Retrieval of Ilia's Memory

The is a particular plot diversion in Twilight Princess that operates due to the aftermath of the Ordon child abductions by King Bulblin and his troupe. After the children quickly quarantine themselves from their persuers inside Renado's house in Kakariko Village, Ilia, the eldest, is reported to have taken shelter in Telma's Bar, a pub within the confines of Hyrule Castle Town. When Link goes to see her after visiting with the other children in Kakariko Village, he realizes she now suffers from severe memory loss as a product of her abduction.

Procedure
In order to restore her memory and complete the quest, Link must have found first the Mirror Shard in the ancient Temple of Time; in that moment, he receives a letter from Renado, who asks him to return to Kakariko Village. Once there, Link receives instructions on how Ilia can recover her memory. From there, he must:


 * Obtain Renado's Letter from Renado explaining how to recover her memory.
 * Trade Renado's Letter with Telma in her bar for the Invoice, which illustrates the money owed to Telma by the town doctor, Borville.
 * Give the Invoice to Borville, which coerces him into revealing that Telma's cat, Louise must have stolen the Wooden Statue, the object of which Ilia experienced her first memory after being released from Bulblin captivity.
 * After transforming into wolf form, he must smell the scent of a medicine that was accidentally split near the Wooden Statue when it was stolen.
 * The medicine scent guides Link to Louise, who reveals that the Wooden Statue was stolen from her by a pack of Stalhounds.
 * After fighting the pack of Stalhounds in the field south of Hyrule Castle Town, they will give up the Wooden Statue.
 * Give the Wooden Statue to Ilia to retrieve part of her memory. Gor Coron, who began to accompain Renado since some time, recognizes the place where Ilia may have been during her abduction, then asks Darbus to unveil the entrance to that place so that Link can find clues on how to help Ilia recover her memory completely.
 * This place is found on Hyrule Field, ultimately revealed as the Hidden Village; here Link battles numerous enemies that are hidden in houses, behind barrels and boxes, and watching from high spots.
 * Impaz exits from her house after Link cleans up the area and tells him that she met Ilia, who gave her the Horse Call. Link receives this item, then goes back to Kakariko Village and shows the object to Ilia.
 * Ilia finally recover her memory and gives back Link the Horse Call as a reward (interestingly, Link was going to receive this item the day he was going to deliver the Ordon Sword in Hyrule Castle Town; in fact this is the item Ilia was making the day she asked her father, Bo, to allow everybody except Link to meet her inside her house, as the Horse Call was intended to be a surprise gift for him).
 * Although optional, Link can talk to Telma to make her know that Ilia is completely fine.

The game resumes the main quest from this point.
