Kisri of Bren Tril

Queen Kisri was a part of the Makian Pentatouria. She ruled over Bren Tril, a small peninsula in eastern Makia, and was infamous for her forgiving, carefree, and peaceful nature.

Having died in the Invasion of Bren Tril, she appears only in Deserter. However, she is mentioned in the first two books of the central series. Although little is known about Kisri, it's evident that she was considered to lack the authority it took to be a ruler (at least in the eyes of Aurora and Valentine).

In Deserter, Aurora mentions to Valentine that Kisri is "caught up in the world of the heart" and is allowing her immature indulgences to ruin her throne. When Aurora and Valentine later start their own relationship and recognize the irony of Aurora's statements, they both agree that Kisri's indulgences were more of a carefree nature rather than an immature one.
