Chapter 1: An Ordinary Day...

2030

It was a steaming hot day in New York City. Clarissa Herondale, Clary to her friends and husband, had just flopped onto a sofa inside the New York Institute. Her exhaustion wasn't caused just by the intense heat, but also due to trying to stop her two teenage children, William and Charlotte, from attempting to get a massive trebuchet into the Institute's weapons room. Of course, they were assisted by Jordan Lovelace, Will's parabatai. Clary laughed, remembering a similar scene from what seemed like a lifetime ago, with a particular blonde Herondale and his parabatai, the uncle to the assisting Lovelace. Clary nonchalantly ran her hand over the wedding rune on her other arm. Jace was in Idris at the Academy, giving a talk about the Dark War. Isabelle and Simon, Jordan's parents, were god-knows-where doing god-knows-what, whilst his sister, Cecily, was somewhere outside the Institute, but Clary could guess where she was. Clary's momentary serenity was broken by the front door of the Institute slamming. Clary walked into the the entrance hall and was met by Cecily Lovelace. She had her mother's hair and eyes, whilst she looked a lot like her father from a distance.

"What have your parents told you about slamming doors?" Scolded Clary. The teenage girl blushed slightly.

"Sorry, Aunt Clary." Apologised Cecily. Right at that moment, there was a momentously loud crash which seemingly came from the weapons room. Clary rolled her eyes.

"William Lucian Herondale! I told you 'do NOT touch that trebuchet'!" Bellowed Clary.

"It wasn't me!" Shouted Will from some unseen place.

"Downstairs, now! Bring your sister and parabatai." Ordered Clary, putting on her 'tough mum' persona. A few moments later, the teenage trio entered sheepishly. They looked a bit like the golden trio from the Harry Potter series: Will had inherited the Fairchild/Branwell colourings and hair, but inherited the Herondale personality. Charlotte was the opposite: a female doppelganger of Jace in appearance, but with Clary's creative flair and personality. She was mischievous though; she was a Herondale after all. Jordan completed the trio: an exact duplicate of his father, both in appearance and personality, even down to his need for glasses, though it was only for reading. Clary had offered to cure his sight problem with a rune, but Jordan had steadfastly refused.

"I told you not to mess about with that trebuchet." Scolded Clary. "Now, leave it alone. I will call your parents if you don't leave it, Jordan.

The threat hung in the air and the trio trudged away, Cecily following. As she walked away, Cecily left flecks of glitter on the floor, confirming Clary's suspicions: she had been visiting Alex, Magnus, Max, and Raphael. Cecily was Charlie's parabatai, but Charlie usually refused to accompany Cecily to Alec and Magnus' apartment, most likely due to her aversion to glitter. After dealing with the teenagers, Clary collapsed back onto a sofa and pondered about how she got to where she was.

2013

It was meant to be the happiest day of Clary's life. She was marrying the man she loved, Jace, who had proposed at the wedding of Isabelle, Clary's maid of honour, and Simon, Clary's parabatai. However, instead of the elation she was expecting, Clary felt incredibly nervous. She was standing, well, pacing in a small antechamber next to the large event hall, which was nestled deep in the corridors of the Institute. There was the faint sound of classical music. Jem, ex-Silent Brother, and temporary groomsman, had offered to play for the wedding after escorting Tessa in. His reasoning was that he wanted to, but couldn't, the last time he was at a Herondale's wedding (A fact that made his immortal wife smile in nostalgia and appreciation). Due to her nerves, Clary began to run through the details: Izzy was maid of honour, Alec was obviously the best man. Luke was taking on the responsibility of the father of the bride and suggenes. Alongside Izzy, the bridesmaids were Maia, Tessa, and Emma. The groomsmen for each were Simon, Jem, and Julian. The LA pair had come up, despite drama involving a lovesick warlock's dangerous spell, just for the wedding. Clary had an aversion to pairing them up, on the grounds they were parabatai, before realising the whole sleeping together thing was a mundane idea. Each of the bridesmaid/groomsmen pairs entered the hall, then it was Isabelle's turn. She exchanged an encouraging look with Clary; Isabelle knew about Clary's tension as she had married Simon the previous year. It was during the wedding reception that Jace had dropped onto one knee, in front of everyone, and proposed to Clary. Back to the present, and it was time for Clary and Luke to make their entrance. The hall was silent except for the quiet violin music. Clary immediately saw Jace, looking as handsome as ever, standing with Alec in a golden suit which made his hair seem to shimmer. His expression showed an emotion that Clary hadn't often seen from him: pure anxiety. Rather ironically, Jace's apparent anxiety relaxed Clary slightly. The redhead smiled at the blonde when they were level with each other. This made Jace smile and visibly sigh in relief. The ceremony passed quickly, with the exchange of material tokens and runes. Before she knew it, she and Jace were married and she was Clarissa Herondale. Well, Clarissa Fray Morgenstern Fairchild Wayland Morgenstern Lightwood Herondale. The wedding party then headed to one of the Institute's courtyards, where a large tent had been set up. The reception was an entertaining night. The roof of the tent was filled with what looked like stars, an illusion kindly provided by the joint effort Magnus and Tessa: Alec delivered a slightly drunken best man's speech, most likely as a bit of revenge for Jace's drunken outburst/speech at Isabelle's wedding. Emma and Julian brought congratulations from the Blackthorns remaining in L.A., saying that Livvy and Dru wanted to come but Diana had them 'really busy'. They also gifted the newlyweds with a photo album of the last time the Carstairs, Herondale, and Fairchild families had met, in the Victorian era. Below the pictures were the names of those pictured, in an elegant font. Pictured were William and Cecily Herondale, the latter becoming a Lightwood; Charlotte Fairchild Branwell, Clary's 'great-times-Raziel-knows' grandmother; there were pictures of Jem and Tessa, mostly with Will, who seemed to have black hair unlike Jace's blonde. The photo album even featured a Lovelace in the form of Jessamine. Clary and Jace gratefully thanked Julian and Emma. High ranking members of the Clave, including the Consul herself, congratulated the newlyweds. This made sense, as news of a high-ranking Shadowhunter missing the wedding of two heroes of the Dark War would run rampant in the Downworld and within the Shadowhunter community. The most memorable congratulations came from Clary's mum, who tearfully commented on how grown up Clary was, as well as warning Jace about the consequences of harming her daughter, much to Clary's chagrin and Luke's amusement.
"I won't harm her in any way. It's my duty to protect her now, after all." Responded Jace, jokingly serious. This seemed to satisfy Jocelyn and she and Luke walked away to allow others to give their congratulations and gifts. The night was filled with music, love, dancing, and pure glee. Clary couldn't believe that she and Jace were married, she couldn't believe that she was married. It did truly end up being the happiest day of Clary's life.

2030
Clary was broken out of her reverie by a familiar voice in the entrance hall. She got up and ran into the hall; standing there was her husband and the father to her children. Jace looked slightly jet-lagged, and had an overnight bag slung over one shoulder, When Clary quite noisily entered the entrance hall, Jace dropped the overnight bag and ran over to his wife, pulling her in for a warm hug and kiss. A few moments after their lips separating, the couple were 'attacked' by two figures; Charlie and Will were hugging their parents tightly, a rare family moment.
"I've missed you." Stated Clary to the taller blonde.
"I've only been gone two days." Joked Jace.
"Yeah, still." Commented Clary. "Will and Charlie can be a proper handful."
This resulted in shouts of dissent from the children who promptly let go of their parents. Clary and Jace laughed at Charlie and Will's indignation, After they separated, the couple noticed Charlie and Will heading towards the front door of the Institute.
"Where are you two going?" Queried Jace. "I just got home!"
"We promised grandma and grandad we'd visit today." Informed Charlie.
"Alright then. I guess I am home early." Reasoned Jace. Charlie and Will exited the Institute. Jocelyn and Luke lived in a small apartment a few blocks away from the Institute.
"They grow up so quick." Remarked Clary, jokingly. Jace smiled in response, and both reminisced about two days, one 16 years before and one a year and a half later.

It was late at night in the Institute. Screams could be heard from one of the many bedrooms. Despite the pain suppression runes, Clary was in intense and excruciating pain. A Silent Brother stood over her, making sure the redhead woman stayed alive. Clary was in such pain because she was bringing a new life into the world. Her labour had been going on for around five hours, but apparently the progress was swift. Jace and Izzy had been sent for more towels whilst Simon sat at Clary's bedside, giving his parabatai strength. The to-be father and adoptive aunt burst in at that moment. Seeing the obviously shocking scene, Jace took that moment to faint, Izzy catching the towels as the blonde collapsed. For a new mother, with her and Simon's daughter Cecily being born six months prior, and her being 3 months pregnant with their second, Isabelle was in shape and and as fast as she had ever been. Jocelyn and Luke were absent due to them being stuck in Idris. They were quickly trying to find some way back to New York, in a hope to see their grandchild. The excruciating pain continued for what seemed like forever to Clary. Jace was brought back to consciousness, and sat next to his wife for moral support. The labour took another five hours, then there was the sound of wailing. However, before Clary could see her baby, she passed out from sheer exhaustion.

Clary woke up about three hours later in the early daylight hours of the morning. Jace sat next to the bed, asleep, with a bundle of blankets in his arms.
"Hi." Greeted Clary groggily, waking Jace up.
"Hey." Responded Jace, equally groggily.
"Is that…?" Asked Clary, trailing off but gesturing to the bundle. Jace nodded and handed Clary the blanketed baby.
"Meet our son, Clary." Whispered Jace, trying not to wake the baby. As soon as Clary saw her son's face, she was filled with an intense love for the newborn. The new parents had already decided the name for the child, with options for both a son and a daughter. The son now cradled by Clary was William Lucian Herondale, named for Jace's Victorian ancestor, as well as other members of the Herondale family, and of course, Luke, Clary's stepfather and the closest person she ever had to a dad.
"Welcome to the world, William." Cooed Clary, before turning to Jace.
"Are my mum and Luke here yet?" Asked Clary to her husband.
"Yeah. They've met William. You've been out for three hours." Informed Jace.
"Three hours? I think I should get up again." Remarked Clary, going to stand.
"Oh no you're not." Retorted Jace "Brother Jeremiah said you have to rest at least six hours. You've just had a baby, Clary!"

2030
"You would not stay in that bed." Laughed Jace.
"You wouldn't let me get up!" Retorted Clary. Charlotte had made a slightly more dramatic entrance, with Clary requiring the Shadowhunter equivalent of a C-section. But soon enough, Charlotte Maryse Herondale joined the land of the living, and Will was an older brother. Back to the present, two things happened at the same moment: Simon and Izzy entered the room where Clary and Jace were standing, and Jace's phone began to ring. Jace took out his phone and saw it was Charlie ringing him. He stepped away from the trio to answer the call.
"You might want to talk to Jordan about disagreeing with Will at some point." Remarked Clary to Simon and Isabelle.
"Trebuchet?" Guessed Simon.
"Trebuchet." Replied Clary.
"I'm pretty sure Jordan was a fully willing participant. Alec told him about the time he and Jace tried." Informed Izzy. Clary went to say something else, but Jace interrupted by walking over. He looked incredibly worried, and the emotional link between Jace and Clary confirmed this for the redhead.
"What's happened?" Asked Clary worriedly.
"Will's disappeared on the way to Jocelyn and Luke's" Stated Jace, shocking the other three adults.
