There are 50 Calcified Fragments to be found in Destiny: The Taken King.
This can only be obtained during King's Fall.
This fragment is available after you defeat Golgoroth. Head straight through the archway as normal.
Head through 2 doorways to the chamber with the glowing and spinning pillar in the middle of it. Once there, turn to the left.
Jump up onto the first ledge just inside the doorway. You will find the Calcified Fragment sitting against the wall, to the left, on the ledge.
Book of Sadness Entry
Oryx, my King, my friend. Kick back. Relax. Shrug off that armor, set down that blade. Roll your burdened shoulders and let down your guard. This is a place of life, a place of peace.
Out in the world we ask a simple, true question. A question like, can I kill you, can I rip your world apart? Tell me the truth. For if I don’t ask, someone will ask it of me.
And they call us evil. Evil! Evil means ‘socially maladaptive.’ We are adaptiveness itself.
Ah, Oryx, how do we explain it to them? The world is not built on the laws they love. Not on friendship, but on mutual interest. Not on peace, but on victory by any means. The universe is run by extinction, by extermination, by gamma-ray bursts burning up a thousand garden worlds, by howling singularities eating up infant suns. And if life is to live, if anything is to survive through the end of all things, it will live not by the smile but by the sword, not in a soft place but in a hard hell, not in the rotting bog of artificial paradise but in the cold hard self-verifying truth of that one ultimate arbiter, the only judge, the power that is its own metric and its own source—existence, at any cost. Strip away the lies and truces and delaying tactics they call ‘civilization’ and this is what remains, this beautiful shape.
The fate of everything is made like this, in the collision, the test of one praxis against another. This is how the world changes: one way meets a second way, and they discharge their weapons, they exchange their words and markets, they contest and in doing so they petition each other for the right to go on being something, instead of nothing. This is the universe figuring out what it should be in the end.
And it is majestic. Majestic. It is the only thing that can be true in and of itself.
And it is what I am.
