Background
The founder of Trazayuya Maze and the former proprietor of Ivy Mansion.

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.
