A/N: This story is about my OC, Terra Grace. Some of the info is a little different than it is in the books, so don't get all hissy about it. A little bit of a back story for her:

Terra is Thalia's twin sister. She has been at Camp Half-Blood since she was 9. She came to the camp when Thalia did, brought by Grover with Annabeth and Luke. Her and Luke have been a couple since then. But, obviously, he died at the end of the Titan war. (I will probably do a story that centers around that, and some more that happen before the end of the PJO series). But now it's the world of TLH and she knows Jason is her brother and all that jazz. Terra has long black hair and the same blue eyes as her sister and the same fighting spirit though they are not alike with their personalities. Terra has a bracelet she wears on her right wrist. When she touches one of the charms a sword appears in her right hand. (It is supposed to be a match with Thalia's shield, but since there are two of them, they split the gifts from their father). It has been a year since Luke died and Terra has been having dreams that he is still alive. That's basically all you need to know… Oh, and she is 19 years old.

The sun was streaming through the windows of cabin one and making the whole bedroom way too bright for the two kids to stay asleep. Terra rolled over and pulled the blanket over her head.

"Someone tell Apollo to shut of the damn sun." She mumbled into her blanket. The boy on the other side of the room sat up and yawned, stretching is arms and scratching his blonde hair.

"Yeah, somehow I don't think he would go for that." Jason replied. Jason was Terra's brother, not just by their godly parent, Zeus…but by their mortal mother as well. They had only found this out a couple months ago but they were already used to sharing the cabin and they acted as though they had been living like this their whole lives. Jason and his two friends Piper and Leo were 4 years younger than Terra but since she was with them on their first ever mission to save Hera, they were all friends. Percy is still missing and Annabeth is currently out searching for him, so she has been spending a lot of time with the three new kids.

"You're probably right." Terra groaned and pulled herself out of bed. She loved the fact that Chiron got them beds rather than having the two of them sleep in sleeping bags on the floor forever. Terra hadn't cared so much before, but she decided since there were two of them living there now, with the occasional visit from Thalia, they needed some actual beds.

"So what are you up to today?" Jason asked as he pulled himself out of bed and headed behind a curtain on his side of the room. He grabbed an orange camp half-blood t-shirt and a pair of jeans before heading back there to get changed.

"Nico is visiting today. He has to talk to Chiron about something, though he won't tell me what."

"Ohhh. So I shouldn't expect you back tonight?" Jason laughed behind the curtain.

"Excuse me Mr.?" Terra exclaimed. But she blushed all the same. Jason came out from behind the curtain in the process of pulling his shirt over his head.

"Oh come on. Every time he visits you guys either stay out really late or you guys shadow travel somewhere for the night. You can't deny it." He winked at his sister while she gathered some clothes to wear.

"Fine…I admit it; we do spend a lot of time elsewhere when he visits. But it is because he doesn't visit often. He is always running errands for Hades. Or he is helping Annabeth search for Percy. The only reason I don't go with them to search is because Chiron put me in charge of helping you, Piper, and Leo with your new quests and what not. So until you figure out why your past is significant to this upcoming war, I am stuck with you." She made a disgusted face because disappearing behind the curtain on her own side of the room.

"Well fine then." Jason said sarcastically. "But hey I have a question."

"Shoot" She replied from behind the curtain.

"How come Chiron lets you and Nico go wherever you want but I have to stay at camp?"

Terra came out from behind the curtain wearing jeans and a black tank top. She grabbed a pair of strappy brown sandals and sat on her bed to put them on. "It's because you're important for this next war. We all know it. And besides, I am 19 years old, Jason. Asking me to stay here all the time would be dumb. I am an adult and can make my own decisions. Most demi-gods leave camp by age 18 and try to live a normal life. But since camp life is really all I have ever known, I don't care much for trying to live a normal life. All my friends are here, there is no point in leaving. Chiron knows this and he also knows that Nico and I can take care of ourselves. Nico turns 17 in a couple weeks anyway. To sum it all up: I have more experience, I am older, and Chiron trusts me more." She smiled at her brother who flipped her his middle finger. She laughed a little at his choice of responses.

"Well, I wanted to take Piper somewhere. But I guess I can't." He looked grumpy.

"This is your one month anniversary right?"

"Yeah. I wanted to do something special."

"I could give you some ideas about cool things you could do here? Or maybe I can talk Chiron into letting you and Piper take Blackjack and Eris to a beach somewhere?"

"Who are Blackjack and Eris?" He asked, looking puzzled.

"Blackjack is Percy's Pegasus. He saved Blackjack when Kronos' army captured him and was holding the Pegasus on the Princess Andromeda; his ship. And I got Eris from our father. She was sent as a gift when I was trapped by Kronos' army a couple years ago. Luke had been protecting me, keeping his soldiers from killing me, but he had to go somewhere, and long story short, they tried to feed me to a dragon. Eris is also a Pegasus. Both of them are black. You can tell them apart because mine, Eris, has a lightning bolt shaped white mark on her hindquarters."

"Her butt." Jason added.

"Yes, yes, her butt. And you should be able to speak to them."

"Wait…I can talk to a Pegasus?"

"Yeah, children of Zeus and Poseidon can talk to them because Poseidon made horses and Zeus added the wings." She explained.

"Weird…but awesome." He ran a comb through his short, spiky blonde hair. "So what is the likelihood that Chiron will let me take them?"

"Honestly? Slim. But I can try my best to convince him. Or you could pull a Percy and just take off from camp whenever you want. Keeping in mind, of course, that whenever Percy left he always got into near death experiences."

"Nice. Thanks for the bright note." He smiled at her, even though he was frustrated. He had survived on his own for years, or so he thought. "Why won't Chiron trust me?"

"Jason, please. It isn't that he doesn't trust you, per-say. He just doesn't want you to get hurt. You guys have only been at camp for about 2 and a half months. You can't expect to have all the experience you need to survive out there. Scratch that, you have experience that you can't remember getting. But Piper and Leo do not and it is their lives Chiron is worried about. The three of you are very important to this next war. Rachel has made the prophecy more than once now and he wants to make sure that the three of you remain safe."

"Which is why he put you in charge of keeping an eye on us."

"Only when you leave to go on missions."

"Well this won't be a mission; it will be one night to somewhere secluded."

"Think of it from his point of view though. I am not trying to put you down or make you feel bad, I am just playing the Hades Advocate here. During the last Titan war me, Percy, Annabeth, and Grover would be in very highly populated areas. The Hoover Dam for example. And we would be attacked. So he would be more worried if you said you were going alone." She sighed, still only halfway through putting on her first shoe. "Don't tell Chiron I told you this, but you should just go. Let Leo know where you are going however, in case something happens and we need to get to you. Alright?" He ran over and hugged his sister.

"You're the best."

"Don't tell Thalia you said that." She winked at him. He turned to head out of the cabin but she called out "the stables for the Pegasus are down past the Big House in the meadows!" And he was gone. "Be safe." She added to herself. She spent the next 15 minutes brushing her hair out so it didn't stand 3 feet off her head and put on some eyeliner and mascara. Hey, even demi-gods gotta look good times, right? After she was done she looked like her usually gorgeous self. She didn't have that other-worldly beauty that the children of Aphrodite had, or even Annabeth had. But there was something about her that made people stare. Maybe it was her long, dark hair that reaches halfway down her back, with natural waves that aren't quite curls. Or maybe it's the slightly tanned skin with the shockingly light blue eyes. Or perhaps it is the way she carries herself, knowing she is powerful but acting like she is no better than anyone else.

You see, as a daughter of Zeus, she has the power to manipulate the air the way Jason can. She hadn't known about this power, however, until she saw Jason do it. And then she only found out she had it when she fell of Festus during their first quest together. She had managed to catch herself right before she hit the ground. Jason was lucky, he was not a twin and therefore got both the ability to control air and summon lightning. Thalia and Terra, being twins, split almost everything; from the sword and shield Zeus had left with their mother, thinking there would only be one of them, to their powers: each of them getting one of the two powers that were unique to children of Zeus.

But the ability to propel yourself into a flip high enough to go over a giant when most demi-gods could barely flip over a Minotaur, was amazing in itself. So Terra wasn't too sad when she found out she couldn't control lightning when her other two siblings could. But hey, when they were falling off of a mountain or something…Terra was the lucky one. Being a child of one of the big three also meant that, along with these unique powers, came the common ones: faster, stronger, more agile, and better ADHD than most demi-gods. So her, her siblings, Nico, and Percy all had enhanced abilities. Not to say that made them particularly better than anyone else, but it did give them the upper hand.

Despite the fact that everyone knew this about them, the children of the big three that lived at camp half-blood never acted like they were better than anyone else. They assumed their roles as leaders but treated everyone equally. This is why they are so respected at the camp.

Terra looked herself over in the mirror. She ran a hand over tank top, smoothing it out. Her hand stopped about four inches above her belly button. She lifted her shirt a little so she could examine the scar that had been left when Kronos stabbed her over a year ago. Will Solace, from cabin 7, the Apollo cabin, had told her that the scar would never fully heal. She had been stabbed with a weapon that was made to kill humans as well as demi-gods and mythical monsters. Because of this, Terra would have a very unique wound and the scar would never go away, no matter how much Nectar or Ambrosia she consumed. Fortunately, she didn't mind the scar. It reminded her that she had saved the world, brought Luke back, and was able to prove to him one last time how much she loved him. Her fingers ran over the horizontal scar one more time before she pulled her shirt down and made her way out of the cabin.
