Character Cards are often rewarded by specific NPCs (often known as UPCs) throughout Granado Espada, granting you the ability to create that character as one of your own family members. In order to add them to your family, these UPCs will ask you to complete a series of quests. Some of these quests are more difficult than others. Most Character Cards are tradeable, meaning you can buy them on the Market or trade directly with other players.
