Reiss Chapel

The Reiss Chapel was a church in a village near the Reiss family estate. Above ground, it appeared to where the Reiss family would come to pray, but below the surface, it served as the site where the succession ritual for the Founding Titan took place.

Description
The Reiss Chapel was a small church to the east of Orvud District. Above ground, it looked and functioned like any other church. Below the altar, hidden by a rug, was a stairway that led to a large underground cavern. The cavern was created by the First King, and contained hardened crystal walls that produced their own natural illumination.

History
The cavern below the chapel was created over 100 years ago by the First King. Some time afterward, the chapel was built above it.

Throughout the last century, the Reiss family would gather inside the cavern in order to pass down the power of the Founding Titan every 13 years.

The Fall of Shiganshina arc
Shortly after the breach of Wall Maria, the entire Reiss family gathers in the chapel. Grisha Yeager finds his way down to the cavern beneath the chapel and begs Frieda Reiss to use the Founding Titan to save the lives of the people of the Walls. However, she refuses and Grisha destroys the chapel when he kills Frieda for her Titan and proceeds to slaughter the rest of the Reiss family. Only Rod Reiss escapes his family's massacre and he covers up the truth by claiming that the chapel was destroyed by bandits in an attempt to avoid suspicion.

The Uprising arc
Shortly after the resolution of the Wall Rose invasion, Rod Reiss has Kenny Ackerman's Anti-Personnel Control Squad kidnap his illegitimate daughter, Historia Reiss, and Eren Yeager and has them taken to the cave beneath the chapel. There, Rod has Eren chained in preparation for the inheritance of his Titan powers.

Dubious of the bandit cover-up story, Hange Zoë and the remaining members of the Special Operations Squad ride to the chapel in search of the captives. After finding the underground cave, the Survey Corps members ambush the Anti-Personnel Control Squad who had been guarding the area. Despite the MPs' advantage in numbers, the Survey Corps manage to drive back their opponents.

Rod attempts to coerce Historia into using a Titan injection and consuming Eren, regaining the Founding Titan for the Reiss family. Despite initially being receptive towards Rod, Historia has a change of heart and breaks the injection before throwing her father to the floor. As she begins unlocking Eren's chains, Rod Reiss licks the remnants of the Titan serum. Rod transforms into a massive 120m abnormal Titan that collapses the cave on itself.

Seeing the explosion from Rod's transformation, the Special Operations Squad moves further into the cave to find Eren and Historia. Reaching the succession altar, they free Eren from his chains, but cannot locate a safe exit due to the falling debris. Finding a bottle from Rod's bag labeled "Armor," Eren decides to believe in himself and ingests the serum. After transforming into a Titan, he hardens his Titan body, leaving a stone husk that prevents the cave from collapsing further. Squad Levi is then able to secure an exit from the cave.

The members of the Anti-Personnel Control Squad who had survived their battle with the Corps are killed by the falling debris. Only Kenny Ackerman makes it out, though he later succumbs to his wounds.

Later on, the shining stones in the cavern beneath the chapel are distributed to the population to provide a source of limitless light.
