This story is heavily inspired by ptabs0101's brother - Remnant of a Rose. Go check that out along with its sequel; Remnant of an Iron Rose (Which got adopted). Some parts of this fic will be excerpts from that, so if you've read that story, you'll find some things familiar. I will clarify now:
I did not originally create this story idea in its entirety, this is a Fanfiction of a Fanfiction.
Backstory(!):
A century or few prior to the events of Destiny, Guardian Angela "Angie" was resurrected by a Ghost. She was the first of many things.
The first Eliskni to be risen. The first guardian of the Templar classification.
The first guardian to wield darkness alongside their light.
Their ghost, Lantern, was transformed into a Phantom to compensate this mixture of opposing yet similar powers. Angela became admired for her powers, and respected for her control, and not succumbing to the darkness within her. She became the Templar Vanguard of her small faction, partially by default but mainly to her many accomplishments. She also formed a relationship with Cayde-6, where they began dating before eventually marrying, Angela taking the name Angela 66.
Angela fought in the Battle of Twilight Gap alongside many other heroes, and in the aftermath gaining the admiration of Guardians and Fallen alike, her old House of Crosses reforming and naming her their Kell.
(This is where the crossover comes into play)
Not long after Summer Rose was resurrected as a Guardian, she met Cayde and subsequently Angela. Angela became a mother figure to Summer, soon adopting her as her surrogate daughter. Together they silenced the Black Garden's heart, slew Crota, defeated Skolas (with fury as he was the main perpetrator to the initial extinction of Angela's Fallen house), Stopped Oryx and deactivated SIVA (If I ever get to 'Remnant of an Iron Rose', it won't be called that or something similar, and, will have a completely different storyline). They also achieved feats such as raiding the Vault of Glass with Summer's fireteam; Nero, and sometimes with Angela's old fireteam; Excelsior (A notoriously flamboyant team of guardians).
And that is where we will start our tale of two worlds…
EDIT (9/06/2020):
How the actual F*CK Bungie?! How?! How did you make a DLC (Beyond Light) so close to this idea I've had for YEARS (Like since 2017/2018)? How? How?! HOW?!
So please just note I did not get the idea for Angela and Templars from that. Just to be clear.
Rest in Peace, ptabs0101's brother. You will be missed.
An alarm clock began blaring on the side of a bed in the Tower's living quarters. Two veteran guardians began to stir in their shared bed.
"Cayde… turn off the alarm…" a voice drawled.
"It's on your side pumpkin." a metallic voice yawned.
"…Oh yeah." A grey-skinned, three-fingered hand emerged from the covers and slapped the top of the clock, silencing it. Angie then sat up in the bed and stretched her four arms, a prolonged yawn escaping her spiky-toothed maw. Her glowing blue eyes were barely open, but she could still see Cayde's own metal face. Angie gave a small smile.
"What is it Cayde? You have that look on your face."
"Sweetie, I always have this look on my face. If you haven't noticed, but I am a robot and would take great offence if you hadn't." Cayde said, mock-hurt. Angie smiled wider and raised an eyebrow.
"Oh no, I noticed. Your face may stay the same but there's always something behind those eyes of yours." Angie leant over and kissed his cheek. she then swung herself out of the bed, followed by her armour materializing over her boxers and singlet.
"Heh, you got me." Cayde raised his hands, getting out of bed himself, his own armour also materializing, including his hood of course. "I was thinking you and I go and take a day off."
Angie raised her eyebrow again. "A day off?" she questioned suspiciously.
"Yeah, you and me. When's the last time we've done that?"
"Ten days ago. You, Summer and I went sparrow racing on Venus." Angie said as she made her way to the kitchen and ready a pot of coffee.
"Yeah, but summer was there. Mama and Papa bear can't get the real fun on if the little cub is around."
"You know I still don't get these hints Cayde. I have different anatomy to humans and don't even know how my own species 'Does It' as you say." Angie then poured four mugs of coffee. "You still need to talk to Summer about it, though."
"Ughhhhh." Cayde groaned, taking a coffee. "When will you stop asking me that?"
"When you do it." Angie smiled, picking up the other three mugs.
Cayde faltered. "Y'know that is actually a pretty good point. But wait!" Cayde hopped in front of Angie, hands outstretched.
"Yeah?" Angie asked, amused by Cayde's antics.
"What if I get Lux to do it?" Cayde then took a sip of his coffee. "This is lovely by the way."
"Thank you, and no. It should not be Lux's burden to talk to her innocent teammate about human procreation." Angie told him as the pair emerged into the tower courtyard. Cayde thought for a moment before speaking again.
"What about Ikora? I bet she'd be good at it." Cayde suggested
Angie chuckled. "It'd bet she'd also be good at lodging you in a wall. Which she will do if she had to explain it to Summer." Cayde drooped at that. The two Vanguards entered the tower control room to meet their fellow commanders.
"Ikora! Zavala! May I say you are both looking radiant." Cayde said to them, only for them to stare blankly back.
"Don't worry you two," Angie apologized as she brushed pass Cayde, "I brought coffee." Angie then handed a cup to each of them.
"Thank you, Angie, it has been a long night…" Zavala looked over at Cayde to watch him spill some coffee on his breastplate, "…and it appears to be an even longer day," He sighed. His attention was then called over by a Titan reporting in.
Ikora took a large sip of her coffee. "Thousands of years and humanity has still yet to come up with a better invention than this dark elixir." Ikora joked. Angie chuckled before taking a sip from her own coffee.
"So what have we got today?" Angie asked, leaning over Ikora's shoulder to look at the tablet she held.
"The Cabal seems to be mobilizing forces towards Mercury, they most likely are trying to take the planet from the Vex or trying to make the Vex lose focus on Mars."
"Tell me something I don't know."
"…Either way, according to reports, there is something there that they are taking great lengths to hide from us specifically. Not the Vex, but us. Which, as you may think, obviously does not sit well for me." Ikora informed Angie. "Most of our more seasoned Guardians are already dispatched, so we're going to have to send…" Ikora paused to sigh, "...Her."
Angie cocked her head. "Oh, come on, she's not that bad."
"Many guardians would beg to differ," Ikora debated.
"Look, if I go with her, will you stop complaining?"
Ikora paused in thought. "No. But I promise to complain less."
"I'll take it." Angie turned to where Cayde was trying to wipe more spilt coffee off the table. "Sundance!"
Cayde's ghost, Sundance, materialised in a flash of light. "Yes, Sugar?"
"Keep Cayde out of trouble."
"You got it, sweetheart."
And with that, Angie sent out to get her 'daughter', Summer Rose.
"Summer!" Angie rapped on the door to Summer's quarters in the guardian dormitories. "Summer wake up we have a mission!"
Angie then heard an alarm go off, followed by a gunshot, then followed by voices and finally the exclamation of "Mom?!" and hurried footsteps to the door. The door slid open to reveal a short female human hunter, with a white cloak and black hair that had red tips.
"Mom!" Summer threw her hands into the air.
"Hi Summer," Angie chuckled as she embraced her daughter. "You ready to go on a mission to see what the Cabal are doing on Mercury?"
"Yeah!" Summer cheered, armour materializing.
Two ships sped towards the Vex-converted planet of Mercury. At one point in time, the planet was covered in grasslands and trees with pink leaves, but during the collapse, the Vex undid this and turned it into a machine world.
It wasn't very out of character for the Cabal to try and conquer another world, let alone a planet-sized equivalent of a calculator. But as Ikora had told Angie, the Cabal were hiding something from the guardians, meaning whatever it was, it would be better in their hands than either the Cabal or Vex.
"I'm booooored!" Summer complained much to Angie's amusement. "Why did we have to take this mission again?"
"Because Summer," Angie said in her authoritative mother voice she had gotten very good at, "All other qualified Guardians are occupied with other tasks, Ikora was going to just send you but I came when she agreed to complain about it less."
"Sounds about right…" Drei, Summer's ghost, agreed. "Plus, both ships have stealth drives installed."
"Wait they do?" Summer asked, surprised by this fact, not remembering either Cloud Errant or Death to Kells having a stealth drive.
"Yes Summer, they do. We salvaged most of what we could from Eris' ship when it was destroyed. I had the stealth drive installed in Cloud Errant whilst I, acquired, a new one from the House of Devils." Angie explained. "Say what about the rest of my degenerate species, but they sure do make great stealth tech."
"Wait, when did you install it? I don't remember getting told about it." Summer asked.
"She told you about it whilst you were drooling over that new ship with all those guns," Drei replied.
"I was not drooling!" Summer exclaimed indignantly, "I was just appreciating its design!"
Angie snorted, bringing one of her free hands up to stifle a laugh.
"Mom!" Summer whined, embarrassed.
"There there Summer, I am not judging you for your… particularly passionate interests." Angie told her. Summer groaned, Angie, picturing the blush that would be across the white-cloaked hunter's face.
"It's not that bad…" Summer pouted.
"The fact that you spent more time than necessary to go over your weapons while talking to them like they were your children disproves your claim," Drei argued. Cue another groan.
"Oh, come on guys, lay off the girl," Angie's ghost, Lantern, spoke. "We all have our own interests so give her some slack."
"You're just saying that because you're an explosives-driven pyromaniac Lantern," Angie joshed.
"I will neither confirm nor deny if that statement is true or false." Lantern declared. They all laughed at this before turning their attention back to the approaching Mercury. A minute later they were flying into the small planet's upper atmosphere. It was at this time Angie glanced at her scanners and froze.
"Lantern, did you get the Death to Kells serviced like I asked?" Angie asked, comms line still open to Summer and Drei.
"Yup, full vault access, weapons and armour fabricator operational…"
"What about the scanners?" Angie interrupted.
"They're definitely working, why do you ask… oh." Lantern stopped when she checked the scanners for herself.
"Mom? What is it?" Summer asked as their ships descended closer towards the surface.
"My scanner is picking up a large mass of enemies," Angie answered.
"What kind?" Drei inquired.
"…All of them."
"Wha…"
"Fallen, Cabal, Vex, Hive, Taken, they're all here, right in the deadzone our scanners can't pick up from Earth," Lantern clarified, "And by the looks of those Cabal signal jammers, this is what they were hiding." She pointed out the satellite towers clearly of Cabal origin on the horizon.
"So, they were hiding a four-way battle from us? Why?" Drei asked, perplexed by the situation.
"Most likely because of what they're fighting over," Angie suggested. "If guardians got involved, they'd most surely be able to claim the prize. The only darkness sectors on Mercury are all in the Infinite Forrest, meaning that just a fireteam or two would be able to clear out the forces long enough for proper reinforcements to arrive."
"So, what do we do?" Summer asked. Angie put a hand to her chin in thought for a moment before deciding.
"Activate stealth Drive. We're going to see what the trophy is. Lantern, Drei, bypass the Cabal jammers as we go." Angie ordered. Summer and Drei complied, activating the stealth drive they got from Cayde and falling out of sight. Angie and Lantern activated their own drive, the outside of their ship becoming imperceptible by the naked eye and most scanners.
Approaching the site, signs of battle began appearing. Corpses of the four factions of darkness littered the ginger sands. Rounding a spire, there was a currently a skirmish between Fallen and hive. A Knight and Captain were engaged in an intense swordfight. They took quick note of the battle before descending into a tunnel that would lead them to where the site was. Even through the darkness, they saw flashes of Cabal Slug Throwers and Vex Torch Hammers.
"Approaching site now," Drei announced as they were partially blinded by the sudden change in light. When their vision adjusted, they gawked at what they saw.
The Fallen House of Devils Ketch, Heavy Cabal Troop Freighter, a Hive Warship and several major Vex gateways, all with minor ship and troops swarming around them. That alone was shocking to any Guardian, but what really took the cake was what they were all surrounding.
"What is that…?" Summer asked distractedly.
The structure that towered over the surrounding battlefields was like some kind of ancient pre-golden age Aztec temple, but made from dark stone and metal with power sources and mechanical parts sprouting all over it. At the peak of the temple was a large ring, easily three times the size of one of their ships, and bearing semblance to a Vex transfer gate, but not quite the same.
"From what I'm picking up, it's some kind of transfer gate…" Lantern answered. "But it isn't Vex in origin and is by far the largest one on record." Lantern went silent for a moment before speaking again. "By the Traveller… The gate is Human in origin and accepts the same activation keys as parts of Rasputin!"
"WHAT?!" the other three exclaimed.
"If I had to guess, this was most likely a Golden age invention to transport various things to far-off colonies. Probably made by Clovis Bray since it responds to Warmind codes."
"That's amazing…" Summer breathed in awe.
"Not so amazing assuming that if anyone else here captured it, and got it functioning, that they'd have access to what most likely would be a forgotten Golden Age colony," Lantern continued. "And if they were to reverse engineer it…"
"We need to report this to the rest of the Vanguard immediately," Angie concluded. "Lantern, Drei, how long until that last jammer is bypassed?"
"Thirty seco…" Drei began before cutting himself off, "Oh no! I'm picking up fluctuations in the power conduit!"
"Shit," Both Angie and Summer cursed simultaneously, knowing that this was what happened last time before the stealth drive fail whilst they were both crammed into Eris' ship. A few pulses of yellow and Cloud errant faded back into visibility.
The whole battlefield seemed to pause for a second before it resumed, a sizeable amount of the forces now dedicated to blasting Summer's ship out of the sky.
"Um, guys?" Lantern spoke up, "Remember how you said all the darkness zones were in the forest? Well, there's actually one here too..."
There was a slight pause between the guardians as they realized just how dire the situation they were in really was.
"Summer! evasive manoeuvres! They're going to try their best to not let us out of here alive!" Angie suddenly shouted over the comms before decloaking her own ship and diverting power to the shields and thrusters. Summer obeyed her mother and did the same, still cursing at 'Cayde's dumb stealth drive'.
Two Fallen Skiffs fell behind Cloud Errant and began bombarding it with plasma cannons. Angie Flanked the ships before tearing into them with her own cannons, sending them into a spiral towards the ground.
A nearby Tombship cruised by, launching off void blasts which caught the Guardians' ships, violently rocking them.
"Both Fallen and Cabal have signalled for reinforcements, Guardians," Drei informed.
"And those Cabal ground troops are looking for an opening to blast us with flak cannons," Lantern added. Angie gritted her spiked teeth in frustration.
Summer was doing her best to focus on the task at hand and not mentally berating Cayde for not properly making a stealth drive. But then, an epiphany hit her.
"Drei! Activate the transfer gate!" Summer pitched left and began heading to the gate.
"WHAT?! Are you crazy?!" Drei almost screamed. "Actually, don't answer that, but there is no way I…"
"Gate accessed, firing up the portal," Lantern interrupted.
Drei did the ghost equivalent of deadpanning, "I hate you all."
"Everybody hold on!" Angie yelled as the two ships sped for the brightly ignited transfer gate that shone a milky blue.
The battle around them once again paused as the portal illuminated the surrounding area. It resumed, this time with every force possible attempting to cripple Cloud Errant and Death to Kells. Summer took the brunt of the attack as she was in the lead, but Angie still took a considerable amount.
"Breaching Gate in 3…
2…
1…
0."
And then, darkness.
