The trickster. The son of of Laufey. The clever character who uses his head and the materials in plain view to solve the insoluble and to do the unthinkable - which is obvious when he does it. My favorite characters to write... maybe because it's just a little close to my own nature. The trickster is not intrinsically a bad character. Usually the inverse, but a great trouble to the serious characters. Often at least amoral, poking fun at the po-faced and the rule-book. Paying the price for it too. The sort of friend you really need when things are impossible, and maybe the sort of friend you'd want to avoid when things aren't dire, because he'll make them that way. Just for fun.
A piece of every damn near mythology in the world. Glooskap. Loki. Hanuman (my personal patron :-)) Often slipping into disrepute as boss-gods grow sententious. Often the friend of the small and the weak. Surprise!
A mainstay of fiction too.
The Saint. Silk. and a few of mine... Benito. Bes. (ok, i'm up for more - books and authors with Loki.)
How do we make him work?
And why Leafy island?
