Merman. He fights his own battles but if he likes you and if he likes your battle he’ll chip in with his fishy minions and his trusty double-headed double-edged … whatever. I’ve asked him what on earth-and-ocean is the terminal-looking contraption he wields so skilfully; who made it?, did he make it himself?, can I get one on e-Bay?, and so on. He just smiled sweetly, gave me a slightly commiserative look and said that some things are better kept where they are: in the dark. Oh, well… I recommend him as an ally, however. He’s very good and he tells glorious fish jokes.
