@Fiberglass Cyborg I
totally sympathize with that. Hopefully you got it worked out?
I had something similar where I knew i wanted my MC to be a teenager visiting family for the summer and unhappy about it but their parents had insisted, beyond all reason (in their opinion) that they visit the mom's family's business (a (unknown to the MC) magical inn). I'm intentionally aiming for cozy YA and steering clear of world-shattering stakes, so everything needs to be personal, limited and focused on the MC's world.
The underlying why i initially touched on was a family feud-- oh, hey, what if Romeo and Juliet lived, married against both family's wishes and had a kid? Wrote it, kept moving.
And found it wasn't enough. It felt low stakes and kind of lame and didn't work with the whole, magical inn, central plot location. In the course of writing, found that, oh,
actually the MC has magic but the dad's family cursed them and locked away their magic but it keeps poking through in strange and disconcerting ways. I went back, re-wrote the early reveal scene, and moved forward.
And found it wasn't enough! It gave me a lot more to explore and work with, but it felt incomplete. I toyed with other ideas and then over the last few days decided,
oh actually the MC's dad is an elf and they're mixed race. And,
oh actually I can make elves be a bit like the Sidhe with bargains and agreements and that's how they fuel their magic. And,
oh actually, etc. I still need to go back and re-write the reveal scene, but I may move forward for the time being and come back to that particular scene-- knowing I'll need to edit a bunch in general.
Though, if anyone's looking for an explanation about how pantsers/gardener writers write, well, there's my iterative thought process for plotting and background.
