A traveler has fallen on the Saka Plain in the easternmost realm of Elebe, and an orphaned young woman named Lin comes to the traveler's aid. After she nurses the traveler back to health, the two embark on a journey to hone their respective skills at swordplay and battle strategy. Shortly after their journey begins, Lin must confront an unexpected destiny. She learns she is heir to the throne of the neighboring Rikea and becomes entangled in the struggle for succession. Once this news is known, knights come to serve her while assassins come to take her life. Being a well-schooled military strategist, the traveler she rescued reciprocates by coming to her aid and vowing to return her safely to Rikea, her grandfather's homeland.
