Betrayal as infrastructure

The lodges, the second wave, “we’re on your side” at Calth. The Heresy works through the trust of the Great Crusade, not only through daemons: first a parallel hierarchy inside the Legions, then substituted orders, and only then the warp.

How to look in the atlas
  • The “Strategium” rail → “Event type”: compare “Politics · schism” and “Battle” over the span 3.5 – 7.2 — the betrayal advances by documents before it advances by fire.
  • Time slider: 4.2 (Davin) → 5.1 (Isstvan III) → 6.5 (the Drop Site) → 7.1 (Calth). Four frames of a single mechanism of trust.
  • Search: “Interex” — the earliest point where a lodge already works as a channel.
  • The dossiers of Erebus and Loken side by side: one builds the network, the other lives in it and does not see it.
