Esra

Esla (エスラ, Esura) is the mother of Sinbad.

History
Esla was already ill by the time Sinbad was 14.

When Sinbad went to capture Baal she gave him his father's sword, and wished him luck. When Sinbad returned, a month had passed in the real world, and he found his mother lying dead on the floor of his house.
