At the risk of being a negative Nancy, have you thought about down-scaling the mod? You seem to have multiple large plot threads (Empire vs Thalmor, Shezzarines, Gods, etc,.) that would honestly need a large game studio to be done well. You honestly might be better off just focusing on the Caesia character and making a scaled down quest for her. The type of questline you're proposing on doing is something that a LOT (and I mean a lot) of mod authors have tried to do before (even ones with large teams) and the vast majority of them have ended up not going anywhere and the modders involved burning out. Many of these large scale modding projects that do end up getting done tend to be of fairly low quality (Summerset Isles being a prime example). Even a mod like the Forgotten City (one of the better quest mods available) took years to make and it's far smaller and had far more people involved then what you're proposing to do. You don't have all the people you need to finish this mod and honestly I think you would be better off just trying to make a good follower mod with a decent questline then trying to make what is essentially a massive expansion pack. Everybody wants to make a massive questline and story. But you need to know what you can swallow and what you can't. I mean for god's sake an Empire vs Thalmor storyline would be it's own massive undertaking by itself, but you're thinking it will be a side plot. A side plot. You don't have the resources to do what you want to do mate.
