In Geneforge one, Masha is the leader of the Shloai's who do not follow Trajkov.
Astrov escaped whist Anfisa was killed.
She is seen by the PC to be quite pretty, in an exotic way.
If you retrieve a missing key, she allows you to look in a journal which describes the Sholai's voyage to sucia isle.
She then asks you to take sides and gives you a letter to give to the hidding Astrov.
In Geneforge 5
