This is an actual passage from one of the books I cribbed online (I refuse to read any of their pro-fascist books)

It's gay as fuck

Santor watched as Ferrus Manus stood nearly naked before him, his servants washing his iron hard flesh and applying oils before scraping him clean with razor edged knives. [...]

‘I am your humble servant,’ said Santor.

Ferrus Manus waved away his armourers and moved to stand before Santor. Though Santor was tall for an Astartes and was clad in his full armour, the primarch still towered over him, his silver eyes shining and without pupils. Santor suppressed a shiver, for those eyes were like chips of napped flint, hard, unforgiving and sharp. The scent of lapping powder and oil was strong on his flesh, and Santor felt his soul open up beneath that gaze, his every weakness and imperfection laid bare.

‘You are much more than that to me, Santor,’ said Ferrus Manus, placing his hands on his equerry’s shoulder guards.
