_____________________________________________________________________________________________

Time Skip

1 hours

The Battle is Over

The Thunder Warriors lose small Casualties, some are going to be a Dreadnoughts  others can still be recover and very small Dead 

Primarch Ronan, With Aquilla Commander Ronan, Arik Taranis, Dean and Nath along with the Praetorian Guards Walked towards the Imperial Command as they are talking among themselves

They stop Talking

They are still awe at him

"Who's in Charge here?" Said Primarch Ronan

"I'am" Said a Man in Power Armor a Mortal as he looked up at Primarch Ronan

"Ok, seriously i ask again who is In Charge" Said primarch Ronan again as the Mortal have Dared to say such to be a In charge

"I'am My Lord, inquisitor  Vorster Liesken" He said as he bow to the Great Primarch, the Space Wolves looked at the inquisitor with Disgust 

"Last time i Check there is no Mortal that can Command a Space Marine" Said Primarch Ronan

The Inquisitor looked unsure of what to say, Because the history have Said that the Thunder Warriors have been Lose to them as the Traitors have Claimed that they Destroyed the Thunder legion and their Primarch through a Very Powerful warp Storm that Destroy them as well their Realm and it is Well known that the Primarch of the Thunder Legion will take Offence of a Mortal who commands a Space Marine, without the Respect that are need to the Thunder Warriors to be Earned 

"I'll speak in his Behalf my Lord" Said Drstann

"I do not Recognize your Armor Warrior tell me what Legion are you?" Said Primarch Ronan

They looked to themselves "But i Recognize yours" Said Primarch Ronan as he looked to the Black Templars "Did Sigismund Finally Colored your Own specialize unit into Black?" He said

The Marshal Looked at him Unsure of how to answer to the Primarch

"But you i do not Recognize the Armor" Said Primarch Ronan as he looked to the Other Space Marines that are Different Color "But the Sons of Vulkan i Recognize them, the Salamander Legion and the Sons of Russ the Space Wolves Legion"

"And i do not See any More Space Marines here" Said Thunder Warrior Ronan as he looked "I only see small Numbers here, unless you have a High Casualties, but i do not see many Dead Either"

"My Lord, you may want to hear this" Said the Salamander Captain "The Legion has been Broken"

"What!" Said all the Thunder Warrior Primarch Ronan looks angry 

"Who Dares broke the Legion?" Said Primarch Ronan

"Our Father, Primarch Roboute Guilliman" Said the Novamarine Captain

They could certainly Saw Ronan eyes begun to shine bright gold with Blue Electricity

"That Fool he Managely did it?" Said Primarch "When i see i will Punch him to Death"

They all Back away in Fear to the Primarch even to the Novamarine Could not Defend their Father due to the Elder primarch's outburst 

"Where's your Father Ultramarine" Said Primarch Ronan, Since the Novamarine Said that Guilliman is their Father

"His on a Stasis my Lord" Said the Novamarine captain "He is Gravely Wounded by Fulgrim"

"What!" Said Primarch Ronan Shock "What about the others? Space Wolves Salamanders? Imperial Fist?!" He looked to them

"Our Father Gone Missing After the War of the Beast" Said The Salamander Captain

"Ours is Dead, during the 1st Black Crusade" Said the Black Templar Marchal

"Our Father Went to the Warp to Find some cure to the Emperor" Said the Space Wolves

"What do you Mean Cure? Cure for who?" Said Primarch Ronan

"To the Emperor, my Lord" Said the Space Wolves Wolf lord

"What do you Mean? What happened to my Father?" Said Primarch Ronan he hates his Father, but he must still ask this Question

"He is Mortally Wounded by Horus and it was sitting to the Golden Throne" Said Saint Elizabeth who joins the Conversation

"How long?" Said Ronan (Without Primarch Means that's the Thunder Warrior my self) "How long have we been Gone?"

"I believe 10,000 Years My Lord, this is M41,999 and it's closing Years" Said the Living Saint

That was shock to them that they have been gone for so long and some of the Loyalist Feel their Despair, Sadness, Anger, Hate and Rage Towards the Traitor Legion

"And Where is the Empress? Where is Me and My Brothers Mother?" Said Primarch Ronan in a Very Serious Question

"She has been wen't missing after the Emperor Sit to the Golden Throne my Lord" Said Elizabeth "We believe that she fall to her Despair and went missing since then" she added

Primarch Ronan Fall to his Kness in Sadness that their Benevolent Mother Went missing and no one knows what happened to her "Tell me Child what is your Organization?" Said Primarch Ronan as he looked to Elizabeth

"We are the Sisters of Battle my Lord, but we are Once called the Brides of the Emperor" Said Elizabeth

Then they Feel an Earthquake to the Ground and it was Powerful Indeed and they saw the skies Shaking as well

"Don't Dare you Call yourself a Bride to my Father Mutant" Said Primarch Ronan Dangerously as he looked to Elizabeth as she shrunk in Fear to the Primarch very Own Power and it was only releasing small amount of it "My Father will never looked to another Woman without our Very own Approval Do. You. UNDERSTAND!" he said very slowly at the Very Last Words

"Yes, my Lord i Apologies me and my Sisters will sure of it" Said Elizabeth as she Bow in Shame to Primarch Ronan

Primarch Ronan Nod to her as he Calmed Down "And Tell me  what about my Other Brothers? what is their Fate?" He ask

They Then Explain to him, that they are either Dead or missing Primarch Saddened that Sang is Dead Killed by Horus Himself

He felt himself Another Despair as he is the Only Loyalist Alive and while there is still some of his Traitor Brothers, Horus, Curze and alpherious are Dead, the Rest are still alive

Ronan Vowed that he will going to kill them

after some though of Revenge he heard a yelling

"Don't you Dare to do it again!" Snarled the Salamander Captain as he and his brothers along with the Space Wolves Aimed their weapons at the inquisitor

"It must be Done we will Never know of which one of them are possesed by Demons so we must Purge the Entire Survivors here!" Said the inquisitor as he and his Retinue along with the Grey knights aimed their Weapons as well

"Oi oi Don't you Dare Purge those Survivors and Civillians" Said Ronan in Anger as the  Thunder Warriors all Leveled their Weapons to the Retinue to the Inquisitor 

"What is the Meaning of this?" Said Primarch Ronan as he walked towards them his Voice Demand them

"Father, he Wish to Purge the Survivors with a Lamest Excuse that i have ever Heard, becuase they Just witness a Demon" Said Nath

Primarch Ronan Then Glared to the Inquisitor who is now cowering in Fear due to Primarch Ronan's power his aura is too Bright, even the Grey Knights are forced to Kneel, that have make the other Loyalist Shock as the Grey Knights being force to Kneel without any Effort at all

Primarch Ronan in Telekinesis Lift the  inquisitor up and Burn him inside out and last in 5 minutes and his body no longer remain not even ashes

"Is there more of you going to try and Purge more Innocent?" Said Primarch Ronan in his Booming Voice

"And you Grey Knights? i sense my Father's Blood Flow through your Vain, are you a Slaved to a Mortal, that you Even obey him to Purge the Innocent?" said Primarch Ronan 

The Grey Knights are still Kneeling and they could'n even Stand as they Struggle to Try it, they have already Read about Primarch Ronan's Power, his Power is Already Almost Equal to the Emperor and the Only Being that have ever Challenge the Emperor in Combat should he Ever wish it

And they have Never Though this kind of Power, This Power is Beyond for the pskyers even the Grey Knights Themselves

"You, know the Last Time a Space Marine Kill a Civillian without Mercy, is when the Heresy Happens  and they have forsaken their Oath of Protecting Humanity

So i will ask a Question are you a Loyalist Space Marines who's oaths is to Protect Humanity, or are you a Chaos Space Marines who will never hesitate to kill an Innocent People? So Which one are you Grey Knights?" Said Primarch Ronan

The Grand Master Use his willpower to looked at Primarch Ronan in the eyes

"I'am a Loyalist Space Marines and i will Defend Humanity as the Emperor have Created us to be that way" Said Drstann

"Good" Said Primarch Ronan as he smile

"My Lord we have News" Said one of the Thunder Warriors

"What is it Brother?" Said Dean

"It Appears Primarch Roboute Guilliman has been Resurrected and have already on his Way to Terra" Said the Thunder Warrior

"Then what are you waiting for? Let's go to Terra!" Said Primarch Ronan

"Permission Granted" Said Primarch Ronan

With it they Go to his Flagship
