This is a good discussion on why time travel cannot/should not exist, but that was not the question/point of this sub. It is asking what your world would be like if it DID.
So we are in the realms of pure fantasy, as Time Travel is out of the pale for Hard Sci fi for the reasons already posted.
Obviously the accepted effects of time travel cannot happen otherwise it would not fit the premise that Time Travel does exist.
To avoid this, you need to consider time travel as a powerful Plot device and by no means allow unretricted access to this to the PCs. If you want the PCs to go back in time to kill dinosaurs, why not? The dinosaurs all die eventually and few make any real contribution to the future, except perhaps as fossil fuel and curiosities for scientists.
So what would keep it from being rampant?
1. Time is a river - a few stones dropped in will not affect it's course. There may be a few ripples but over time these work themselves out.
2. The Gods. Being by some accounts outside of time, they can easily reach in and make things right. Perhaps the gods are so detached generally because they are cleaning up the mess timetravellers cause.
3. Inertia of destiny. If you kill the great Baddies great grandfather, some other person very similar is born who fills the exact same place in destiny.
4. Active Defense. Any timeframe with magic-using beings is likely to employ seers of various types. They can, by seeing the future, act as warning devices aganist magical intrusion. They may not know (or care) that they come from the past, present or future. It is the affects of their intervention that the powers that be will likely seek to prevent. Those who stand to benefit might not take action, but those on the loosing side will definately take action.
5. Self Preservation. PCs will need to know that if they change too much, their own time might change radically. In short, it is in their best interest to be very subtle. Go to Comment
In an essay on time travel, the science-ficton author Larry Niven postulated that in any universe where time travel was possible, it would never be developed. His reasoning was that in such a universe, people would travel in time until they intervened in the timestream in such a way as to catastrophically interfere with their culture's ability to travel in time. Once time travel became an impossibility, the timeline would no longer change. Go to Comment
The famous professor Lirekfen Kcabreist in his his book "Beyond Yesterdays Humbug" Made note that, no one had ever claimed time travel because once you exit the present, you no longer exist in that time line and as such can not return to it. When I say return I mean interact. You therefore are unable to boast and claim time travel.
Lets take a person known as Jim, ourselves and our perspective on the three separations of time.
A denotes past.
B denotes Jim's Present
C denotes future.
Jim stumbles across a time machine and travels back in time. Even tho he lands perfectly at 1820 he cannot interact with it in anyway. He is like a ghost, unseen, unheard and definitely unable to change. Because what he is seeing has already happened you see. Even tho from his perspective he is at the moment. That moment has already happened.
The girl gets run over by the milkman, its already happened. Jim is powerless to change something that has already transpired. We know its transpired because of the numerous happenings that can be traced back to that event. Even tho he has traveled back from the (B) to (A) he cant change (A) from our perspective, because to us (A) has already transpired. The dog is chasing its tail.
He can of course observe (A).
Poor Jim can now however no longer return to (B) as (B) from his perspective and ours has moved on. He wasn't there when his boss burst into the room to catch him red handed at the scotch bottle, instead of doing his work. Jim was also,unable to breath out, in the split second after he time jumped and thus did not pass on the flu virus, to the tea lady who was just about to enter and offer him afternoon tea. So Jims future from our perspecitve is changed dramatically, in that same way as if Jim has suffered a fatal heart attack. Those who's time lines are connected to his are changed.
Jim cannot find a stable lock on the future, because it hasn't transpired yet. That is, the intricate and chaotic events, from which the time fabric is weaved, can at any one moment produce zillions of future outcomes. Because that trigger event has not yet transpired, one cannot jump to the next event or end result of the string of events. That future stone may not exist at all or be anywhere from a few milliseconds to hours from a predicted path.
Jim is lost in time, to time. He has no way of reconnecting himself back to a timeline that we can observe.
Lirekfen also goes on to observe and dispel, the possible link or theory that haunted houses and ghost n such are simply lost time travelers. Lirekfen was reported to have rebuked a student at one of his lectures once with.
"Did you not listen! At point (A) you can not interact with anything from that time. If for example you saw a ghost, you may stop, or scream. Those events however trivial would change the course of events. But we the observers know the course of events, we have history, we have evidence. Now sit down, before I really show you how to create ghosts. And next time, think of A and B before you mutter and create a C that shouldn't exist." Go to Comment
mm maybe I was too subtle in my above text. I was eluding too this thought. It might be of interest for a bunch of characters to end up together in this "outsidetime". A plot, a location, a world, in itself, fighting off whatever falls in with them and desperately trying to find themselves a "timehome". Go to Comment
Not much meat on the bones on this scenario but what CM discussed in the opening is solid, it would be better if it incorporates what Val provided on what would keep time travel rampart. Also, what Scras and AG provided of time travel in their worlds are both interesting and have utility value. Go to Comment
It started out great and I was sucked right in and then it seemed to run out of air. The rape thing was a great idea and a very interesting problem but there is no clues on how to fix this dilemna. They will remain guilty forever, even if somehow the bush is proved to be stolen...that really doesn't have anything to do with the actual plot that the PCs are involved with. I doubt the princess would get in much trouble for stealing a bush, regardless of its value. There are no clues on how to prove that anyway.
Just not sure what to do with it, but there is definitely something there! I loved the first half, just needs a better ending in my mind. Go to Comment
I like the formatting and the writing, but must complain of one thing: the plot is horribly linear, made to force a group of heroes into the story exactly as it is written. Oh, and they will be wanted criminals in a large city while being completely innocent - and are not likely to be able to prove it after the plot is over.
Don't get me wrong, you've shown what could be done out of this exotic mix - it could be easily enlarged to a mini-campaign, with the PCs falling into the thrall of the Lady, maybe even stealing the plant themselves; and at last recognizing her true nature, at which point she would promptly condemn the group to death. The payback would be more than sweet, whether just by executing her; or by proving her role in the invasion (smart PCs could even argue for peace between the city and the invaders). More could be made of this. Go to Comment
I most definitely agree. I was annoyed with how linear it turned out, but I figured any GM worth his salt could work within the spaces to make things interesting (as well as less linear and railroaded). Unfortunately, this is my first plot ever created, so I'm not shocked that it's horribly linear. Everyone has crappy beginnings. Just look at CP!
Thank you for the honest feedback though. I appreciate people being brutally honest, as I can see many flaws in all of my works. Go to Comment
Castoria was once a thriving and prosperous nation, a rich trade center for the surrounding lands. This all changed when, on one fateful night nearly a century ago, the Mist of Eternity rolled in and surrounded the land, obscuring more of the outside world as days and nights passed.
By the time the Mist blocked out the sun, a new light shone during what was assumed to be daytime: The Starpoint Spire, a mysterious place atop Castoria's highest peak in the northern-central region. Some say that there is some sort of building atop the mountain shining the dim "sunlight" onto the land, but it is only ever too bright or too dark to fully make out any structure, not to mention the mountain's immense height.
Not a month after the Spire's light lit up, the stars fell. Flaming rocks and debris from far-flung edges of space plummeted downward onto the eastern region of Castoria. Once the shower subsided, a strange energy from within the fallen stars transformed the eastern lands in what are now known as The Voidwastes, a barren gray land littered with craters and strange alien creatures (these can vary, but I had Pathfinder's Akatas in mind).
To the south, strange mechanism of eldritch origin are again at work after aeons of rest in the Ruins of Kchuthngnl, an ancient city of non-human creation that is estimated by scholars to be no less that five millennia old.
To the west, the once peaceful and serene forest, now known as The Plagued Woods, has been experiencing corruptions of the wildlife and humanoids living there. Some humans have reported creatures that appear not unlike a halfling, except that they can open their mouths to massive proportions to swallow creatures the size of an ogre.
When adventurers and citizens alike try to make an escape from Castoria, they are never seen again, and it is utterly unknown whether they found hopeful sanctuary or agonizing death withing the Mist's depths.
What is unknown to all residents of Castoria is that all of these events occurred because of the actions of a secret but powerful cult loyal to the Elder Gods who call the space between the planes their abhorrent home. The cult still lives on, larger than ever, and their plan is for the alien horrors to incubate and thrive within the dome of mist that now envelops Castoria, so that when the Elder Gods return as the cult's prophecy foretells, they will have an army of blasphemous creation at their disposal that they will use to make war with and enslave the denizens of the Material Plane.
