The order i always heard people explaining 40k was:
- An explanation of what the warp was before everything
- The old ones and what they did (webway, seeding the galaxy etc etc)
- What are the necrons and how did they discovered the c'tan (and what a c'tan is)
- War in heaven
- What are the eldar (and the orks) and what they did
- Then all the human history and recent events
I think the bot is fucking the USB stick, that's why it's malfunctioning
