Ha ha ha! For some reason, I find that to be very funny! Ga ha ha ha ha!
EDIT: Okay, okay, here goes:
Chrono Trigger & LBT:
Starting in the Land Before Time dimension:
One day, while exploring a previously unknown part of the Secret Caverns, Littlefoot, Cera, Ducky, Petrie, Spike, Chomper and Ruby discover a strange, blue circle. What is it? What purpose does it serve? Why is it even here, seemingly floating in mid-air? Touching it seems to do nothing - it's just... Hanging there... How strange!
Chrono Trigger dimension (a considerable amount of time after defeating Lavos):
The heroes of the Chrono Trigger have returned to their own eras, and the portals have all closed down, including those located at the End of Time/Farthest Reaches of Time - or have they?
1001 A.D.:
On a warm, sunny afternoon, Crono, Marledia and Lucca are walking through the forest, when a mysterious beam of light appears, stretching high in the sky. They walk towards the light, tracing it to its source: a gate! But, why did it so suddenly appear? The gates all shut down a long time ago, shortly after defeating Lavos! Intrigued, Crono, Marledia and Lucca activate the portal - and get flung to the End of Time! How...??
2301 A.D.:
After the defeat of Lavos, Prometheus/Robo returned to his era, now a bright, happy future abuzz with people and activity. Belthasar is also alive and well, having begun his work on Chronopolis. *Chrono Cross reference* One day, while traveling to the Kingdom of Guardia on a matter of importance, *I might change this part later if I think of something better* he too comes across the same beam of light, and upon touching it, he is also transported to the End of Time... Yet he did not activate it...!
601 A.D.:
The frog-knight Glenn has long since reverted to his human form... While out on an errand (somehow involving the Masamune/Grandleon specifically; need to work out the details), he comes across the gate as well...
64999999 B.C.:
While investigating the newly-discovered Singing Mountain, Ayla also finds the gate, and, well, you get the idea...
11999 B.C.:
After exacting his revenge against Lavos, Magus also went home to his old era: back to post-Zeal. That magical kingdom would never exist again... His search for his sister Schala/Sara began immediately. But, where could she be? Magus knew the task before him was to be a difficult one; perhaps Schala had perished altogether, engulfed in the eternal sleep of time...? No, he knew that such a fate had not befallen his beloved sister. Magus would find her... Or die trying. He had to...
All that remained of his life was intertwined with her; the whole point of his existence after being taken to the Middle Ages as the boy he no longer was - that child that hid his magical potential so well, the child Janus/Jyaki - being raised by Ozzie/Vinnegar, and waging the war with the Mystics against Guardia so he could gain the power to summon - and eventually destroy - Lavos... All this, on account of her... His only friend, a constant companion torn so violently from his child self...
Even his dreams were haunted by her presence. And of course, there was his cat, Alphador/Alphard, who had somehow survived... So, Magus reasoned within himself, that if Alfador had survived, then Schala must have, too...
One day, while flying around the land, Magus noticed that another mass of it had risen from the ocean depths. Many searches of this new land proved futile, however. Yet, how odd that a gate seemed to appear out of the middle of nowhere, on a particularly windy day. Vaguely interested at the ominous spectacle before him, Magus pondered the possibilities. Perhaps this gate was created by the Entity, who might know Schala's whereabouts? With this thought in mind, Magus stared at the blue orb. He had no means of directly controlling it, and yet, upon touching it, the gate also engulfed him, taking him, slightly surprised at its activation, to the Farthest Reaches of Time...
End of Time/Farthest Reaches of Time:
There he stood, the same as ever, under the lamp post. Gaspar/Hasch knew that something was going to happen, though. He could feel it, hanging thick in the air. Something was once again exerting a force upon all of time... He knew that more guests would appear soon... More than usual... Yes, things would get very interesting. Though, to what degree... Even the old man didn't quite know all the details...
Suddenly, out of the blue, a giant gate appeared in the room to his right. Gaspar wasn't entirely surprised, yet the SIZE of the gate was a sight to behold, and what came pouring out of it, even more of a spectacle: there, among the blue void, filling much of the space of the room, stood the heroes of time, aghast at their new surroundings. This was the last place any of them expected to wind up... What was more, this gate didn't seem to close down... It seemed to stay open, as though it were... Waiting for someone... Or something...
Talking with Gaspar only added to the confusion. None of them knew the reason why they were here, least of all Magus, who was almost irate about not only failing to find his sister, but now, being taken back here? Again??!
Land Before Time dimension:
The seven curious dinosaurs stared at the blue circle. They had never seen anything like it before. None of their folks had ever spoken of such a thing. It sure seemed strange... Touching it seemed a pointless task, as limb after limb seemed to pass through it, but nothing happened; as though they were just touching air. (Pointless, that is, until after the events which transpired in the Chrono Trigger dimension...) As Ruby reached out to touch it again however, it grew VERY large. Terrified, the young dinosaurs tried to run away from it, but alas, whatever this blue circle was, it pulled them back, sucking them all in; not even Petrie could manage to escape it... And it spit them out, shrinking down again to its normal size.
*Into the Chrono Trigger dimension!*
End of Time:
But this wasn't the Secret Caverns anymore. Where, and what, was this weird place? It was dark, and sort of creepy. Mists surrounded the area, but it seemed like the dinosaurs were too high up on this strange ledge for the mists to actually reach them. This, very strange ledge, with weird, prickly stick-like things all around the edges... *The fencing for the "rooms" at the End of Time* But, they weren't sticks. This place was so mysterious - it didn't look like any place that they had ever seen; their folks also knew nothing of such a place... Even the Far Walkers had never mentioned anything like this. And, who were... They? WHAT were they? Those creatures, up ahead?
CT-POV:
Suddenly, after a few passing moments of trying to figure out just why there were there, a curious scene unfolded before the heroes, for out of the gate, appeared seven dinosaurs! Ayla was taken aback at the sight, reflecting on her encounters with the Reptites. Even Magus' thoughts were distracted for a moment on account of the new arrivals. Seeing their mixed expressions of bewilderment, wonder, and fear, his composure was regained. (As though it had ever been fully lost; his expression had never waivered...)
*End crazy basic fanfic plot outline*
*Begin shameless (ful?) plug*
Behold the crazy spectacle within, fraught with conflict, unanswered questions, and potential mayhem! What force has brought this unlikely pair of sevens together?! Will Littlefoot, Cera, Ducky, Petrie, Spike, Chomper and Ruby find their way back home? What will they think of these strange creatures? What will the heroes of time think of these dinosaurs? Will Cera's ego and Magus' ego clash with one another, potentially resulting in a fight?! Will Crono ever say anything that WE can hear?! How much Science does Lucca REALLY know?! Stay tuned... Maybe!
*End shameless plug*
Hmm... A Super Gate... That's no ordinary gate, that's for sure! (The idea here, for those who have played Chrono Trigger and have given it enough thought, is that, because Crono, Marledia and Lucca activated this Super Gate - which even stretches through dimensions - it would activate normally; however, once activated, it would activate in other time eras if certain entities approached it, but only certain entities. (Sort of like in Chrono Cross, how, after the storm of ten years ago, the FATE supercomputer would only allow the Arbiter of the Frozen Flame to access it.) Since the rest of the Chrono Trigger team activated the gate at around the same time, they all got transported to the End of Time, in lieu of the Conservation of Time theorem. (It's only called this in the US version of Chrono Trigger, though. In the Japanese, it's only mentioned, without a name. Also, it is stated that the four - or more - beings must be from different eras. Lastly, the Entity is never specifically called that in the Japanese version. For a more in-depth understanding of Chrono Trigger the way it was meant be, as intended by Square-Enix of Japan, seek out the Chrono Trigger Retranslation, at the Chrono Compendium. A few plotlines WERE affected directly by Ted Woolsey's "mistranslation...")
