Tyrena was the daughter of the last Khanar (ruler) of Tilbor. She was sometimes called "Khanara" although never officially, and for a while was the regent for her sick father and de-factor ruler of Tilbor.
Eleonyd tried to marry Tyrena to Rhecyrd, from a northern clan. Tyrena, though, wanted to rule in her own right. That caused a struggle between traditional northern clans, who would not support a female rulers, and who wanted Rhecyrd on the throne; and the southerners who knew and trusted Tyrena.
The struggle got ugly, but before a full-blown civil war, Tilbor got conquered by Lord Chayar of Telaryn. Tyrena fled to Bovaria with all her jewels, and probably married a Bovarian High Holder: Iraya or Ryel.
Tyrena was very blond and very strong-willed, as good with arms, if not better, than her father.
