The roars of WAAAGH's were met with screams of swarms of Tyranids that met in a symphony of the most primal of violence across the surface of Syvanus VI, a jungle death world that was sparsely populated by feudal humans that were often used in the recruitment of the Dark Angels legion.
The Monasteries the Dark Angels still guarded were the most heavily fortified of locations still on the planet, even as the rest of the world from pole to pole were engulfed in endless violence, even as the Dark Angels legion's naval forces fought in the void against the massive colony ships and the armada of makeshift Ork ships.
Within the Monastery, beyond the roars of the las cannons and artillery of the guardsmen assigned to this blasted conflict of endless war. A mountain of a man in green power armor leaned over a holographic display that showed the surrounding area around each standing monastery.
His wizened eye's took in the dozen of displays with inhuman calculation before he leaned back slightly and said. "Have the Astartes at sites fifteen A through F use their planted explosives in the nearby area. Then have the bulk of Astartes evacuated through the underground tunnels with what Guardsmen they can carry and guide in Op Deadly Dove."
A Tech Advents' Vox rang out in affirmation while Lion El Johnson leaned back with his expression pinching as he felt something... And he looked up towards the sky filled with Thunderhawks, Ork war craft and the flying Tyranid species.
And then another Tech Adapt spoke out with a screech. "Warp rupture recorded! It is the Ultramarine and Imperial Fist chapter reinforcements!"
Lion El Johnson, on the other hand, paused with his armored fists closing silently before he noted calmly. "They are early."
Then a crackle rang out as through the Vox channels that were connected through the Dark Angels' void ships that acted as the satellites to keep the Lion connected with his troops due to many other forms of communication being stopped.
And the Lion watched with a stern and cool expression as his 'younger brother' in a green holographic form stood before him. And as their eye's met through the connection, the Lion knew that this 'little' brother was indeed a Primarch crafted through his father's will.
However, just because he was a brother, just because he was made by the Emperor, this brother, who was made just recently. That didn't mean at all that he would be trusting him.
After all... At least half of his other brothers turned traitor.
"Little brother." He broke the silence first with his little brother blinking before bowing his head slightly and greeting in turn.
"Lion El Johnson. Eldest Brother, I hoped to meet you in a calmer situation but the heat of battle is the norm for the Imperium I suppose."
The Lion couldn't deny his words in truth but still he nodded and said bluntly. "Roubute has declared that you are to be blooded in this mess, so that is what will happen. However, I suggest you keep to the poles as that is where the fighting is lightest after all."
He gave a thoughtful nod before he said calmly. "I see, work from the poles to slowly push forward to the equator and wiping out all enemies on the way. You have a plan for Ork spores left behind?"
To which he just shook his head and said bluntly. "Better to leave a minor plague of feudal orks that will rise in a few months than allow the Orks and Tyranids to continue their arms race of slaughter."
There was a pause before the Lion's eye's tightened on his little brother's form as he knew his little brother was also an active Pysker and knew the signs of a Pysker who was listening to the tides of the Warp.
Finally, his little brother broke his silence to say thoughtfully. "I see, then I will work my ways toward you while the Imperial Fists will leave fortifications as we work towards the equator."
And with that, the line was cut with the Lion going back to ordering reinforcements and tactical retreats to parts of the many battlefields taking place across the planet while also ordering orbital strikes when the ships in space had time to actually shoot towards the surface.
But then a servitor's rough Vox speaker rang out in warning. "The reinforcing fleet has sent over five thousand drop pods into the atmosphere near the poles. No, registered Astartes drop ships detected."
Which left the Lion wondering what his little brother was up to. Clearly, he should be establishing a foothold in force on the surface of this important planet that was going to be built up as a shield world to break the teeth of the Orks and Tyranids upon.
