The betrayal referred to in Ezrelek's talk of the hundred-year script war is simply that Lilith's oracle demanded that they fight to the end.
Even if it means devastation, even if it costs two million vampire lives, they should be prepared for it!
Just as over time, the Empire and the Church started to express Miseria's oracle selectively.
Those Vampire Princes and Dukes also executed Lilith's oracle selectively.
The result of this execution was that the vampires chose to abandon the war to save their lives, and the Princes and Dukes were "compelled" to cease fighting.
The hundred-year script war ended, leaving both Lilith and Miseria dissatisfied, but both the Empire and the Royal Court were quite satisfied.
Evidently, despite the destruction wrought in mythology by these two deities, they clearly did not possess such immense power.
At least in the short term, they could not impose any effective punishment on the Empire or the Royal Court.
