Godslayer

The Godslayer (also known as the Pathfinder) is the main antagonist of the Pathless. He is a former human turned (almost?) god and the former leader of a cult that sought to find the One True Path. After acquiring the Sun Sword and the Spirit Mask he lost faith in his original goal, and instead decided to destroy the world and recreate it, building a perfect world for humanity with no uncertainty. This lead to him destroying the physical forms of all of the Tall Ones and cursing them to do his bidding in monstrous forms.

Personality
The Godslayer is shown to be ruthless, cruel, and intensely dedicated to his ideals. He is charismatic, able to convert people to his cause willingly. Even his enemies describe him as having an inherent magnetism. He is also just as willing to throw their lives away to brute force his way through problems. Despite this, he seems to genuinely care about finding the One True Path and bringing all of his followers with him into the perfect world he aims to create.

History
As a young man he was imprisoned for speaking out against the Tall Ones. While in prison, he amassed a large group of fellow prisoners and broke out with them. He was named the Pathfinder, the one who would find the One True Path and end life's uncertainty forever. They began to travel from one region to the next, gathering more followers and killing anyone who stood in their way. After forcing his way through the temple's puzzles, he acquired the Spirit Mask with the intention of seeing into the spirit realm and finding the path. To his terror, there was no Path. The Pathfinder decided that if there was no path, then he would make one. He took on the title of Godslayer and set out to kill every Tall One, end the world, and replace it with one of his own making. He broke into another temple, acquiring the Sun Sword. He then cursed every Tall One, turning them against their own worshippers and killing every person on the island. By the time the Hunter arrives on the island, everyone has died. The Godslayer sets every Tall One against her in an effort to dissuade her from her path, eventually cursing her directly. He is defeated on his floating island and dies at her hand.
