So, I have not gotten anything published yet, but I have had plans for future novels including the one I am most way done with at the moment. As for the Details: It's going to be a multiverse existing where an older world used to be. There are higher beings that were once mortal before taking a specific substance into themselves and now they are indirectly existing across all the realities making up the fundamental parts of each world, as long as each part falls within their 'domain' as it were. (with one exception, but that's another thing entirely)
The reason I describe this is that I was going to establish that any universe their direct conscious selves inhabited could have no alternate versions of itself, as there could only be one of each of these beings. No alternate timelines, no alternate realities.
So, the issue is that at one point I decided that one of them would have a child who eventually tries to go back in time in the world in which their parent lives. They were supposed to leave an artifact in the past that helps the people living there in a variety of ways leading up to when they are born. With help from a mortal friend of theirs.
Originally I thought that maybe there could be a sub-realm to help sort out issues, or that the parent being would bring the ideas of the individuals into the present of the past if they accepted them. Though I am not certain how to solve that quandary, especially since the child would also be one of those beings albeit a new and fresh one while the parent would be in the present future. Suggestions would be appreciated?
