So, I finally began writing my sixtieth or so first draft. And I noticed a small thing:
As sunset came the sky became a river of orange and gold. Maybe like a lava stream? Gyvaris might have been a red dragon, but as embarrassing it was, he never saw actual lava in his life. The only time he heard about it was from his mother, the rest was left up to the wyrmling’s imagination.
It's still well in WIP, but I didn't plan for this on the character sheet, it just came randomly and I just added
"Gyvaris spent his early years in a large forest, much like the one he later choose to settle in. His parents rarely ever went beyond its borders after he was born, and they never really explained why."
This did help develop Gyv as a character and establish that he has holes in his lexical knowledge despite his intelligence and resolve.
But I'm still afraid that this will lead to contradictions in other characters later.
This is a useful thing but how can I prevent it from leading to contradictions later?
