I feel you, author, I also write without thinking too much and end up getting screwed later... About the plot, I think for now, as the story is in the beginning, I think it's ok if the story was just them going on adventures and getting to know each other more deeply. About the world development, you could include, for example, DLC's mods, such as Bruma, ClockTower, or The Forgoten City, to further enrich the world of Skyrim, since he is in a real world and not in the game, or even enhance the mercenary job with a bounty system like "The Notice Board" mod. Anyway, if you use mods as a reference for your story in addition to the original game and its DLC's, there will be a lot of content to use in the story.
