comic source (website) Explanation from a WH40k nerd friend:
Gulliman (the ultramarine primarch) is oft is basically king of admin and logistics
he is the spreadsheet lord
well the others were turning people into a floor made of human agony or being goth vampires he was looking at his 500 planets and doing the bookkeeping on why wheat production was down by 2.54% on one of them
one of the things that happened when he came back was the inquisiton went into a civil war based on calanders
because he wanted a consistant and uniform way to tell the dates of when things happened
yes that happened
you’re right, it is! I’ve edited to add the website source as well!
Amazing thanks highly efficient 🥰
