The Grand Master of the 7th Chapter clashed blades with a man that looked like him, though the latter was carrying a sword that seemed to be made of some type of bone. Zane felt pressure from the shape-shifter, his strength overwhelming him. 

As Zane's blade neared his throat, he saw two knights approaching from behind the other creature. The two fired their smaller bolters into the creature's back, causing it to let out a scream that no human could make. 

As it lost focus, Zane pushed back with his blade and knocked the creature off balance before cutting off its head. 

"Thanks. How is the situation," Zane asked the pair

"We are holding out but sure how long we can do it," the female knight told him, hear armor covered in the purple blood of the creatures

"Our Sorcerers and Witches are doing their best to determine who is ally and foe but there are just too many of them. They keep sneaking behind our lines and hitting us from within and without at the same time," the 2nd knight said, trying to catch his breath

Rangda were unique shape-shifters that could take on the form of anyone. Most would take on the appearance of soldiers, Knights, War Hounds, and Grey Knights that had gotten separated from the main group and would use those chances to infiltrate their lines. 

It was only the Sorcerers and Witches who could see past their disguises, as they gave off a unique psychic signature. But the numbers of Psykers were very few compared to the millions of troops that they had deployed. It was impossible to keep watch over every spot. 

"Fuck! How is the fleet doing?"

"Not good from what I hear," the male knight told Zane. "That moon has heavy firepower and is tearing through our escorts. We are taking out those jellyfish ships, though."

"Hmm," Zane replied before looking off into the distance and seeing the constant warfare around them. They had been fighting for over the 10th day straight, not even getting a moment of peace. Zane had to switch out the Knights and Soldiers daily, letting them each take breaks in order to get some rest. The Astartes did better but they were running low on fumes.

The Rangda were a malicious species, sending out waves of their weaker members or slaves species and then hitting hard when their opponents let down their guards. With their strongest being a match for the Grey Knights, this was a losing battle. If no help came, they wouldn't be able to last for more than 5 or 6 more days before their ammo would run out and they were overwhelmed. 

Zane was about to give another order when he felt a presence in the air. It was one he had only felt once but it was one that reassured him and all the men and women that were fighting. 

Zane looked up to see an Astartes almost twice the size of a normal Astartes with two pairs of bright blue wings made of energy descending from the atmosphere. He floated in the air above the men who were fighting and looked at all the Rangda attacking them from all sides. 

Baldur was unleashing his full Primarch aura as well as his psychic might to boost the morale of his men and cause the Rangda to stop in fear. All eyes were on him as none could look away. 

"You have declared war on my sons and daughters, killing many of them. For that, there is only one fate that awaits your species. Genocide!"

Baldur lifted his spear into the sky, covering the tip in the same blue energy that appeared behind him as wings. Hundreds of thousands of lances made out of this energy appeared in the sky, nearly blotting it out. 

Baldur swiftly lowered his spear, sending down the lances against all the Rangda that were nearing his men. Countless lives were lost in an instant by this display of power, none being able to resist Baldur's might. 

Zane looked around the hill he was on and saw that the damage his Primarch had done, and felt warmth coming from his hearts. Both began to beat loudly in his chest and he was unable to resist the tears falling down from his eyes. 

'Our father... he came to us in our darkest time. As the 7th Grand Master of the Grey Knights, I feel ashamed for thinking that he would not arrive in our time of need,' Zane was glad that he had put his helmet back on because he could not afford to let his men see his tears. But even as the tears fell, there was nothing but a huge smile on his face.

It was not just Zane who had tears in his eyes. The other Grey Knights, War Hounds, and Knights that had come on this campaign also felt a deep sense of relief and renewed power. With Baldur's presence, they all felt as if they could battle for decades without break. 

"Come, my warriors. You shall live to fight another day," Baldur spoke directly into the minds of all those beneath him. Silver energy washed over each member of the 7th Fleet, dead or alive. One moment, they were on the planet. The next, they had each found themselves aboard one of the ships of the 1st Fleet. 

Zane stood on the bridge of the Invictus and looked out the window to see the remains of the 7th Fleet pulling back while the 1st Fleet provided fire support. He took off his helmet as he couldn't believe the sight.

Not only had the ground forces been rescued, but even the members of their fleet had aid as well. As much as he thought it was all a dream, he knew what he was seeing was reality.

He then turned to look at Baldur and Fulgrim who were both present and bowed toward the former. 

"Thank, Lord Primarch! You have saved us all!" Zane told his father

Baldur walked over and placed a hand on Zane's shoulder, causing the Grand Master to look up at him. 

"I was only able to save them because you commanded them so well. All those that live shall thank you as much as they shall thank me," Baldur told him, a slight warmth in his voice. "As for the dead, they shall thank us both as well when we avenge them. That is the duty of those who live."

"Yes, Lord Primarch. I shall fulfill my duty to my men," Zane swore, wanting to personally slay as many Rangda as he could.

With the 7th Fleet secured and their forces entering the Warp, the 1st Fleet was right behind them. Scans showed that reinforcements for the Rangda were approaching. Apparently, they had only been using the bare minimum against the 7th Fleet and were sending in the others to deal with Baldur.

Before any could arrive, Baldur and his fleet left. They were fine with losing this battle as the war was far from over.
