In the winter military training of the Baron Keane Hill, an interesting thing occurred.
At the time of the second military training, a large group of farmers were lined up in the grain-filled ground and worked hard to practice the thrusting techniques under the guidance of the junior officer. Suddenly, the sentinel who was responsible for standing guard at the village watchtower screamed and rang the alarm bell.
Every village or town's watchtower had an alarm bell, and once the sentinel found an emergency, he would ring the bell. When he rang the bell, the elderly, the weak, women and children should hide as soon as possible, and the young and strong must gather immediately, trying to resist the threat.
This was the common practice in every place of the Main Plane, so various settled races were similar in practice.
