I've just had a major plot breakthrough in my novel and it got me wondering if other writers experience this same type of enlightenment. In Chapter one of my story, the heroine, Tygra, is taking a walk through the forest with a friend. When writing that scene, I decided they needed a destination for their walk so that it wasn't just a mindless ramble in the woods and I introduced some ruins into the storyline to supply that destination. They were, in my mind at the time, a minor plot element. I used the ruins a bit later in the story, but again, as just a plot helper and nothing more. Until now. For the past couple of days I've been struggling with the question of "why". Why had Tygra had a vision of a volcanic island? What was its significance? Why there and not somewhere else? And, most importantly, what would they find once that reached that place? Then, waking me up before 6:00am this morning, the answer had come to me! The ruins. Well, their polar opposite actually but still the ruins were the "why". So, I'm just curious, do other writers experience this? A random element of a story, created for some minor purpose, turning into a major plot item as the tale unfolds?
