6000 years of in jokes

They would have developed their own language by that point

Mainly I just like the idea of the Big E actually like

Laughing uncontrollably

humanity's weird uncle (but in the good way, this time)

Dude is usually shown as super stoic and detached and kinda mysterious

Everyone else just like "the fuck is so funny"

And he's just like "ah you had to be there"

None of the pro march’s had ever seen Thr Emperor lose it before

Primarchs*

This is really charming

After just continually being buds for that long you’d be insufferable around each other

omnipotence should not preclude being able to just live life and have a laugh

those of you who claimed the god-emperor "lost it", you are being tried for heresy

the god-emperor was always in full control of "it" and chose to release his unflinching grip on "it" to live mas.

I like the galactic Waaagh'ometer in the background
