An Alternate Main Timeline refers to a version of the main timeline world where certain events or actions differ from what would have occurred in the standard timeline, yet it does not branch off into a fully separate alternate timeline or universe. This concept operates within the existing framework of the main timeline, meaning that the core structure of the timeline remains intact, but it experiences small shifts due to external interventions. These shifts do not lead to the creation of new timelines or universes; instead, they represent a subtle modification or variation within the original timeline itself.

These modifications are introduced by individuals, entities, or deities originating from realms beyond the affected universe, such as the Multiverse or Omniverse. Their actions subtly shift the timeline's trajectory while preserving its core structure and preventing the creation of new realities.

This phenomenon allows for the existence of variations in the timeline that do not fundamentally alter the fabric of its reality. While pivotal moments may play out differently—perhaps due to a traveler halting a significant war or an external deity influencing a leader's decision—the overarching flow of events remains largely intact. The timeline progresses as it originally would, albeit with altered nuances and outcomes shaped by the outsider's influence. These deviations, though impactful, are contained within the primary narrative of the timeline, ensuring that the world retains its continuity and ultimate direction.

Importantly, the concept of the Alternate Main Timeline distinguishes itself by emphasizing the limited scope of change. While it accommodates shifts in specific moments or decisions, these alterations do not result in long-term divergence or splintering of the timeline into independent universes. Instead, the variations are seamlessly integrated, representing a different interpretation of events within the same reality. This is made possible by the unique nature of the external agents—beings whose existence is not bound by the constraints of the timeline itself, enabling them to influence its course without disrupting its coherence.

Through this dynamic yet contained approach, the Alternate Main Timeline explores the possibility of temporary deviations that reflect the influence of otherworldly forces while ensuring that the primary reality remains intact. It creates a narrative space where the original timeline can evolve in response to external actions, offering a fresh perspective on familiar events without sacrificing its fundamental identity or coherence.

Salvatians exemplify a unique phenomenon, breaching into different worlds across the multiverse. Xavier Salvador, guided by his ideology rooted in Xavierism and Enlightened Ultraprogressivism, seeks to reshape universes that deviate from his vision of progress. His principles, which include anti-racism, anti-theocracy, opposition to the dichotomy of Light (Good) and Dark (Evil), and resistance to ideologies that serve personal gain, drive his actions. Willing to intervene directly or through military force, Xavier aims to alter the course of timelines and reshape worlds and universes according to his demands.

Here are breakdowns for more information about Alternate Main Timeline:

1. No Branching Into a Separate Timeline:

Key Concept: While events in the Alternate Main Timeline differ from the original timeline, the changes are not so drastic that they create a completely separate alternate timeline or universe. In essence, the world remains the same fundamentally, but certain actions or decisions lead to small-scale alterations.

Example: A key event (such as a battle, the rise of a leader, or a technological breakthrough) might unfold differently due to the intervention of an outsider, but the general progression of the world continues along the same path.

2. Influence of Outsiders from Other Realms:

Outsider Influence: The changes in the Alternate Main Timeline occur because of individuals, entities, or deities who exist outside of the original universe or timeline. These outsiders may be from a Multiverse or Omniverse, and their actions or decisions can influence the world without causing permanent, irreversible divergence.

Example: An external deity or being might alter a key decision made by a historical figure, subtly shifting the course of events, but the timeline itself doesn't "splinter" into a new, alternate reality; instead, it remains connected to the main timeline, albeit with minor changes.

3. Small-Scale Alterations:

Shifting Events or Outcomes: The alterations within the Alternate Main Timeline are usually temporary and situational, driven by the external intervention. These changes could involve specific individuals, battles, political decisions, or other impactful events that deviate from the original trajectory, but the overall outcome of the timeline will not drastically differ.

Example: In a story, an outsider deity may prevent the fall of a major city or delay a catastrophe, resulting in a different path forward, but the underlying flow of the timeline remains the same, and the world still moves towards the same ultimate end.

4. No Long-Term Divergence:

No Permanent Splitting: Unlike the traditional concept of alternate timelines, where an action causes an entire universe or reality to branch off and continue separately, the Alternate Main Timeline keeps everything within the same narrative continuity. It simply experiences slight deviations or variations that do not lead to fundamental changes in the nature of the universe.

Example: A traveler from the Omniverse might stop a war before it begins in a particular world. While this has an impact on that world, it doesn't create a permanent alternate reality; the timeline continues forward with new nuances, but there is no permanent split.

5. Limited to External Entities:

External Agents: The changes are caused by beings from outside the timeline, such as travelers, gods, or entities from different planes of existence, who have the ability to interact with the world but are not directly tied to the primary timeline's structure.

Example: A god from another dimension intervenes to prevent a tyrant from seizing control of a kingdom, but the timeline remains the same overall. The entity can make these changes only because they are outside of the timeline's regular flow.

6. A Dynamic but Contained Experience:

The Alternate Main Timeline is dynamic because it can evolve differently based on specific interventions, but the changes are contained within the overall framework of the universe. Unlike completely divergent timelines, these shifts don't create competing versions of reality. They're simply different interpretations or outcomes of the same underlying course of events.

Example: A character might have a different fate due to an outsider's influence, but they still fulfill their eventual role in the larger story, just in a slightly altered way.
