Fools.
It has become ever more rife amongst our number, and seventy-two warriors have succumbed to the flesh change since Magnus first spirited us away from Prospero.
Spirited… An old word, but an apt one perhaps, for we did not arrive on this desolate world by accident. This planet was waiting for us, prepared aeons ago by an intelligence greater than anyone, primarch or mortal, can possibly comprehend.
Magnus broods in his black tower, peering into the depths of the Great Ocean for validation, a sign that he was right to act as he did.
He will find nothing, for there is nothing to find.
His actions were never his own, for he forgot the first rule of the mysteries.
He let his ambition and hubris blind him to his flaws and the knowledge that there is always someone stronger and more powerful out there.
I will not make that mistake.
But we are still creatures of flesh and inclined to repeat our past mistakes, so I have been careful to surround myself with naysmiths to rein in my arrogance.
The bloodline of the Thousand Sons was born from the power that thrives all around us. We were given the chance to gather and pass on the knowledge of a hidden world, but we failed in that most golden of opportunities.
There are those among the remains of the Legion who do not believe the power of the Great Ocean can ever be mastered, that our accursed fate is clear evidence of that stark fact.
They are wrong.
This world is full of potential, but it is dangerous. Once I set foot on the path I believe will free us from our slow slide into degeneration there will be no leaving it. The Great Work I have begun will be the first step in proving how right we were, how loyal we were and how loyal we might yet be.
I promised to restore all that was lost when Prospero fell, and I intend to make good on that vow. This cabal will be the opening move in restoring the Thousand Sons to glory in the eyes of the Emperor.
I can feel them drawing near, the captains I must convince if I am to succeed.
Hathor Maat, I already know will join me, for he fears the ruin of his flesh more keenly than any. Sobek will follow my lead, as he has always done, but Amon?
Amon will resist, for he has served Magnus for longer than any of us can know.
He will be the key.
Win him over and this will work.
The Book of Magnus lies open before me, its pages filled with forbidden lore and knowledge from ancient, forgotten days. It holds the key to our salvation. In the labyrinthine collections of formulae, incantations and rites, I have found what I believe will be the beginnings of a mighty spell to undo all that has befallen us.
I call it the Rubric.
