After a lot of thinking and some helpful suggestions I've decided to end the year making a start on my old sea elves. These could form an allied contingent to the 80's empire force I'm working on. Not strictly by the armies book but they will make a nice bunch of merchant guards from a sea elf quarter of some city or other.
They can also venture deep into the interior of a long dreamed of jungle/volcanic island. Also inhabited by Slann, Dark Elves and who knows what other evils, probably some Norse maybe even Nipon or Cathay.
