The world of the Black Panther, the Marvel Comics hero who hails from the fictional African country of Wakanda, is about to get bigger. Marvel announced on Friday a companion series, World of Wakanda, which is to premiere in November.

And just like the current Black Panther series, which is written by Ta-Nehisi Coates, the author and a national correspondent for The Atlantic, the new comic will be written by newcomers to the industry: the feminist writer Roxane Gay and the poet Yona Harvey.

“My agent was not thrilled that I was taking on another project,” Ms. Gay said. But learning to write comics exercised different creative muscles, which she said she found exciting.

“It’s the most bizarre thing I’ve ever done, and I mean that in the best possible way,” she said.

Her story, written with Mr. Coates, will follow Ayo and Aneka, two lovers who are former members of the Dora Milaje, the Black Panther’s female security force. “The opportunity to write black women and queer black women into the Marvel universe, there’s no saying no to that,” she said.
