* The Echo of the Universe
The echo of the universe is a manifestation of the will of the world itself, by its will incomprehensible to ordinary people, the chosen of the masses awaken, becoming resonators.
*Resonators
Resonators are people who have been awakened by the will of the Echo. Each of them has special abilities acquired after awakening, in order to destroy monsters crawling out of the gate, as well as to protect humanity.
* The Gate
Gates are magical portals created from more mana. When a large number of monsters gather together, the pack leader collects a huge amount of mana to break through the barrier, forming a gateway to another continent.
Monsters sense mana flows and find "weak spots" in the barrier.
To prevent the formation of gates, the resonators had to make landings on another continent to prevent the gates.
* Nifrael
When studying the remnants of culture by scientists and archaeologists, the name of the formed continent, Nifrael, was approved.
*Castle
Castles located on Nifrael serve as fortresses guarding portals. It serves as a strategic target and shelter for resonators during sorties.
*Fragment
A fragment that defines the specialization of the resonator's ability. Bestowing unique magical abilities on the wearer.
*The line

*Mana Core

* Clumps of darkness
The cores are in the monster's body, but unlike the normal mana core, it is tainted with infected mana.
*Ranks

· Resonator
· The Awakened One

A feat that will be recognized by the world, it can be different for everyone depending on the resonator and his abilities.
