Isra is the older sister of Vitreus, and oldest daughter of Frossar. The apple of Isrun's eye, the Frostspear Matriarch grooms Isra for future Matriarch, (much to Frossar's concern, as he wants to be Patriarch himself).

Isra, however, is a dragoness without aspirations that doesn't seem to care about anything, or anyone. She is quiet, and does as told with little effort. Though a princess in all but name, Isra does not seem to enjoy her existence.

She was present at the start of 3006, in her last year at the Temple, when her little brother Vitreus got in a fight with Hayze. The situation did not appear to concern her, and nor did she intervene.
