'Brother Amadon's armour,' said Calgar, his voice rich with approval.
'Yes, my lord,' said Uriel, standing tall and with his shoulders back.
'It looks good on you,' nodded Calgar, reaching out to touch the brilliant white ''U'' on Uriel's shoulder guard. 'The last time I saw you armoured thus it was without heraldry, and you were leaving to an unknown destiny.'
'That was another life,' said Uriel. 'I see now why we have our code.'
'I know you do. Varro told me of your words within the Arcanium, and he is a good judge of the hearts of men. He says you have learned what you needed to learn.'
'I have,' agreed Uriel. 'Some lessons are learned the hard way.'
'Some men need to learn their lessons that way or they're not lessons at all.'
'And what lesson will this mission teach?' asked Uriel.
Calgar smiled and leaned in close so that only he could hear his words. 'It will teach those who watch from above that you are a true warrior of Ultramar.'
Uriel nodded, and looked over Calgar's shoulder towards the gallery where the Masters of the Chapter currently on Macragge had gathered to watch the 4th Company's departure. Here were the warriors who had once sat in judgement of him, but who now gathered to see him become one of them again.
Agemman of the veterans stood at the forefront of the masters, his noble features brimming with pride, and Uriel gave an almost imperceptible nod of respect to the Regent of Ultramar. This great warrior had spoken to Uriel the night before judgement was pronounced upon him. It had been Agemman who had convinced Uriel to accept his punishment for the good of the Chapter, and for that he would forever be in the First Captain's debt.
Beside Agemman were three of the battle captains of Macragge, Masters of the Ultramarines and guardians of the Eastern Fringe. Their names were legend, their deeds mighty and their honour boundless: Sicarius of the 2nd, Galenus of the 5th and Epathus of the 6th.
Of all the warriors here gathered, only Sicarius's eyes were as cold as a winter sky, his unflinching gaze never leaving Uriel as the 4th Company snapped to attention in unison, the sound like a hundred hammers slamming down.
'Lead with courage and honour, and you will win over your doubters,' said Calgar, following Uriel's gaze.
Uriel hammered his fist against the eagle upon his breastplate.
'Permission to depart Macragge, my lord,' he said.
'Permission granted, Captain Ventris,' replied Lord Macragge.
The roar of the Thunderhawks' engines surged in volume, and Uriel gratefully took the hand his Chapter Master offered him.
'It is fitting that this mission should be to Pavonis,' said Marneus Calgar.
'I remember,' said Uriel, 'my first mission as captain of the 4th Company.'
'Let us hope that this tour is not as eventful.'
'As the Emperor wills it,' said Uriel.
The base of the canyon was planed smooth, and Uriel recognised the application of Mechanicus scale meltas in the rippling, liquid texture of the rock. Lingering rain pooled in the darkness of Deep Canyon Six, and shadows from the high cliffs kept the temperature low. Patches of thick scrub, and wiry clumps of overgrown mountain gorse clung to the edges of the canyon. Tendrils of clammy fog drifted through the upper reaches of the forest of vox-masts that filled the canyon.
Uriel kept still and scanned the canyon. Nothing moved save streams of water pouring from cracks in the rock and the windblown undergrowth, yet Uriel had the acute feeling he was being watched.
Every one of his senses told him that this canyon was deserted, yet ones he could not name told him just as clearly that he and his warriors were not alone. He eased from the stepped gully that had brought them from the Thunderhawk's landing site, and the rest of his squad moved out with him. Two hundred metres to the north, he could see Lord Winterbourne's green frock-coat emerge from a narrow gap in the rocks, his storm-troopers forming a protective cordon around him. Uriel shook his head as he saw one of the storm-troopers holding the leads of the vorehounds. Taking unruly pets like that into a potential firefight was madness.
Uriel held his bolter out before him, scanning left and right, and allowing his auto-senses to gather information on his surroundings. The air had an electrical tang to it, which wasn't surprising, but it also had a strange, meaty aroma that the softly falling rain couldn't entirely mask.
'Combat formation,' ordered Uriel over the internal vox-network. 'Primus envelop right, Secundus left. Nice and slow. Harkus, you're with me.'
Proximity to the huge mast array was degrading communications, and his words were overlaid with squalls of biting static. To ensure there were no misunderstandings, Uriel placed his right fist in the centre of his chest and moved it in a slow outwards arc. He transferred his bolter and repeated the gesture with his left fist, slowly advancing towards the vox-masts.
The Space Marines spread out, Uriel and five warriors curving their route to the left as Learchus led the others along the contours of the canyon walls. Uriel advanced with Harkus at his side. The Techmarine had a bolt pistol drawn, and carried a cog-toothed axe, reminding Uriel that, despite his loyalty to Mars, Harkus was a warrior of the Ultramarines first and foremost. The armature limbs of his servo-harness were drawn in tight, soft spurts of gas venting from exhaust ports on his back.
'What can you make out?' asked Uriel, knowing Harkus would see the terrain in a very different way to the rest of the formation.
'The arrays are non-functional,' said Harkus, his voice flat and devoid of tone. A whirring lens apparatus clicked into place over the Techmarine's right eye. 'The residual flux readings tell me the generators are still functional, and…'
'And what?' said Uriel, holding up an open palm and pulling it down to his shoulder.
Instantly, his warriors halted and dropped to their knees with weapons trained outwards.
'I can see a number of attached devices that do not belong on this equipment,' said Harkus, scanning his head from side to side.
'What kind of devices?'
'Unknown, but they are not of Imperial manufacture.'
'Tau?'
'The energy patterns match previously encountered xenotech,' confirmed Harkus.
Uriel passed the word to Clausel and Winterbourne. 'Looks like the tau have definitely been here.'
'We have the northern approach covered,' said Winterbourne.
'In position on the ridge above,' reported Clausel. Uriel looked over to Learchus and nodded.
Both combat squads moved out, advancing carefully towards the array of vox-masts. The air snapped and fizzed with discharge, and Uriel's auto-senses were fluctuating wildly with the distortion and interference generated by the masts. An army of greenskins could be hidden within a hundred metres of him and he wouldn't know it. With a thought, he disengaged all but the most basic of his auto-senses, knowing that his instincts for danger would serve him better.
Step by step, they drew closer to the array. Uriel could see the devices that Harkus was talking about attached to the base of around fifty of the vox-masts and a few of the generators. Rectangular in shape, they were about the same size as a Space Marine backpack and formed from a hard, plastic-looking material. Etched into the surface was a circle that encompassed a smaller circle drawn from the larger circle's apex.
Uriel recognised it as a tau icon that represented one of their settled worlds, but he had no idea which one. 'What are they?' asked Uriel.
'I cannot answer that with certainty, Captain Ventris,' replied Harkus, the arms of his servo-harness unfolding and flexing like a collection of scorpion tails. 'Not without disassembly and study.'
