Clysene

Daughter of Iscelais and Ireina, younger sister of Alvion.

A free-spirited and prideful girl with a great love of sport. Would've preferred to ditch the island to join her uncle's exiles, if only she didn't hate him so much.

Survived the Endless Nightmare relatively intact, with emphasis on the "relative". Turned to intoxication and promiscuity to cope with her trauma, which went about as well as could be expected. 

Turned traitor against her father, and was killed by him in the end.
