Thats a different quest part.

Speak to Roh'kenmou (the Nu Mou in Old Dalan's house), and find Filo in the south-east portion of Rabanastre
Lowtown, South Sprawl. Find the Curious Woman by the fountain in Rabanastre,
Southern Plaza. Speak to a "Merchant" in Muthru Bazaar, then find the Sotted
Imperial inside Yugri's Magicks, East End. He demands you to speak to the
Curious Woman but she is no longer by the fountain, so find Kytes in northern
Lowtown, North Sprawl. Return to Filo in south-east Lowtown, South Sprawl to
find the Curious Woman. Return to the Sotted Imperial in Yugri's Magicks to
obtain the Grimy Fragment. Hand the Grimy Fragment to Roh'kenmou.
