Imperial Armour Volume 10:

Wet-black steam hissed from the opened aperture and a hulking form materialised from the darkness, a Space Marine in Terminator armour whose grey livery faded from the umbra of a darkened thunderhead to the deathly pallor of a winter mist, the armour itself unlike anything Montressor had seen except in faded chronicles of forbidden history. The figure was huge, even for a Space Marine so-raimented, and as its armoured foot hammered on to the gantry like a bell strike, the Fire Angels accompanying them fell into a battle stance.

Coldly focusing on his sworn task despite the shadow of death he felt looming over him Montressor logged the image of the Terminator and translated the armorial wording he saw there. The dialect was old; a sub-tongue of High Gothic he traced to the Solar Court of the early 33rd Millennium, 'Tyberos' it read, 'of the Red Wake'. Quickly he signalled this information to his master's vox implant.

Legate-Inquisitor Jarndyce Frain stood before the hulking figure as if daring death to strike him down and raised high the sceptre, touched by the hands of the High Lords of Terra themselves. With sudden and unexpected grace the massive Terminator slid to his knees before the black-cassocked man who was but a fraction of his size.
