See what arrives to empty spaces
If I go sit somewhere that looks as empty as a blank piece of paper and I simply look around… stare… blink… turn my head… before too long, I nearly always see something appear. The Elf Elders remind us often that our imaginations can fill up very big spaces.
I don’t have to strain to make something happen or to make something out. In fact, it is better to let my mind wander, because this allows characters to comfortably wander in.
Once something (or someone) appears, I can often just follow it (or him or her…) to the beginning of the story. The character usually knows where it is going.
