Hello, I'm trying to adapt some of the army books for the minor factions in the Warhammer Armies Project, a website that is doing great work continuing the legacy of the old world. I've done the Pirates of Sartosa and the Vampire Coast. There aren't available models for the Pirates of the Vampire Coast so I imagine there'll be a lot of kit bashing. Or Warhammer: The Old World makes it a new playable faction with a it's own model line, that would be totally cool.
Here is a list of sources of miniatures for Pirates of Sartosa.
