'I have crowed. I do crow. I am proud of what I did. When attacked, Magnus resorted to powers he should never have unleashed, and he deserved what he got for that alone. But things could have been different. Horus lied to me because they fear the power of the warp. He feared Magnus' sorcery. It is what the enemy are. It is what will beat them.'

Dorn sighed sadly, and looked down at his slate of plans. 'And that is Magnus talking.'

Sanguinius roused himself from his miserable introspection. 'Do you believe you were wrong at Nikaea, Leman?'

'Perhaps,' said Russ honestly. 'But I was not wrong to call for Magnus' sanction, nor was I wrong to call for the suppression of the Librarius as it was. Who knows where Magnus' path would have led had he been let alone? He might have won the war, but would we then have had another Horus to contend with, or maybe two? The Librarius could have proven as poisonous as the thrice-damned lodges.'

'The great proponent of the Nikaean edict, who kept his own sorcerers. You have many qualities, my brother,' said Dorn. 'I never thought to say hypocrisy was one.'

'Is it? The priests of my Legion and the Stormseers of Jaghatai's are different to the Librarians that were. Our warriors draw on an older tradition. A limited tradition. Magnus did not believe in limits. That was his error.'

'Similar traditions were outlawed by our father on every world,' said Dorn hotly.

'We have seen where His close-mouthedness on the matter of the warp has got us,' Russ scoffed.

Sanguinius made a silent gesture of agreement.

'Leman is right,' said the Khan. 'Our seers do not draw directly on the warp. Their gifts are mediated. We know what limits are.'

'Limits on power?' said Dorn. 'Power has no limits. Every morsel of power engenders more hunger. It is never satisfied. A man's soul needs to be a fortress.'

'Not limits of power, Rogal,' said Jaghatai. 'Our limits are those of human wisdom. You look for enlightenment in the wrong place. Wisdom is the limit that must be observed.'

'So now humility can tame the powers of the warp,' said Dorn. 'This is ridiculous.'

'Humility is one of the ways,' said Jaghatai. 'Our father is a psyker, so is Sanguinius, and Malcador.'

'The enemy fears the warp as much as they plunge themselves into it,' said Leman Russ. 'We must use it,' he held up his hands, 'safely, to help us win this war.'

'I still name you hypocrite. How can you stand it, Jaghatai? He opposed you at Nikaea.'

'That was then, this is now Dwelling on the past will solve nothing,' said the Khan. 'We must stand united.'
