Ever After
Chapter 1
Immortality (Part 1):

Magnus sat in the chair thinking about everything that has happened to him in the past 200 years of his life. He had experienced love, regret, and a lot of reminiscing. It had been 100 years since all of his shadow hunter friends had left the Earth. They all died individually and in different ways, from sickness to an honorable death in battle against Jonathan Morgenstern. Only Magnus and the Day lighter are left, but Simon had left to a different place long ago to find peace for his lost loves death. Tessa had recently joined him in his New York apartment to finally meet her many great great's children, after many years of solitude in Europe thinking over the concept of her immortality.

Magnus was brought back to focus by the sudden knocking on his apartment door. Magnus slowly raised from his chair to answer the increasingly annoying knocking at the door, Magnus swung the door to see an all too familiar looking face at the door.

"Simon!" Magnus yelped in delight.

"Hey Magnus, how have you been?" Simon said as he made his way into the apartment.

"I'm okay; I have a new roommate that is sleeping so she should be waking up soon." Magnus replied with slight familiarity.

"Is she immortal?" Simon said as she started to look around the apartment.

"Yes she is immortal, older than you by at least 400 years. She is actually an ancestor of the Herondales."

"But how, I thought immortals couldn't have children?" Simon said skeptically.

"She is different, she-."

"Magnus are you telling my life story again?" A pale woman interrupted from the doorway.

"Of course Tessa, we both know your life is much more interesting than mine." Magnus replied sarcastically.

"Well than would you mind introducing us then." The woman motioned between her and Simon.

"Sure, Tessa this is Simon Lewis a vampire that can walk in the daylight due to an accident involving one of your great great-grandchildren. Simon this is Tessa Gray/Herondale, a warlock and shadow hunter child that is alive due to the Angel that was around her mother's neck when she was born. Also Jace's great-great-great grandmother." Tessa winced towards her introduction to Simon.

"Nice to meet you." Simon said after the awkward introductions.

"The pleasure is mine; I am guessing you know one of my descendants." Tessa replied politely.

"I knew one, and a little bit of your other family members."

"Oh I'm sorry, might I ask what happened."

"Well I knew Jace Herondale who me and my best friend Clary met at a club and then she discovered she was a shadow hunter like Jace and Alec and Isabelle Lightwood. Well we went on all of these chaotic adventures and that is how I became a daylight walking vampire. And umm… Jace died in battle from battling Jonathan Morgenstern, Clary's brother. After that Clary found out she was pregnant and she had twins which she named Max, another long story, and Lucie. After she had the twins and they grew up, Clary got engulfed in grief and got deathly sick and died in battle because she was too weak to fight back against her brother. After that her Lucie and Max married and had children, then their children married had children and onward." Simon finished teary-eyed as he thought about his dead best friend and what good times they had.

Tessa listened intently to the story, and gasped as she heard her daughter's name come up. She couldn't believe this all happened of her descendants. She had heard about the notorious Jonathan Morgenstern, but couldn't believe that Jace's wife was the famous Clarissa Fairchild-Morgenstern. Tessa could still remember the first time she had met Clary at that party in the City of Glass. She seemed the nicest and sweetest person; it was hard to believe that this sweet girl she met was the sister of the mean and crude Jonathan Morgenstern.

"Oh I'm sorry, my descendants seemed like they were really nice."

"Oh well not in the beginning he wasn't but he grew more loving as he got older. He had some incredible trust issues for a teenager and young adult." Simon replied wistfully.

"Simon, might I ask, why did you decide to come now after all of those years."

"Well I heard my eldest grandchild Grace died, and you know how I felt about her. So I am here to go to her funeral at the Institute. Would you like to come with me?"

"Sure, let me get dressed first, I haven't seen Clary's daughter Lucie's son Andrew in a long time. I know how Grace and Andrew were really close."

"Yeah, well let's go. Tessa, you can come too if you would like." Simon asked to Tessa.

"I'll be down in a second, if you wait." Tessa said as she started towards her bedroom door.

"We will wait, go ahead." Magnus replied as he ushered her towards her bedroom door.
