Execute Morning

1) "The Code of the Perfect Warrior"

Stop bleeding and fight back!

I'll explain: this is a call to inspire the warriors, an appeal to their courage, and so on.
That is, a fairly unambiguous analogy.
2) "Footprint with a strange cross"

Black Heart Kabal

As I already said, this type of footwear is characteristic of inquisitors.
I'll explain: the black heart itself is not so important. The main thing is where it comes from. And it comes from Warhammer. I don't know the intricacies of this universe, but there is a deification of the Emperor and the Inquisition plays a rather important role. There even seem to be such troops.
3) "epic poem"
Here, it could be Warhammer again, or it could be Warcraft (which Morning wanted to attribute to me)

Due to your position as regional commander of the southern defense forces, Lord Terenas commands that you raise an outpost in the Hillsbrad foothills.
