Swashbucklers and Musketeers get companions from Valencia, the Hermit Crab and Ridolfo Cappofero. Privateers get Iago ( Unicorn Rogue ) in Port Regal I agree with Marleybone Patriot, why the fascination with clockworks? ( shudder )
Well, by Valencian companions you mean companions from Valencia? Well there is the unicorn swashbuckler in sivella, ridolfo. Then there's Iago, the unicorn rogue. Then there are the crabs and guinea pigs. Louis le bisque and gaspard de vole are both from Valencia. We probably won't get a clockwork companion, our crew won't be happy about it.
I think some people just want a different sort of.....variation in there crew. It's nice with so many different creature crew members but sometimes you need/want something mechanical to even things out. That nutcracker companion's a good example, but when we do go back to Valencia and if we find the Toymaker there, he could build us a completely different style clockwork (with no links to the Armada) and program it to fight for us and us only. This idea's been suggested numerous times and as a great twist to that old story, we could have our clockwork named "Abel". Imagine, Kane and Abel: Round 2 BTW, gaining control over a clockwork, I imagine, wouldn't been too much harder than how we gained control over Monkey King.
