What exactly is the Black Spirit?

Summary You remain untainted by the Black Spirit NPC Knowledge and pose such a question.
You certainly have an extraordinary will and spirit.
All we know is that it's a primordial being,
residing in this land since time immemorial.
Observing you may shed light on unknown facets of its existence.
We look forward to more discoveries with your help.

Summary Ahh, your sudden departure certainly caused
a good bit of trouble for Edan, Orwen, and Yaz.
Edan was injured in his quest for the Origin of Earth,
and Orwen even encountered Belmorn.
Yet, it's through these trials we came together...
overcoming crises as one.

Summary Hmm? You find the sun's rising in the west peculiar?
There's a mystical quality about you, truly.
It's commendable for a scholar to question all phenomena,
but you're not a scholar, are you?
In this world, such is the natural order.
Unless, of course, the sky and the earth were to flip.

Summary Ah, you've been hunting ancient relics with the Black Spirit NPC Knowledge.
You're referring to the one that hangs from the ceiling, aren't you?
Its roots reach deep into an abyss far beyond our understanding.
What lies within that abyss remains a mystery to all.
Perhaps you, in time, may stand at the edge of that abyss.
But remember, never assume the abyss you see is all that there is.

Summary Who am I? Haha. Merely an old man,
wondering about how this world came to be and how it will eventually fade.
I seek out secrets hidden from the world,
and help hide those that should never see the light of day.
That's the essence of the Secret Guards and, by extension,
the Society of Equilibrium, a devoted order that protects secrets and maintains balance.
