Cool idea!!! Also, I think Brookeira stopped posting, so this is perfect!!!

I love PJ!

DOCTOR WHO!!! ALWAYS!!! DO IT!!!!!!!!!! MWAHAHAHAHAHAHA!!!!!!!
Please keep in capitals.

Luna Lovegood? Or maybe Micky? (I want to find out what happens to him when he *SPOILER* stays in the alternate dimension. *END SPOILER*)

I think I may have to include other characters from PJ, because of the course of the story.

Aragorn strolled calmly along the terrace, gazing out at his kingdom of Gondor. His hand, resting on his sword, twitched slightly. He frowned.

"There's something not right..." he murmured. He'd had this feeling for days now and couldn't shake it off. His wife, Arwin, glided out to join him.

"Aragorn, you're starting to worry me. What are you talking about?" Aragorn didn't respond. He was simply staring off into the distance, his eyes wide. Arwin frowned deeper. "Aragorn, please! What are you so worried about?"

"I have a feeling it's something related to that," he replied. A swirling vortex had opened up like a black hole and was now making its way towards the castle. Arwin gasped.

"What- What is it?"

"I know as much as you do," Aragorn reminded her. All too soon, the vortex was there and gone, Aragorn with it.

Percy and Grover were having a worrying conversation.

"What do you mean the titans are rising?" Grover rolled his eyes.

"What I mean, Percy, by 'The titans are rising', is 'THE TITANS ARE RISING!!!' I think that's part of the reason why the nymphs are having such a hard time with-" All of a sudden, a swirling black hole appeared and spat out a middle-aged man with shoulder length brown hair.

"Well, that's sure not normal," Grover observed.

"Thanks, Nature Genius," Percy muttered. Aragorn glanced around in shock.

"Wh-where's Gondor.?"

Percy: "What?"

Grover:"What?"

Aragorn:"What?" 

"Oh no." 

I hate to sound stupid, but Ara-who? 

Aragorn paced the shore of the lake. 

"So where is this place?"

"Camp Half-Blood. It's a place for demigods to stay safe." Percy explained.

"And demigods are...?"

"The children of gods, and that's all you need to know. We have bigger problems: The Titans are rising again." Aragorn halted. 

"Titans?" Percy sighed.

"I'll ask Chiron to explain it later. Right now, just know that the titans are very big, very bad, and very powerful." 

"Then how do you propose we-" Aragorn's inquiery iis intterupted by a high-pitched ringing. A blue box, smoke pouring from broken windows, is spinning out of control straight towards the two. Both scream and jump out of the way just before it crashes and erupts in flame.

"Apollo!" Mr. D shouts from the porch, where he saw the whole thing. The doors of the wrecked box swing open, and a man, definently not Apollo, climbs out.

"Apollo? Where?" He demands.

"Who are you?" Stammers Percy.

"The Doctor!"

"Doctor who?"

"HAHAHA!! You said it!" The curious man dives back into the sideways box. "And with me is... oh, dear. Oh, my- you alright? You ok? Good. And with me is...." The Doctor climbs back up again, dragging with him a very confused looking and battered boy. "Eragon!!"

"Where's Saphira?" Eragon mumbles.

"She'll meet us here later." Promises the Doctor. "So, then. What are we all here for?"   

Presently, there was a screeching noise above. Everybody looked up to see a beautiful blue dragon fighting in the skies with Festus.

"Saphira!" Eragon shouted. There was a pause. "I don't care if he attacked you! Just-" Another pause. Eragon frowned and turned to Percy. "Who is the Dragon's rider?" he demanded.

"Well, he doesn't really have a rider, but he only listens to Leo." Just as Percy finished, Festus turned and headed back towards bunker 8, Leo's personal workshop. Saphira glided downand landed next to the group.

"Well, then." The Doctor staightened his bowtie. "Are we expecting anyone else?"

"Well, we weren't really expecting you in the first place, so-"

"What in Starclan is going on?"

"Apparently we are."

A large, fluffy white cat with big paws came strolling over.

"Where is this place?" Percy stared.

"That's a talking cat." The cat frowned too.

"The name's Cloudtail, talking Twoleg." The Doctor and Percy glanced at each other and shrugged.

"Wierder things have happened," they chorused.

"Wierder?" shrieked Eragon. "Wierder things than this have happened? What kind of wierder things???" 

Hey! Sorry I haven't been able to post for a while. We've had company.

"OK, NOW I think we have everyone." Percy prayed as he paced the shore of the lake, Eragon muttering about what wierder things than this could have happened, and Cloudtail looking baffled.

"So from what I've mangaged to gather between visits, is that in everybody's world, dimension, life, whatever, things have been going wrong. The Doctor claims that every different planet he's been too, there's been word of a dark presence or something. Aragorn said that the kingdoms of men and... well, everything has been fighting, dark presences and blah blah blah. With Eragon, he says that the empire seems to be rising again, and Cloudtail said that the Medicine Cats have been recieving strange visions of the Clans, even Starclan, being crushed underfoot. I believe I have an explanation." Here Percy paused, basking momentarily in the obvious suspense of his companians. "The Titans are rising again. And they've gained access to other dimensions."

"Say WHAT????" Chorused the company. Percy shrugged, opening his mouth to say something, but then Aragorn jumped in. 

"So how do we defeat said Titans?" He demanded. Eragon added, "Can they be defeated?" 

"Well," Began the son of Posiedon. "I think they can, but first we'll need some help." He turned to the Doctor. "I'm gonna need you to pick some people up."

Now I need CBers who want to be in the story! 

I don't know if there's a specific storyline for this or anything, but this kind of makes me think of the Wood Between the Worlds from The Magician's Nephew, the first Narnia book (admittedly, one I usually skip, I don't know about anyone else),so I don't know if it works for the story, but it would be kind of cool if they went there to travel between the worlds and defeat the Titans.
