Sometimes the Art Comes First

Sometimes the art comes before the writing as in the case of this mouse monk drawn by the amazing John Bilodeau. Who is this fellow and where does he come from?  The module I was working on had already been written and was in layout, so it wasn't clear how to slot him in. 

Thankfully one of the playtesters (a DM in this case) had an epiphany and wrote up a scene that included him, along with a stat block and back story.  

Have you ever had to do this in your own writing? Let us know your thoughts in the comments.
