Sheska was a librarian, who was responsible for organizing
and keeping
records of all of the books in the First Branch of the
Central City library. However, because she spent more time
reading books than organizing them, she was fired. She has a
photographic memory when it comes to books, and her ability
to recite them verbatim was a great help to the Elric
Brothers for recreating Tim Marcoh's book after Scar's
battle with Lust and Gluttony destroyed the library. She
also helped Hughes recreate State Military files lost in the
library until he fired her to save Sheska from the
military's higher-ups. After Hughes' death, she tried
investigating his death herself, and succeeded in learning
the strange discrepancies about King Bradley's secretary
Juliet Douglas, which is the same information that Hughes
discovered before he was killed. Sheska explained her theory
to Winry while Winry was in Central, and both decided to tap
the phone lines to King Bradley’s Secreatary. This confirmed
the discrepencies regarding Ms. Douglas, and Sheska
subsequently fled to Resembool with Winry to escape Maes
Hughes’ fate. Sony's Aniplex anime DVDs and website spell
her name as Sheska, although FUNimation's anime DVDs and
television closed-captioning spell her name as Scieszka.
