Cu Sith (Revenant Wings)

Cu Sith is a particular Yarhi in Final Fantasy XII: Revenant Wings. The Master Artificer, she is Tomaj's self-proclaimed apprentice, though Tomaj refers to her as "it". Cu Sith will set up a synthesis shop onboard the Galbana and help you Craft new items for you out of raw materials you find on the world map.

As she points out, her name is a misnomer, equivalent to calling a hume "Hume".

Story
Cu Sith was rescued by Tomaj when she was floating in the sky. She hit the wing of the Galbana, where Tomaj found her. Grateful that someone helped her, she decided to be Tomaj's apprentice, following him everywhere, lending her services to him, and bestowing upon him the title "Master Tomaj".

As Vaan creates more items for her, she sends him out on more and more missions to help her out. One such mission involves the hunt for the Everburn material. Tomaj also sends out Vaan for some missions to expand her forge.

When Nono comes onboard, the two have a dislike for each other. However, they eventually start seeing each other in a more positive light as they see each other work.
