About Alphadia I & II

Alphadia I & II merges the first two epic fantasy RPGs into one continuous adventure. Updated graphics showcase attractive characters and a reimagined world, while new cross‑events link the stories of both titles.

Choices made in one game affect the other, and completing both under specific conditions reveals Alphadia II’s true ending. Players also gain access to a catalog of enemies and other bonus content, enriching the single‑player experience.

01 / THE GUIDE

Narrative Integration

The combined title weaves the plot of Alphadia I, set after the Energi War, with Alphadia II, which occurs two centuries later. The story follows the resurgence of the Schwarzschild Empire in I and the Energi Guild’s struggle against waning life energy in II.

Cross events bridge the two timelines, allowing actions in one game to influence the drama in the other. This linkage creates a cohesive saga that rewards players for experiencing both chapters.

  • Observe how decisions in the first half affect later scenarios; note any dialogue changes.
  • Track story milestones in a notebook to see cause‑and‑effect across titles.

02 / THE GUIDE

Energi System

Energi, the mystical life‑energy, drives both games. In Alphadia I it fuels conflict after the Energi War, while in Alphadia II the world’s dwindling Energi threatens existence, prompting the formation of the Energi Guild.

The system underpins the central conflict: the empire’s ambitions versus the guild’s preservation efforts. Players encounter this theme throughout the adventure.

  • Pay attention to narrative cues about Energi’s status; they hint at upcoming challenges.
  • Compare how Energi is portrayed in each era to understand its evolving role.
