I think that words you could use to describe this time line could be Present and Prologue. Moreover, I meant only OC's, as anything connected with cast characters is quite intuitive and logical after all. Yes, it is up to me to decide the order. But this is a one-side view. After all, I'd be influencing other ponies the same way they'd influence mine. Meaning, that they could also make references towards my pony in different topics. Of course, it's possible for me to explain things. Example: I take part in two RP's, one in Canterlot, second in Ponyville at same time. Of course I can say in Ponyville one that I was in Canterlot and met this pony. And I could say in Canterlot that I'm heading towards Ponyville (which is true so far in RP I've started ;P). Yet, one problem remains. Until I'm finished with Canterlot role play, according to the time line stamp, I'm not allowed to make references to the story that was upheld there in Ponyville RP. Because it's past, but this past is not yet solved, moreover, I don't know how will my interactions with ponies progress. Meaning I can finish having different attitude towards them.
