"Heard for Himself"
A DW prompt inspired the free-verse poem "Heard for Himself." Menachem the blacksmith and Yossele the golem meet with two other Jews, who speak different everyday languages but are able to converse in Hebrew.
Yossele the golem and
Menachem the blacksmith
traveled together, and on Fridays
they always stopped early so they
could prepare for Shabbat.
Over on DW, a Fledgling Grace prompt inspired the free-verse poem "Impossible Wings." It went a little aside from what you suggested, but it does feature both Sudan and the mousebird, and something else quite new.
In Africa, the grass follows the rain,
the cows follow the grass, and
the people follow the cows.
At the border, a Sudanese guard
eyes the couple approaching.
"The Language of Resistance"
A DW prompt about the Godship Wanderers inspired the free-verse poem "The Language of Resistance." Two groups of escaped slaves meet in space for trade and socializing, helping each other along the way.

Netta and Chung-Cha worked together
to help people communicate, splicing
the language of resistance from bits of
English and Yiddish and German
and all the rest spoken by those
who had until recently been slaves.
From this I got the poem "Three Times," written in unrhymed couplets. All I had to do was put a beginning and an end around the middle! Because of course there are a few more necessary players. :D
