Trazayuya Boruenan
An Elf from Boruenan Clan in Boruenan Forest that has broken through level 50 after devoting himself for 500 years, also called [Elf Sage]. He has a dream that someday elves will regain back the leadership of the world. He blamed himself for the death of several young elves under his care in the Selbira Labyrinth. As a result of the incident, he has been exiled from the forest. To atone himself, he created Maze of Trazayuya to be a safe training ground for future elves generation.

Touya
Touya was saved by Weasel Emperor, Tarou, when he was turning into a demon lord, probably because he overused his unique skill while creating the Maze. He then helped build the weaselkin empire as their [Tactician] because they offered him [Dungeon Seed] as a compensation. With his help, weasel empire advanced its civilization using science, that as a result violated God's Taboo and triggered Divine Punishment, destroying the empire.
