Chapter 6: Ghosts of Gaia

Dick awoke as the sun shone through his bed hangings. He groaned as he sat up. His entire body was sore from the fight the previous night. He had bruises everywhere. Getting to his aching feet, Dick got dressed and traveled down to the Gryffindor common room. Sitting in front of the fireplace in a cushy armchair was Raven. Her head was resting on her shoulder, and her eyelids were drooping. Dick sat next to her. "Hey, Raven. Are you okay?"

Raven sighed and then responded, "I'm fine. Just tired I guess."

Dick searched the common room, confirming they were the only two in the room. He turned back to Raven and whispered, "Because of last night?"

"Yeah."

"Raven," Dick began, "when we first saw the daemon, you were confused. What was that about?"

Raven turned her tired eyes on Dick and explained, "I told you that was a Macabrel daemon, remember?" Dick nodded. "Macabrel daemons are stupid. They really have no thought. They go on instinct: attack, kill, feed. So it's odd that one would choose such a dangerous place to live. I mean, why live next to a dwelling of wizards, when it can live someplace safer. It had no reason to live there."

Dick spoke up, "That doesn't make any sense."

"I know. The thing about Macabrel daemons, though, is that they're fairly easy to control."

Dick looked confused. "What do you mean?"

Raven tried to explain, "With a few spells and a sacrifice someone could have a Macabrel daemon under his control, spreading carnage and mayhem in its wake."

Dick had caught on. "Someone like Voldemort?" Raven nodded. "But it didn't attack the school, only livestock. It was more of an annoyance than anything."

"That's what's bothering me. It must have had some other agenda." Raven looked at her hands in her lap.

Dick had an idea. "What if there are more? What if they're building an army in the Forbidden Forest? One was hard to kill, just imagine thousands!"

"No," Raven said. "To control an army, you would need extremely complex spells and at least five human sacrifices. Which isn't beneath Voldemort, I know, but it would be a waste of time, anyway." Dick looked confused. "Macabrel daemons are cannibals. They would attack each other as much as the wizards."

Dick frowned. "Well, then, maybe-" Dick was cut off by someone coming down the stairs. It was Ron.

"Hey, Dick!" Ron said waving. Dick waved back. Ignoring Raven, Ron said, "Want to go down to breakfast?"

Harry entered the common room as Dick agreed. Raven turned away from the friends and stared at the flames in the hearth. Harry noticed this. "Do you want to come down to breakfast with us?" Ron's jaw dropped at his friend's obvious disregard for 'the social order.'

Raven looked at Harry surprised. He smiled. "No thanks, I think I'm going to go back to bed a bit," she said. Raven stood and suppressed a grimace as pain soared through her aching body.

"Are you okay?" Ron asked as Dick helped Raven stand.

"Yeah. I just had a rough day yesterday." Raven gained her balance and Dick let go of her arm. Raven slowly walked to the stairs and started climbing to the girl's dormitory. Dick watched his friend with concern.

Ron headed for the portrait hole. "Let's go guys. Hermione's already down at breakfast, and you know how angry she gets if she thinks we slept in on a weekend." Harry agreed and the three boys left the common room together.

Hermione was reading a book when the boys arrived. As soon as she saw them, she closed her book and gestured for them to sit. The boys sat and started piling their plates with breakfast food. Hermione leaned in and whispered, "I have something to tell you." The boys leaned in as well so that the four person group was a huddle on the Gryffindor table. "Last night, at around two, I saw a hooded figure bring Raven to bed. She was completely out of it. I thought she was dead!"

Dick blushed and pulled back. "Are you serious?" asked Ron. "She was sore this morning, and she said she had a rough day yesterday."

Dick poked at his eggs with a fork. "Are you sure you weren't dreaming Hermione."

Hermione glared at Dick. "Oh course, I'm sure!" Dick sighed and continued to poke his eggs.

"What's wrong, Dick?" Harry asked.

Dick looked at his new friend. "Nothing." Standing he said, "I'm not that hungry. I'm going to… go somewhere." Dick then left the Great hall.

On Monday morning Gar was still sore, but well enough to complain. "Dude, this place is definitely not vegan friendly!" Gar had piled his plate with toast and was drinking pumpkin juice. His newfound Hufflepuff friends only laughed.

After breakfast Gar and the rest of the Hufflepuff fourth years headed to Defense Against the Dark Arts. Most of the students were happy about having Professor Lupin back, but some were still tentative of having a werewolf for a teacher even though they had already had three successful classes with him. Gar and his friends found seats in the middle of the classroom and waited for Professor Lupin to arrive.

Soon, Professor Lupin was at the front of the room and smiling at his students. "Today I have something very special planned," he said almost bubbling with anticipation. "I always have believed in 'hands-on' learning. I believe it is the best way to teach. I wanted to start us out slow, so today I'll have you face something you learned about last year: a boggart." Some of the students looked scared now. Lupin only smiled. "Don't worry. Boggarts show up in cupboards all the time. Every witch and wizard has had to face a boggart nesting in their home at least once. They're no big deal. Everyone leave your belongings except for your wand in the classroom and follow me."

Lupin led his class into the corridor and into a deserted classroom. An old trunk sat in the center of the classroom. Its dark cherry wood shone in the bright sun filtering through the layers of dust on the windows. "Now," said Professor Lupin coming to stand beside the trunk, "a boggart is in this trunk. I want everyone to imagine what they fear the most, and then image how you can make it funny. Each person will have a go." Lupin allowed his students time to ponder their fears.

Gar knew right away what the boggart would turn into for him: brain-eating zombies. Gar decided to make it funny by having it eat its own brain. Gar silently laughed at his hilarious yet gruesome idea.

Lupin addressed his class again, "Okay, class! Who wants to go first?" A girl with light blonde hair stepped forward. "Very brave, Miss Hawkins." The girl gulped. "On the count of three, I'll open the trunk." The girl slowly nodded. "One," Lupin put his hand on the trunk, "two," Lupin gripped the red wooden handle, "three," he pulled the trunk open in one quick motion.

The girl gasped as a large, dark purple dragon emerged from the trunk. The girl planted her feet, pointed her wand, and yelled, "Riddikulus," just as the dragon was about to breathe fire. When the dragon blew out, little droplets of water spewed from its mouth. The class roared into laughter at the look of a confused dragon.

Lupin took command. "Paul, go!"

A small boy with dark skin and black eyes approached the dragon. In an instant, the dragon was a large barking dog. "Riddikulus!" The dog's mouth disappeared.

"Sarah, go!"

A girl stepped forward and the mouthless dog turned into a menacing vampire. "Riddikulus!" The vampire's teeth fell out much like dentures.

"Garfield, go!"

"Brain-eating zombies here I come!" Gar yelled as he ran to face the boggart. To his surprise though, the boggart didn't turn into a zombie. Instead a girl with bright blue eyes and long blonde hair stood before him. Her clothes were odd. It looked as though she was wearing grey, skin tight armor. On her chest there was a large "S" symbol.

"T-Terra?" Gar stammered. He dropped his wand. The girl's eyes glowed bright gold and she raised a fist. The fist swiftly turned to stone. In an instant, the girl's stone fist made contact with Gar's face. He was thrown across the room and landed in a heap on the floor. "Terra!" he yelled as the rest of the girl's body quickly tuned to stone.

Lupin ran forward and faced the boggart which quickly turned into a floating orb that the entire class realized was a full moon. "Riddikulus," Lupin yelled, and the moon turned into a cockroach scurrying across the floor. Lupin scooped up the cockroach and threw it into the trunk. Slamming the lid closed, Lupin turned to look at Gar, but Gar was gone. Lupin's attention turned to the closing door of the classroom.

Around the corner in the hall parallel to the classroom, Gar sat on the floor leaning against the wall. Tears streamed from his bright green eyes, mixing with the blood from his broken nose. His greatest fear wasn't zombies. It was having Terra and losing her again. Gar closed his eyes pushing out his tears as a head peered around the corner. Lupin sat next to Gar and leaned against the wall too.

"Can I fix your nose?" he asked. Gar opened his watery eyes and turned to Lupin. Slowly he nodded. Lupin raised his wand and aimed it at Gar's face. He slightly flicked his wand, and Gar could feel a warm sensation as his nose healed. Lupin tucked his wand away. "Who was that?" he asked in a soft voice.

Gar turned his head away. "I don't want to talk about it."

Lupin sighed and stood. "Come on," he said, "let's go to my office." Lupin extended his hand. Gar looked at his hand first, then took it, and allowed himself to be pulled up. Lupin led Gar past the now empty classroom to his office. A small fire was roaring in the hearth, and many books were scattered over the entire room. Removing some books from a chair, Lupin indicated that Gar was to sit. Gar sat in the plushy chair and Lupin sat across from him.

"Sometimes," Lupin began, "it's easier to talk about it." His voice was comforting, and Gar looked into his teacher's tired eyes.

Taking a deep breath, Gar said, "She was my girlfriend. She died about two years ago."

"How did she die?" Lupin asked genuinely concerned.

"She became stone." Tears cascaded from Gar's eyes once again as he thought of this.

Lupin nodded, now understanding what happened with the boggart. "How did that happen?" Lupin was now curious as to how a person became stone.

Gar sniffed and blinked back more tears. "She died saving us."

"Us?"

"The Titans."

Lupin was now completely lost. "What are talking about?"

Now Gar looked confused. As he wiped the tears from his eyes, he said, "Dumbledore didn't tell you?"

"Tell me what?"

Gar leaned back in the plump chair and began to talk, "Dick Grayson, Kori Anders, Victor Stone, Raven Roth, and I knew each other before we came here. We're the Teen Titans. We're like a crime fighting group in Jump City, California. Raven's the only one of us that really has any magic. The rest of us can do other stuff."

Lupin now was in shock. "So four muggles are attending Hogwarts?" Gar nodded. "Why?"

"There was a daemon in the Forbidden Forest, and we've dealt with daemons before, so Dumbledore asked us to help. We've already defeated the daemon, but Dumbledore asked us to stay in case another one comes."

"The lights above the Forbidden Forest, that was you and your friends fighting the daemon," Lupin hypothesized.

Gar ignored him. He was starting at the ceiling, not really interested in what was being said. Instead he was imagining Terra. He was imagining making her laugh again, making her cringe at his tofu concoctions again, anything again.

Lupin was more interested in the Titans. "You said that each of you had powers?"

"Yeah, Robin- er, Dick, is our leader. He can do karate and stuff, and he has lots of cool gadgets. I can turn into any animal I want. I'm known as Beast Boy. Starfire, or Kori, is an alien from the planet Tamaran. Actually she's the princess of Tamaran, but she can fly and shoot starbolts. Cyborg, Vic, is well a cyborg-"

Lupin interrupted the changeling, "What's a cyborg?"

"Half-man half-machine," Gar explained. "And Raven can do magic, sort of."

"So she's a witch?"

"No," Gar said. He thought for a second. "You should probably talk to her about that. She doesn't like people to know about her. And then there was Terra." A look of happiness overtook Gar. "She was so beautiful. She could control Earth: rocks and stuff. She was so noble." Gar was zoning out. Lupin brought him back.

"What exactly happened to her?"

Gar's eyes became wet again, and fresh tears spilled onto his cheeks. "She was a Titan for a while, until she betrayed us. She was working for our worst enemy. She didn't know what she was doing, though. In the end, she saved us. She sacrificed her own life to save us." Gar rubbed the water out of his eyes.

Lupin thought thus over. It was an extremely sad story. This kid before him had been through a lot. He then remembered something that bothered him. "You said that you and your friends had faced a daemon before?"

Gar looked at the teacher surprised. "Uh huh. Why?"

Lupin calculated his words. "It's just that daemons are very rare in this dimension. In fact, I never thought I'd come within a kilometer of one my entire life."

Gar fidgeted in his seat, thinking of how Lupin would react is he found out he had a half-daemon in one of his classes. "I don't want to talk about that." Gar trusted Lupin, but not enough to divulge his best friend's secret which she had only just told to the Titans.

Lupin nodded. This was a lot to take in. He looked up at Gar. "You should probably go on to your next class." Having said that, Lupin stood and went to Dumbledore's office to confirm what he had just heard.

A/N: Sorry this chapter was so boring, but I needed to do some explaining. I hoped you liked the Terra tie-in. FYI: The chapter title Ghosts of Gaia is referring to Terra. Gaia is Mother Earth in Greek mythology. Please review!
