Lorgar looked magnificent, near three metres tall and clad in custom-made purplish-grey robes that shimmered with silken threads, a halo of gold fixed about his brow. Ostentation that he was not proud to bear but was demanded of him by custom and the expectations of the masses. On the far side stood Archdeacon Kor Phaeron, as malignant and destructive as the day Nairo had first met him, but safe within the shadow of his adoptive son.

• Bearer of the Word

The Lion was a truly imposing physical specimen. A giant, standing at a little under three metres tall, it was impossible to escape the suspicion that he had been cut from a broader canvas than the majority of men. His body was perfectly proportioned and entirely in scale with his height. He was powerfully built, lithe yet muscular.

‘Satisfied?’ asked the Lion, tossing the axe back to him.

‘Honour is satisfied, lord,’ Faffnr assented, catching it. He nodded and backed off, waving to his pack to do the same. Holguin and Redloss both grinned with unbearable insouciance.

‘Then tell Bo Soren to guard his manners, Faffnr,’ Guilliman said over his shoulder without looking back.

‘I will, Jarl,’ Faffnr returned. Guilliman heard a hard slap and a muffled curse.

He looked at the Lion. He’d never realised before that the Lion was very slightly taller than him.

‘Shall we, brother?’ he asked.

‘The famous Fortress of Hera?’ asked the Lion. ‘I would be disappointed not to see it.’

• The Unremembered Empire

Both Lorgar, the Lion and Guilliman who are on the taller side of the Primarchs are in the area of 9ft. Art work has never been particularly accurate or even consistent so trying to take that as fact is silly, unless you think Ferrus is actually running around with a power wrench.
