Silvia is the resident tailor in The Omphalos. She can create or mend all of Cyrus' garments throughout the game, including creating new armor for him to wear as the game proceeds.

She has a significant stutter that she can only control by not paying attention to whatever conversation she's having. In order to achieve this, she expends most of her focus on sewing or crocheting something, which initially makes her seem significantly distant and unapproachable. As her story progresses, she becomes much more personable, and her unapproachable nature diminishes in favor of her more cheerful but stuttering self.

Of note, her story does not involve her relieving her stuttering, but involves her being less absorbed in her work. Accepting that she has a stutter is part of her character growth.
