Things I noticed in Horus Hersey book 1

[Montpup]

This is just a random list of things I found interesting, pictures and rules feel free to add

Page 57, in the picture one of the death guard has a funny looking helmet and another has a grey knight helmet

Terminators don't have the deep strike rule

That the Luna wolves earned their name from the pacification of Luna

The Luna wolves where the first to wear wolf pelts

Page 131 one of the death guard has a chaos style backpack

Page 203 one of the death guard has a different helmet again

The mechanicum land raider has a special rule "blessed autosimulacra" but I can't find the rule anyway in the book

The emperors children was reduced to 200 by the time they found Fulgrim

Dreadclaws are flyers

[Badtucker]

Dreadclaws have been flyers since always. ( although flyer rules were more complex back in the day for them)
