I have lived with you and loved you, and now you are gone. Gone where I cannot follow, until I have finished all of my days.
The main characters for 'The Seer and the Sword' made an appearance one night and then haunted me for over five years before I began to write them down. Does that count as inspiration? For me, characters tend to show up, stay on to help with the work of writing their stories, and then occasionally deign to visit after a book is finished.
