Saka was an old Firemaid who lived in Lavadome during the Age of Fire. She was retired by active duty and regarded as a Firemaid "of distinguished merit" (one of the three ranks for the Firemaids who could not be employed any more in battle).
At some point of her service, she was involved into a fight with dwarves and carelessly put her head into an hole where a dwarf struck her ax into her head.
Saka survived, despite having her head damaged and deformed by the hit, and appeared to have been mentally affected by the wound: she was met by Wistala while babbling about "flowers and stars" by herself.
By the time of Wistala's arrival in Lavadome, Saka was now aged and possibly ill, with her scale turned unhealthy and almost yellow in color.
