According to Father Nobel's records, the Seven-Ring Sorcerer of the Pantanal Voodoo Society who used the "Arrow of Knowledge of Aikenora" over a decade ago was actually named Halder Undiba. He was a villager from "Lower Wood Village" in the Pantanal Swamp Region. Around the age of 16, he discovered his innate talent after being noticed by a pharmacist residing near his village and subsequently joined the Voodoo Society.
This Seven-Ring Sorcerer was eventually ambushed and killed by the church in Rust Alley, western Huntington City, after a fierce battle. Even after his death, the church scoured both Rust Alley and his birth village, but they were unable to find the "Arrow of Knowledge of Aikenora."
The last use of the arrow was three days before Undiba was ambushed by the church, and during the final confrontation with the church, the arrow was not used.
