They're numerous, most focusing on harvesting the orange grass and turning it into cardamine so that it could be sold outside of the Nation. And the ones in power often change as Malta's political stage is ever-changing. The reason they're there is because without this trade our economy would most likely crumble under the need for outside resources while cardamine is our main export. I don't want to point fingers so I won't name any of these familias, but I'm sure if you look back at Malta's recent history you'll find more than a few. The temptation to point fingers at the Contari and blame them for the not too recent civil war was there, but she chose not to.
