Quest 1: Prologue

Quest 01: Prologue is a tutorial quest in Kingdom Hearts Union χ. The quest teaches basic combat skills.

The quest begins with Kairi's Grandma telling Kairi a rendition of The Legend of the Light. She concludes her story as Player begins their Dive to the Heart where they must choose their Union. After choosing, Player's Station is swallowed by Darkness. They summon the Starlight Keyblade and the darkness recedes.

Player then arrives in Daybreak Town where they meet Chirithy who explains that you are a Keyblade wielder chosen due to your pursuit of light, that darkness is spreading, and that it is your job to stop it.
