A clarion followed shortly, sharp and loud enough to be heard by mortal and transhuman alike. The servants of Ultramar stopped what they were doing and stood to attention.

A towering figure clad in the famous Armour of Reason strode through the archway. On his left hand he wore the Hand of Dominion. Belted at his waist was the Gladius Incandor. The bearer of these weapons was taller by far than the Invictarus Suzerain guard escorting him. He exuded a power and purpose that halted the breath of mortals in their throats.

‘First Captain Andros! Second Captain Thiel! Are your companies ready?’ the giant called.

The two captains crossed the floor to meet their lord. Second Captain Thiel was helmetless in power armour heavy with honours, while First Captain Andros was completely enclosed in a hulking suit of Terminator battleplate. They saluted their father the Ultramarian way, one fist across their chests – the old symbol of unity.

‘My Lord Guilliman! Your veterans await your command,’ said Andros, his voice ringing from the voxmitter set below his helm.

‘We stand prepared, my primarch,’ said Aeonid Thiel. His voice, rich and soft, was unmoderated by machinery. It was not so very long after the Heresy, and Thiel was still young for a Space Marine, though his face was lined with cares.

Guilliman looked down upon his captains resolutely. The primarch overtopped even Andros in his massive Terminator armour. He was a living god, humanity’s might captured and moulded as flesh.

Thiel gazed back, seemingly unable to take his eyes from the face of his gene-sire. Thiel was a good warrior, tested in battle many times, unafraid to voice his mind and modest enough to hide the love he had for his lord, but it shone in his face like a light.

Such devotion they bear me, thought Guilliman, even as I fail them.

There were so few of his original Legion left alive, and their replacements were born of a different, less certain era. Thiel’s regard was tempered by long friendship, and he had never lost his rebellious streak. The younger Space Marines were another matter. Guilliman remembered when his warriors had been less reverent. They had been better times.

‘We depart immediately,’ he said, his voice uncompromising. ‘The traitor will not escape again. The warriors of six Chapters stand ready to aid us. We shall not fail. To your stations – prepare for mass teleport.’

‘My lord, we are prepared,’ said Andros carefully. ‘But the enemy will outnumber us greatly. I am concerned for our chances of success. What is the practical action should resistance prove overwhelming? It is Second Captain Thiel’s and my opinion that you should remain here. We shall occupy the enemy, while the Gauntlet of Power withdraws. We cannot–’

The Avenging Son cut Andros dead with a look.
