Terentian Elves
by Marc SaindonThe Grand Duchy of Terentias, capital Crossbones ("Ossa Crucis"), is a Thyatian conquest (that has changed hands with the Minrothad Guilds over 200 years), with 40% of its 25K population being Elves. It's also a pirate island that makes minimal effort to hide behind a thin veneer of a trade port.
In my fan theory, Minrothad folk speak Portugese (further establishing connections with some Savage Coast colonies). Perhaps Terentian Elves speak Spanish. Machetos is close enough. Maybe some Terentian Elves migrated further up north to help colonize Belcadiz in Glantri?
Another element is some loyalty to the Empire. Perhaps the Minrothad Guilds' rigid caste system and bureaucracy has pushed many younger Elves into trying to find careers elsewhere, leading them to create a colony, with both right-wing libertarian tendencies, centrist greed, and left-wing anarchist ideas try to find their place.
