Sealed Monsters

Throughout Raphtalia's World, there are several burial mounds which contain monsters which have been sealed away in the distant past. Using the right magic, it is possible to unseal these monsters and unleash them upon the world.

Overview
Throughout history, various monsters had run amok throughout the world. Thanks to the efforts of several heroes, pacifiers, and adventurers, these monsters were able to be magically sealed in an extra-dimensional space. These monsters were sealed instead of killed because sealing powerful monsters somehow helps repel the waves. However, these beasts can also be unsealed and unleashed upon the world. This can be done through magically breaking the seal. According to well-travelled adventurers, there are several burial mounds spread throughout Raphtalia's World.

The burial mounds in Q'ten Lo have a slightly different purpose than the ones outside. Instead of powering the barrier which protects the world from the waves of calamity, these burial mounds power the barrier which surrounds Q'ten Lo. This Q'ten Lo barrier prevents reincarnated individuals or Heroes entering without permission. Raphtalia's Ancestor is a pacifier from Q'ten Lo and is responsible for many of the sealed beast in Q'ten Lo, Siltvelt and around the world.

Tyrant Dragon Rex
The Tyrant Dragon Rex is a dinosaur-like dragon which possesses a dragon emperor fragment which had corrupted and warped the creature. It is unknown who had originally sealed it but the burial mound had been protected by the Rabier family until Idol Rabier unsealed it to enact his revenge against Naofumi and his party. The group were narrowly saved by Fitoria who had easily killed the monster.

Tulina
Tulina is a nine-tailed fox monster who had originally come from Q'ten Lo. Many years ago, she had charmed the four elite races of Siltvelt and tried to take control of the nation. However, she was stopped and sealed in Siltvelt by Raphtalia's Ancestor who had chased after her. It is unknown how she became unsealed - either by her force or some external force - but she became unsealed around the time Naofumi and the other Heroes were summoned. She then joined Takt in his conquest to take over the world.

During Takt's conquest, Raph-chan II (who was the reincarnation of Raphtalia's Ancestor) fought against Tulina. Together with Raph-chan, they killed her.

Yamata no Orochi
The Yamata no Orochi, or "Sealed Orochi" is a powerful beast with a dragon emperor core in the form of a cursed sword. The orochi has eight heads which can regenerate at incredible speed. The orochi is able of generating an incredibly hard barrier and using Way of the Dragon Vein to corrupt the surrounding earth. Each head can do a breath attack including poison, fire and ice attacks. Finally, this orochi can make a less-powerful clone of itself to fight on its behalf. This beast can only defeated by destroying all eight heads at the same time and then destroying the body.

This beast was blessed and unleashed by Makina who was trying to eliminate the threat of Raphtalia from taking the Q'ten Lo throne. However, it was defeated by Naofumi and his party.

Other Sealed Beasts
Several other sealed monsters were unleashed by Makina to defeat Naofumi and his party. However, they were able to defeat them all. They all had a cursed weapon in their core which includes some claws, a spear, and an axe. Unsealing these beasts likely diminished the power of the barrier surrounding Q'ten Lo.

Guardian Beasts
Guardian Beasts can technically be called sealed monsters, however their function is slightly different from the others. Instead of providing protection when sealed, Guardian Beasts act as like a backup which can be unsealed if the Heroes are not performing their duties. However, their help comes at a heavy cost since Two-thirds of the global population must be killed in order to permanently defend the world against the waves.
