As a writer, we play a voyeuristic role in our characters lives. Chasing after them, recording their actions, we keep a close eye on them. The above image puts into images your feelings of putting your character under glass, watching them grow and develop in a world of their own. Or, perhaps, this image inspires you to write a microcosm, a safe haven out of touch with the tragedies of the rest of your novel. Perhaps this is where your main character will seek rest and solace. Or maybe you can use it as a juxtaposition to the evils that have grown unchecked in your fantasy realm.
