In Chapter 191, "The Plan of Relaxation", it is mentioned:

At the end of the Holy War that year, when the death toll of the Midalon people was counted, including Queen Sarah, Count Damon, Count Giraud, etc., about 100 people were missing, and the crystallized bodies could not be found.

In order to stabilize the hearts of the people, Emperor Eric concealed the news, and only claimed that more than 80 people were missing, but as for Queen Sarah, Count Damon, Count Giraud and others, they made fake crystallized bodies and placed them in the spiritual temple of the Midalon people in the divine domain. This is the inside story that only a few core figures know. Elder Heartless is also aware of this.

When I wrote chapter 219 "Why Sixteen Years", I found that this plot needed to be revised and changed to: "In order to stabilize the hearts of the people, Emperor Eric concealed the news and announced that only ninety-nine people were missing, but as for Queen Sarah, he made a fake crystallized body and placed it in the spiritual temple of the Midalon people in the divine domain. ”
