Hello Kate. I love the inventress backstory you've given Fred. It occurs to me that Miles might wholeheartedly support any inventions she might perfect that provide an alternative to conventional uses of fire, such as a "flameless torch" or a solar oven, hee! He doesn't like flames very much.
Robin is an interesting character too. Hopefully the innkeeper won't send Miles out to gig frogs for the larder at the wrong time of the month!
