Hello! So I had an idea that involved allowing interaction between a mod that I'm interested in making and other mods, notably companion mods. I know that some mods use this idea to a certain degree (i.e. Julan being aware of Constance), but I'm not exactly sure how this is done. Also, I'm curious as to how far this idea can be taken (possibly adding new dialog to non-vanilla NPCs using only my outside source, though I'm somewhat doubtful there). I'm relatively new to modding, so I'd really appreciate the input.
