia's fragment text in Oblivion. Cross-reference with earlier Stellaron Hunter appearances to identify narrative connections.

Troubleshooting Guide for Stuck Players

What to Do If Alternate Ending Doesn't Trigger

If Oblivion achievement doesn't unlock after investigating the Dreamflux Reef desk:

  1. Verify Memories Are the Prelude to Dreams completion in achievement menu
  2. Confirm you investigated the table note at Radiant Feldspar (desk becomes interactable only after full Firefly sequence completion)
  3. Navigate to The Dahlia's secret base using map waypoint system (location consistent with earlier Penacony missions)

Verifying Mission Completion Status

Check Trailblaze Mission log to confirm Stranger in a Strange Land and Memories show Completed status. Partially completed missions prevent subsequent content from unlocking.

The achievement menu under The Rail Unto the Stars series displays both ending achievements. Grayed-out achievements indicate incomplete prerequisites.

Technical Issues and Support

Players experiencing bugs preventing achievement unlocks should document the issue with screenshots showing mission completion status and current location. Version 3.8's initial release may contain minor bugs addressed in subsequent patches.
