what is the canon ending?
The "canon" endings are those that lead to Snowstorm, where Nick (MC) crosses the gate with one of the main girls from Sandstorm (Nora, Rion, or Maddie). When starting a game, Snowstorm asks which girl Nick went through the gate with. Another Sandstorm ending, which might also be considered canon, features Nora and Rion in a Mad Max-like setting, as it will serve as the foundation for the next game, Duststorm.
The idea of a "canon" storyline remains controversial. The developer doesn’t view it as legitimate and finds it confusing, preferring to let players decide which ending suits them best. Furthermore, entries in the Erastorm saga won’t necessarily be direct sequels or tightly connected; some may only share common themes or simply belong to the same universe.
Since the endings labeled as "canon" are highlighted in quotation marks, it’s uncertain whether any of the Snowstorm endings will truly qualify. This game might not have a direct sequel at all. Given that the developer rejects the term and that multiple endings can contradict each other, the concept remains open to interpretation.
