Tu Perie Tperie is the first Light Bearer in The Tower's history, but how they came to be in that position is unknown. Whenever they reminisce about the time they became a Light Bearer, they're known to say, “The Heavens gave me the Eyes of God”. However, it could be that people choose to believe a “romanticised story” rather than the "exact truth".
After the Great Journey (Zahard and the Great Warriors conquering the Tower), Tu Perie Tperie became one of the most active Family Heads and is known to have created many items along with the Blacksmiths. They're also crucial in the pioneering of the system in which Light Bearers act as the intermediary for all communications within a team.
The most famous of Tu Perie Tperie's creations is the three "Opera" Lighthouses, among the greatest Lighthouses of The Tower. Tu Perie Tperie does not use the one they still possess however, preferring to use the Eyes of God instead.
Notes and Trivia
Considering the fact their feats indicate that they're very knowledgeable, perceptive, resourceful and innovative, they may have served as one of the strategists when Zahard and the 10 Great Warriors climbed the Tower.
Tu Perie Tperie is said to be male in the blogpost, although he has not been shown in the webtoon. This was confirmed by an original view of SIU's blogpost of Tu Perie Tperie and translated by AdiosCorea and Cletus.
