This is cute. They remind me of fantasy lightning bugs. I can see these adding a lot of neat flavor to a camping scene. Thanks!
I have an idea for a Pyromancer NPC who might just happen to attract a few of these harmless fey who enjoy basking in the warmth of his fiery destruction.
Holy carp! This is the best flying machines ever! Beer-Jets, Ahoy! The letter was a great intro. I was reading, wondering what a gnome opening up a store/bat could have to do with a flying machine, then the ever-full mug, then the flying ever-full mug, and the transition from mug to machine was so gnomishly appropriate that I had to read it twice. This is great stuff!
It's a fantasy virtual reality helmet? Interesting idea, and nice execution, but I'm not sure I would want to use it. Much like I don't tend to use drugs or addiction in most of my fantasy games, this feels like it would hinder the game more than help it. Not bad.
