Lightning Jack is a member of the Teornarch which is basically Song of Steel's version of Sea Elves, or as everybody else will probably say an excuse to play pirates with Cornish to West Country accents :-)
We recently did a proper "Teornarch Special" on a particularly brilliant weekend in July which involved a hunt for hidden treasure, Mermaids, Sirens, Sharks and other such sea monstrosities. Karl took a load of pictures which you can find here. The general consensus amongst the players is it was a fantastic dungeon. Quodos to all the monsters who thought nothing of diving into the water to make sure it was a suitably wet dungeon :-)
