Trivis

A trivis is a complex idea of an item based in multiple timelines. To put it as simply as possible, it is an object that you put into your present by influencing your past. To start, there is a base timeline with two branches. An item, the trivis, is willed out of one branch and into the other. At this branching point, a different version of you will influence the non-primary branch to instantiate the object into the branch where it doesn't exist.

In Practice

You come back home after a long night and realize you don't have your key, you left it at home. You will your past self to have gotten the key. This takes the timeline in which you have your key and merges it in, so you spontaneously always had your key. This would normally lead to no one ever knowing a trivis could be a thing, if you change your timeline to have always had something. However, all points prior to the merging will remain intact. So, if you're out and realize you don't have your key, do things based on that change in the timeline (ex: call a friend to see if they have a spare), all of that will still have happened, though you have always had your key.

This can become infinitely more complex, having two timelines diverge so entire nations rise and fall differently. Or, it could be such that one branch goes on a quest to accumulate enough wealth to purchase an expensive Murn that is used to make a highly nutritious synthetic honey, then that murn will be brought into the timeline where that quest never happened.

Meta

Trivis are extremely rare objects, no one has been able to willingly create one; it has only ever been observed by the testimonies of those it has already been created for. It appears that, due to the trivis being created, the two timelines affect become intertwined for a length of time afterward. There does not seem to be a reason behind its occurrence either as it has been noted in mundane things to important things. One major event where this is detailed is in the Battle of Dagjvamzha.

This a wonderfully complex and bewildering mcguffin item of "Bill and Ted's excellent adventure" quality. They have a time machine and are jailed. They say that they will hide a key here later so that they can get out now...and so find the key they have hidden in the cell in the future. Except this is retro conversion. Fun.

So what about the timeline you that had their keys and now doesn't; are you just not worried about them or is there some form of temporal empathy?

Hmmm... I haven't thought about that. I'll have to come back to this article sometime to add this!
