Idris Alooma

Idris Alooma was mai (king) of the Kanem-Bornu Empire, an African empire that constituted what are now Chad and Nigeria. During Alooma's reign (c. 1564-1596), the Kanem-Bornu empire is generally considered to have reached its zenith. Alooma's deep Muslim faith led to substantial reforms in the empire, including, but not limited to, a variety of improvements to infrastructure and an expanded interest in trade.

Idris Alooma in "Two Thieves"
Like every person who lived and died on Earth, Idris Alooma was resurrected on Riverworld at the physical age of twenty-five. He became part of the new community of Bornu under the reign of Musa ar-Rahman, eventually becoming a minister to the neighboring community of New Constantinople, which was ruled Alexios Komnenos. In the period prior to the war between Bornu and New Constantinople, Komnenos made several demands of Bornu that would render it subservient to New Constantinople. Alooma angrily refused these demands. While Komnenos was tempted to simply kill Alooma and let him be resurrected somewhere else on the River, he knew that his own minister to Bornu, Michael Palailogos, would face similar treatment if he did.
