Quick Scoop

If Eru had kept journals after Mephisto was banished to the Void, they would probably read like a mix of confession, warning, and slow horror. The most interesting version is that the journals would show Eru not as a simple traitor, but as someone who believed he was preserving the only path he could see, even as the consequences kept getting worse.

What the journals might reveal

Eru’s entries would likely shift across three phases:

  1. Rationalization. Early pages would try to justify helping Mephisto, framing it as the lesser evil or a necessary bargain.
  2. Doubt. As the cost of Mephisto’s influence became clearer, the tone would turn fragmented, defensive, and uneasy.
  3. Collapse. The final entries would probably feel haunted, with Eru recognizing that the Void was not an ending so much as a delay.

That fits the broader lore idea that banishing Mephisto to the Void is more final than a normal defeat, but not necessarily permanent.

Likely journal themes

The journals would probably focus on a few recurring ideas:

  • Fear of chaos. Eru may have convinced himself that serving Mephisto prevented something even worse.
  • The illusion of control. He might describe believing he could guide events, only to realize he was being guided.
  • The cost of survival. The writing could show how desperation makes moral compromise feel practical.
  • Hatred as inheritance. Mephisto’s influence would likely appear not just as magic, but as a mindset that spreads through fear and grievance.

A journal like that would make Eru feel tragic rather than purely villainous.

Best story angle

The strongest version is probably not “Eru secretly became good,” but that his journals expose how self-deception works. He would not write, “I chose evil.” He would write, “I chose necessity,” “I chose order,” or “I chose the only path left.” That kind of voice makes the reveal land harder than a simple betrayal explanation. It also lines up with how fans describe Mephisto’s banishment: not an absolute end, but a dangerous pause that leaves room for return.

Fan-discussion angle

Forum-style discussion around this idea would likely split into a few camps:

  • Eru was always compromised.
  • Eru was manipulated from the start.
  • Eru genuinely believed he was protecting Sanctuary.
  • The journals would make him more sympathetic, but not absolve him.

“He got sent to where Lilith was banished to. So he can likely be summoned back the same way.”

That kind of reaction shows why the journal concept works so well: it turns cosmic lore into personal regret.

TL;DR

Eru’s journals would probably be a slow descent from justification to remorse, revealing that his real battle was not just with Mephisto, but with his own need to believe the sacrifice meant something. The best version would make him tragic, conflicted, and deeply human.
