After Erin discovered that the Princess was missing, she immediately raised an alarm, and the entire castle went into an uproar with Valkyries moving back and forth, searching for the Princess.
The entire castle was placed on lockdown almost instantly, and all the various checkpoints in the whole of Valhalla were blocked by powerful Valkyries. Erin knew that the Princess was powerful and had a lot of potential, but she didn't want to take any chances.
Not only had she blocked the exit points of the city, but Erin had also contacted the Adventurer's Guild situated at the heart of Valhalla. Unlike other kingdoms, Valhalla was a single city with about ten districts, each overseen by Valkyries referred to as district governors.
These districts didn't have any fancy names and were instead numbered from District One to Ten.
