Wenoa Palentina (Weiss) was a rare exception to the rest of the royal children, she was the only one to be born directly into the ranks of her legion before the reunification of their Primarch, she was born aboard the emperor's battleship, inside of his laboratory using DNA from Omar Astarte and Fulgrim.
He did this primarily to help the crippled legion to 1 give it some hope of surviving and 2 allow them to have A source of gene seed to keep them going until their Primarch could be found.

She is also was a truly rare example as she was partly raised by the emperor himself mostly in the psychic arts as her particular potency was exceptionally strong even by comparison to Valkyrie of 6th legion.

She had and exceptionally high amount of psychic might the that could manifest in different element's, runed circles that could manifest for different purposes such as propelling herself forwards at high speed, which when combined with her use of mk3 iron armour, made her into a battering ram some terminators would have difficulty remaining standing after receiving the blow.

This training had left her with an ego to match which was tempered by the emperor also training her, instilling her with a great sense of temperance, who Wenoa would go onto quote him as saying "striving for perfection can in itself a goal one should achieve, but to chase it eternally is to doom oneself to excess and failure"

After her second year of education under the emperor and whilst he had made enough gene seed to keep the surviving astartes of the legion able to replace and very slowly rebuild their legion.

Once reunited with her legion she had become very close with all remaining 238 battle brother's but especially with Rylanor, "the ancient of Terra "as nicknamed by his brother's, she greatly enjoyed his love of history, remembering key events and traditions and different Rites.
As a result, she had appointed him as her royal praetorian and when the emperor tried to give her command of her legion for the time being, she refused and petitioned for him to become the master of the legion, as she had a lot of trust in his abilities.

The emperor had heeded her plea and Rylanor had been elevated to the rank of master of the legion much to his own surprise.
Both he and Wenoa were nicknamed the "1st born of Terra" whenever they took to the field in one another's company.

Her armour was a piece of supreme artifice, it was at its core Mk 3 iron armour with the mono visor of the MK 2.

Her helmet was almost all gilded gold, with a custom fitted hermetic seal built into it, to allow her flowing hair to be shown and not compromise her during void operations or in extreme environments.

Her face plate was a palatine Aquilla, the wings would come right up both sides of the helmet with each wing feather having a legion battle honour inscribed into it the heads of the Aquilla sat on the front most part of her forehead just above the visor

However, the further down the armour one looks they could see, despite it not being auramite is perfectly sculpted to fit her exactly, whilst still affording the protection of Artificer grade armour with an iron halo built into her neck guard.
Besides the daughter of samguinius, Wenoa was arguably one of the most beautiful of the royal family in or out of her armour.

Because of her legions size at the time, she couldn't take a company of her own to lead into battle but, she had fostered a strong sense of humility amongst them and would be quoted as saying
"Without discipline they can be no perfection, to gain discipline one must be humble to improve."

How little did she know this would be cause for a catastrophe...

the legion had risen to 500 astartes in number and she took up a full-sized legion squad and had named it the "Palentina blades" a unit of astartes with an incredible skill for swords in duelling and when in the field. due to them all possessing psychic powers due to being of her gene seed, her squad had gained a reputation for being extremely potent on the charge and once stuck into a melee it was incredibly hard to stop said squad from mauling whatever survived the initial charge.

and then things started to go wrong...

The legion alongside elements of the Luna Wolves with the Primarch and his son Jaune had been deployed to secure a Agri world that had called for aid to clear out a cabal of Eldar Xenos.
Wenoa had grown to absolutely abhor Xenos and even human mutants as she saw them as one of many things that had to go if humanity as to assume it's birth right.

Both she and Rylanor had insisted they deploy together with their legion and act as the spearhead for the assault however, Horus had cited major safety concerns for mostly Wenoa herself, but she could not be dissuaded from the course of action trusting in both hers and her legions skill to carry them through the action.

And with that the plan was set, Wenoa would lead the spear tip to the worlds primary Hive to clear a landing zone for the Luna Wolves to bring their heavier elements to bare on the Eldar and their human followers and spread out from there, a plan Horus had agreed to being the only Primarch present and having the seniority of command.

Wenoa is stood on the drop pod deck of the legion's current flagship the "champion of temperance" awaiting her Palentina blades to join her but she had come in advance of them to speak to Rylanor, master of the 3rd legion privately before the assault began.

She stands in her power armour and with her helmet off, to let her hair freely flow when She hears the foot falls of her most trusted astartes, and about turns on her heels to face the approaching Rylanor who held his helmet tucked under his right arm when she greets him.

"Ah, Rylanor, how are you feeling? Sanguine?" Her voice was one of angels to all those who heard it Rylanor especially and he responds with a smile on his smooth skinned face "I am sanguine my lady, I'm as sanguine for battle as any in the legions, this will be but child's play with the combined might of two of the most skilled legions in existence."

she smiles in response walking to greet him, her 5ft 9 hight dwarfed by him being the smallest of the royal children found or born thus far "well met, my champion." She pauses as a familiar warmth and heightened feeling washes through her again, a feeling that only seemed to be triggered when in his direct company.
She had felt it for quite some time at this point and had spent more than a few hours agonising over it trying to figure out if it was merely a warrior's bond or something more.

She had settled on something more...

Taking a deep breathe she resumes "I wanted to speak to you before we deployed together Rylanor"
The venerable astartes nods his head indicating for her to continue which she does "I have felt something about you for quite some time, I have spent exactly 3 months 4 hours and 23 seconds agonising over this feeling as to figure out what it is and I've reached a conclusion"

Rylanor being incredibly intelligent had figured out what she was about to say but wanted to hear it from her not wanting to rob her of it
"I have grown romantically attached to you Rylanor, understand it is highly unorthodox for such things to occur amongst just astartes never mind between astartes and demi Primarchs, I will would be understanding of you did not have these yourself, if you do, I would be honoured to take up an oath of moment with you."

Rylanor despite fully anticipating that, was still visibly shaken up a bit by this as he takes a tentative second to think his reply through "I would be honoured my lady, I myself have felt the same, it's been a true honour to train and lead beside you. you are a fine example of what humanity can be given the chance"

Wenoa beams at this and responds "your way with words never ceases to amaze me, your intelligence is part of the charm I adore, could you please kneel, I'm afraid I'm much to short even in my war plate to reach your pauldron"

Rylanor with a slight smile on his face kneels to allow her to reach his plate. Wenoa reaches behind her and pulls two purple dyed scrolls of paper, with the writing being written in silver thread, with both detailing the two's commitment to one another for now and as long as they live "I had made these not a week ago"

She pulls out a was stick and the wax seal stamped with the mark of the legion, and using the heat vent on Rylanor's plate melts the wax and attaches it to his right pauldron and he does the same, and now with this completed the operation can be conducted.
With the palentina blades and her new lover in her drop pod as well as the rest of the strike group they deploy to the surface.

Whilst the initial deployment had gone without a hitch a surprise attack by true Eldar had thrown everything into disarray, Rylanor and Wenoa had become separated and the Luna Wolves being led by both Horus and his son Jaune would were still en-route to the surface but, had run into severe interference.

Wenoa and six out of her remaining palentina blades, were fighting their way across a ruined stone plaza area with Wenoa having bisected a banshee and smashed her foot through its head, when she finally gets a clear enough signal to pick up Rylanor's beacon, and her heart sinks realising he's alone and seems to be pinned, looking at the direction she sees he's deep in the West of the city.

Voxxing to her master of signals nearby her she belts "GET THE SIGNAL TO THE LUNA WOLVES NOW!" She doesn't wait for a reply as she takes of followed by her body guard and several weekend legionary squads following her.

Using her psychic powers, she lunged forwards towards an Eldar loyalist human equipped in heavy plate armour, her power sword combined with her powers utterly ruins the man's breast plate and sending boiling hot goblets of his blood outwards along with ruined organs, kicking the spasming man of her sword, she focuses her eye lenses to try and get a direct sighting of Rylanor and she does, and her blood runs cold in her body.

He's surrounded by both four dead palentina blades and an odd terminator of the cataphractii pattern and dozens of this world's elite warriors and several dead Eldar with what appears to be an officer of their foul species battling to the death with a severely wounded Rylanor, who is desperately defending himself, the only thing not damaged on his armour is the oath of moment they took not twenty minutes prior...

She glows with a white light as several rune circles appear on the ruined ground and preparing her sword, aiming it for the Eldar's heart.

Launching herself forwards at a speed even her guardian's psychic as they are can't keep up with, the Eldar officer tries to back out of the way but Wenoa's sword bursts straight through its back and with the force of the impact it shatters every bone in its body and sends the crumbled corpse flying several dozen feet down the street.

With a sudden sense of panic, she rips her helmet off and locks it to her hip in time to catch Rylanor as he topples over drenched in blood and Eldar blood, as his wounds are going to be fatal, she screams "Rylanor...no no... GET ME A MEDICAE NOW!"
her psychic scream booms around the city as she hears over the vox unit in her helmet at her hip "deploying now..." the Luna Wolves finally got the signal to initiate their part of the plan through the interference.

Very quickly Jaune himself alongside his body guard the "Artemisian hounds" teleport strike in right next to them with medicaes, who immediately try to see to him and stop the bleeding, Jaune is able to peel the weeping Wenoa off the wounded astartes, as both his and her bodyguards conduct a thorough sweep of the area, before that though Wenoa of takes the oath of moment from Rylanor.

Jaune embraces his saddened cousin to try and console her saying "he'll be fine, I'm sure of it, come let's get you out of here, my company can help clear this city, you and your men have earned it" Wenoa reluctantly nods as the shock of the operation and potentially losing Rylanor hits her looking down at the spotless oath in her hand...

The operation had been a disaster, a full 50 percent of the surviving emperor's children had fallen in the operation, the Eldar had anticipated such a strike and had planned accordingly.

Wenoa was deeply ashamed of such a drastic failure having fallen into a deep depression, something made worse by the fact Rylanor, the master of the legion and her new lover head almost fallen in the process.

He had just barely survived long enough to be placed within the chassis of a contemptor pattern dreadnought, Horus had awarded Rylanor the title of the unyielding in honour of holding his own against so many.

A week later Wenoa finally brings herself to visit Rylanor deep within the armoury of the "champion of temperance"

she enters the chamber and dismisses the crew and in her royal non armoured attire, a deep rich purple uniform made in an ancient 15th century Terran style, with her power sword hanging of her right hip and her wide brimmed hat having 4 feathers wedged into it with 1 being taken from the emperor's own pet eagle, the 2nd was the khans own eagle, and the other two being form the wings of both Sanguinius and his daughter.

She takes the hat off, deactivating the Grav tech built into the inner ring and stands in front of the sleeping dreadnought and with a shaky voice says "Rylanor, can you hear me?"
"Yes..." Is his reply as his chassis helmet eyes light up green indicating he's awake "I apologise for my voice sounding off, I am still adjusting to this chassis..." He says trying to politely reassure her.

she smiles in response and takes out his oath of moment and stairs at it "I'm so sorry Rylanor, I risked us both and nearly got you killed... against Xenos no less... please forgive me..."
unexpectedly she feels a finger of his immense power fist on her shoulder as he replies "do not apologise, we both know the risk of what we do as demi Primarch and astartes, I would have rather I been the one in this position than you or even worse"

She leans her head against the large finger letting the cold ceramite cool her face "it still wounds me... the casualties alone do that but seeing you hurt hurts me as well, I have your oath... If you'll still have me, I would like to place it back on you, I will understand if you wish nothing more than to return to a professional relationship, the choice is yours"

Rylanor through great difficulty moves his power fist finger under her chin to face him "I would gladly still stand beside you as your companion, affix it to me"

After this her memory is a large blank...

When she next awakens, she's lying on a bed, a very comfortable one, but it was not her own bed...
She suddenly lurches upwards form the bed she sees she's in a large grey and white room, decorated in a mid-20th century Terran style and clearly extremely high-class luxury, turning her head to the window and sees a large near palace like courtyard and attached buildings which makes her extremely concerned as she turns back to the room as a hole and sees a family?

There was an old man, an old woman, a late teen woman and a very young boy no older than 4 at most, all of them dressed in whites, blues, and greys nothing looked like clothing she'd expect to see if she was still with her legion.
the old man presumably the farther speaks "your finally awake, are you able to speak?"

Blinking a few times Wenoa analysis the man and sees he's very clearly a business man of some merit when she answers "Wenoa Palentina... of the 3rd legion astartes and princes to the imperium of man... who are you all?" She asks her tone shaky and her body extremely week with her black carapace ports showing where her clearly borrowed clothes couldn't cover her.

The old man responds "I'm Jaques Schnee, this is my wife Willow, this is my daughter Winter and son Whitely" he says pointing them out in descending order of age.
Wenoa then asks "how did I get here? where's my armour? " She says panicking slightly as her psychic power is unstable causing icicles to form on the Windows glass and the wood of the bed.

The old man falling himself Jaques raises a reassuring hand to her saying "it's in the mansion armoury, our engineers are fix..." before he can finish Wenoa has her hands out to her side's, gathering psychic power in both her eyes glowing as a result " take me to it. NOW" her tone is deep and ethereal and echoes with the power only a grandchild of the emperor could muster greatly scaring the 4 of them, especially the boy.

they all very quickly take the demi Primarch to the armoury and dismiss the workers and show her damaged power armour with her power sword shattered and... "Rylanor..." Is all she says bolting over to a burned-out helmet of a Contemptor dreadnought and it's Rylanor's...
Turning around she faces the old man saying "how did i get here..." She's on the verge of tears seeing the obvious battle damage on it.

Jaques answers "we found you in our rose garden, you were on the verge of death with a disease coursing through you clutching that helmet for dear life... and covered in a disgusting green sludge, I'm sorry for whatever befell you, if you can trust us, we can help you, it's clear you've lost some of your memory."

Wenoa nods weeping as she feels numb all over like she's regenerating form something truly horrible "please... help me.. look I understand I must be what appears to be an alien to you especially with my interface ports, but please keep all of "this" a secret... whatever did this "she gestures at her damaged armour and resumes "finds out I'm here you are all at a very large risk."

Jaques thinks to himself "it'll be worth the risk but I have genuine royalty in the palm of my hands...this given time could prove to be their best ticket to riches and fame I've found since I've married Willow."

he then speaks aloud "then I would suggest a name change, what would you like to pick for yourself" he asks her but is answered with " I was born artificially as a result of a medical procedure form the DNA of my father and mother conducted by my grandfather, I am putting you all at risk just being here, I'll let you decide"

Jaques wasn't expecting that and answers "since my loving wife, Willow was the one that found you at 1st I'll let her decide"
Willow smiles warmly and looks at Wenoa's hair and says "Weiss, Weiss Schnee, it fits your beautiful hair"
