I'm new to the forum, and kinda new to D&D multiverse in general. I'm happy that I've found this forum, and that there are still people, who read old source material. 'Cause (I hope I'm wrong) in my opinion most of modern stuff in fantasy is either necromantic skeletons of past settings without soul (5e materials on old settings, or lack thereof) or disrespectful to source material (WAoS for example), or something colorful and cool on surface, but bland underneath (when I think about Ravnica it's usualy "Sigil, but boring").
As you can probably see I'm not native English speaker and I'm quite sensitive about the topic. Please, forgive me bad English and that emotional talk. To the problem:
Do the petitioners have their own lifelines?
I'm DM in a campaign/metacampaign which mixes Spelljammer and Planescape whith Chronomancer's Temporal Prime (AKA "demiplane of time") . There are some serious time travel plots going on in the background, though the players haven't got to the dark of things yet.
To remind: every plane has it's own timestream, and every living creature has it's own glowing "lifeline" in the Temporal Prime. The more influential someone's life is, the thicker the his/her lifeline. When someone dies the lifeline doesn't just end, because one can influence others even after death. Instead it slowly gets thinner and thinner as it fades out (when it is very thin it's called "ghostline").
If I understand corectly, when you travel planes, then your timeline goes through several timestreams. If you go back to time when you haven't been born, the lifeline extends to that moment, but is visible only in those moment when you are visiting the past.
You cannot meet your past self. You can't even be THERE (doesn't matter the distance). There simply cannot be two version of you in the same time without reality trying to get rid of you.
The existence of petitioners seems to contradicts the law of time, because they can "live" in the same time as "their" ghostlines are getting thinner on the same or other plane.
Do I get something wrong? Can petitioners be considered not important (I doubt it) to time or they are important, but they are considered to be different people, due to their lack of past memories? Do you have any theories?
Thanks for any help.
