Seeing all these lore, maybe I should write one...
The Galaxy is as state, when an Outer Being, managed to goes into the realm as a series of mistakes, is intended to devour it, then the universe (Yeah, it's cheesy)
Mounting an effort against it, a Galatic Force is formed, but no weapon can stand against it. Everything that touch it is immediately consumed into the void emptier than void, and they're fighting a losing battle.
As a last ditch attempt, an experdition force, form by the Force's finest, is send on a suicide mission to the core of the Being, in hope of being able to strike as it weaknesses.
Many have been sacrificed, and consumed along the way, until finally, a single ships have reach the core...in which, they despair.
The core, where they expect to find it weaknesses, is a black hole of void, emptier than nothing, a screeching void that terrorize everything, and even just a look at it drain your very soul and mind.
Having to witness it, most of the crew despaired...except for one people. The captain of this fleet, not succumb to the madness of the void, see something beyond the void.
Having seen something, this very captain, bit the crewmember goodbye, then used an escape pot to jump directly into the hole, never to be seen again.
...No one know what happen in there, or what does the captain do, but after that, the Being itself do something very strange.
It began to eat itself.
Suddenly, the black void comeback unto itself, and the place that didn't managed to get eaten completely returned. Thing seems to returned like nothing happened, and soon enough, the Being, after consuming all of it part into a single point, disappear like such.
The Being disappeared, the Galaxy rejoiced, and the Captain is praised as the ultimate hero for his sacrificed.
But no one knew where he is, nor seen him ever again.
...The Captain, wake up on a field, in a new flesh.
Beside him, is a sword, adorn with a single blue gem.
What happen between them after that, is a story of another time, but this is how they met.
