Not to be confused with the Holy Mausoleum.

The Holy Tomb is a location in Fire Emblem: Three Houses and the setting of the battles in Chapter 11, Throne of Knowledge and Rhea's Paralogue, Eternal Guardian.

Overview[]

The Holy Tomb is one of the most sacred sites to the Church of Seiros. It is a large chamber deep underground beneath Garreg Mach Monastery. Its layout features a number of caskets that contain Crest Stones, as well as a throne overseeing the expanse. The Holy Tomb originates from the era in which the Nabateans and Agarthans fought, and is where Sothis slept to regain her power.

Once the goddess's power awakens in Byleth following their fight with Solon and brief banishment to Zahras, Rhea believes that Sothis will reawaken and return to the world once Byleth sits upon the throne within the Holy Tomb. She thus arranges for a special ceremony to take place, in which Byleth and their chosen house will serve as key participants. However, she does not realize that Sothis had already awakened within Byleth and subsequently merged her spirit with theirs. Thus, when Byleth sits upon the throne, nothing happens.

Before Rhea has an opportunity to question why the ceremony didn't yield her desired result, the Holy Tomb is invaded by the Flame Emperor and members of the Adrestian army. As the Adrestian troops begin to pillage Crest Stones from the caskets within the tomb, Rhea orders Byleth and their class to stop the Flame Emperor and recover as many of the Crest Stones as they can.

When the battle ends with the Flame Emperor's defeat, the mysterious figure is unmasked and revealed to be Edelgard. In the Azure Moon and Verdant Wind Routes, Edelgard will escape. If the player chose to teach the Black Eagles, and the prerequisites for unlocking the Crimson Flower route were met earlier in the game, Byleth will be given the choice to side with either the Church or Edelgard. Siding with the Church will open the Silver Snow route, and Edelgard will make her escape. If Byleth sides with Edelgard, the Crimson Flower route will begin. If the prerequisites to unlock the Crimson Flower route were not met, the game will continue on the Silver Snow route by default.

New Game+[]

During a New Game+, it is possible to unlock the ability to visit the Holy Tomb outside of battle by visiting the amiibo Gazebo on the Garreg Mach Monastery grounds and scanning a Fire Emblem amiibo. During such visits, the player can wander the space surrounding the throne and find rare item and ingredient spawns. While it is possible to look into the distance at the wider expanse of the tomb where the battles in Chapter 11 and in Rhea's Paralogue take place, the player cannot descend the stairs to explore. Depending on when in the game the player visits the Holy Tomb, they will either encounter Sothis or the opposite gender version of Byleth before the throne. The first time the player talks to either character, the Sothis Shield ability will be unlocked.
