Zephyr is a brutal pirate who started this line of work in order to make money for his sick mother and to gain a noble title to marry the love of his life. His accent shouldn't be stereotypical pirate and more of the rough but loving kind of person. Feel free to include some words with that stereotypical accent just to make it feel like he picked it up a bit from his sea life. Zephyr is also a tiefling.
