While I'd intended to move on to my elk-men next, I've just finished off a couple of Mudlarks so I thought I'd slip them in now!
Crows sometimes hire little bands of them as local guides. Folks like these have been here too long to want to return to the ships, but something as valuable as a firearm would command a princely sum to such downtrodden people.
'Same species, same specimens', as the Biologis say.
Not a great deal more to say about them, but here they are anyway! Hope you like them :)
Oh, someone did mention the idea of making some scenery for a little Mudlark shanty-town/village which sounds like a great idea so expect some of that at some point in the future!
