Lidia (Korean: 리디아) is a thief who travels with a two-tailed cat named Ses. She fancies herself a treasure hunter like her father, and is searching the world over for magical artifacts. Her greatest wish is to find Alfheim, the hidden city of the elves, and acquire the one treasure (the treasure of Avariel in the original release) her father could never locate. She often refers to her Treasure Hunter Bible to figure out clues left behind by her father.
