Cheat Sheet
- Horus's Corruption on Davin -
Dive into the moment Warmaster Horus succumbed to Chaos on the moon of Davin, as chronicled in the Black Library Archives. Use the mnemonic "Blood on the Moon" to remember Horus's chalice ritual, which is a must-know for any horus heresy quiz or horus heresy legion quiz challenge.
- Dropsite Massacre on Isstvan V -
The betrayal at Isstvan V saw three loyalist legions ambushed by traitors, reshaping galactic power (source: Warhammer 40k Lexicanum). Recall "Five Zones, Five Deaths" to map each Drop Site and its doomed legion, a handy trick for Horus Heresy events quizzing.
- Siege of Terra -
Study the two-year Siege of Terra, the climactic defense of the Emperor's Palace against Horus's forces, outlined in official Imperium records. Visualize the walls of the Palace as concentric rings of defense - "Ring, Fall, Stand" - to lock down the final Horus Heresy trivia.
- Primarch Allegiances: Loyalist vs. Traitor -
Memorize the split of Primarchs (nine loyalists, nine traitors) using the phrase "Nine Two Sides" to instantly sort each legion's allegiance (source: Games Workshop Codex). Knowing which Primarch led which legion is essential for acing any Warhammer 40k Horus Heresy quiz.
- Chaos Gods' Influence -
Explore how Khorne, Tzeentch, Nurgle, and Slaanesh manipulated key events - summarized in the Chaos Compendium - to steer Horus's rebellion. The acronym "TSKN" (Tzeentch, Slaanesh, Khorne, Nurgle) helps cement which god fueled which turning point in Horus Heresy events quizzes.
