South Ibra was a southern province of Ibra that the Heir of Ibra occupied when in rebellion against his father, the Fox of Ibra. When the Heir died of coughing fever, the on-again-off-again war between the two portions of Ibra ended. South Ibra lay between Ibra and Darthaca.
South Ibrans spoke Ibran with a decidedly melodic intonation; a governess of Iselle dy Chalion who was from there taught her to speak Darthacan with a strong accent. Cazaril had some work to do teaching Iselle how to speak correctly.
