Primarch return part 2

Horus decided to make a council of his 4 most trusted Luna Wolves he called the Mournival. Their job is to be his advisors.

The first member is Ezekyle Abbadon. He is angry, short tempered and violent.

The second is Garviel Loken. He's calm, dutiful and tends to be the voice of reason.

The third member is Tarik Torgaddon. He makes alot of jokes and is good at descalating tense situations.

The final member is Horus Aximand. He was given the name Horus at birth. Also he bares a striking resemblance to the Primarch. As such he was given the nick name Little Horus. He's a bit of a suck up to Horus, always fallowing orders no questions.

During a mission Horus and his Luna Wolves found a planet. There are machines around the planet sending messages but they couldn't understand the messages. They land on the planet and are attacked by giant spider like aliens. After losing horribly, they escape the planet.

As they leave the planet, they meet the Interex. Humans that evolved to have bat like ears that haven't rejoined the Imperium yet. They already knew about this planet. They named it **** and those machines are sending warnings so people won't land on the planet. Too bad the Luna Wolves technology is too primitive to make out these warings. Horus helped the Interex make new machines that can send less advanced signals so Imerium ships can read them.

Horus asked why don't they use their advanced technology to wipe out these super spider's? The Interex was apauled. The spiders where born on this planet. What right did they have to steal it and wipe them out? Horus apologized. Abbadon stormed off mad at Horus for apologizing. Horus sends Garviel to tell Ezekiel to come back once hes calmed down.

Horus talks with the Interex lerning about their technology and other human subspecies. In the original time line this is when Horus learns about Chaos and gets mad at his dad for hiding something this dangerous from him. In this timeline he's already fully aware of Chaos. If anything the Interex are horified to learn the human leader is half Chaos Goddess.

On a different mission Horus went to kill a Perpetual named Basilio Fo. He left Terra in horror of the Emperor of Mankind's plan for humanity. Over the years he had created monstrosities powerful enough to kill Space Marines. The Luna Wolves wiped out these monstrosities and Horus had a conversation with Basilio. By the end of the conversation Basilio asked Horus to kill him, not wanting to live in a universe where something as horrible as Primarch's and Astartes exist. Instead Basilio was impressioned on Terra for all eternity.

1 day Horus was douting his leadership skills and if he was worthy of being Warmaster. Sanguinius noticed this and cheared him up. After Horus felt better, Sanguinius had an idea. He should accept the name their mother gave his Leagon. He should call his Leagon the Son's of Horus. He should wear it like a badge of honor. To remind himself how confident the Empress is in him.

Horus agreed and really leaned into it. He not only changed the leagons name, he also changed the colour and logo. The white and black was replaced with a dark teal. The wolf and wet moon logo was replaced with an reptilian eye with a arrow going down it. They also replaced their mark 2 armor with more nimble mark 4 armor. Some of his leagon liked the rebranding, others prefered how they looked before. Either way the 16th has been changed forever.
