There's a piece of fluff I have been looking for for weeks now, it's driving me crazy.
It was one of those little snippets of fluff like OP's picture, don't remember from which book obviously.
It was about a gathering of young, enthusiastic people, who managed to overthrow a tyrannical government on their world, and managed to establish some normal, non-grimdark rule if I recall correctly. Then they got on a ship to go to Terra and try to convince the High Lords about their hippie beliefs, but 40k being 40k, something happened on the way and the ship that came out of Warp in Sol had obvious signs of hardcore Geller field malfuncion all over it.
I will give all my internets to whoever points me in the right direction.
