Biography: The nation of Aethra was once a theocracy, and the Grand Church oversaw all. Every city was bound by their laws, and the most important law of all was that you Believed.
Those that did not Believe were given the opportunity to Repent, which involved granting all their property to the church. Most agreed readily, considering the alternative was being tied to a stake and then set on fire.
But there were a few who refused to Repent, or agreed to Repent and then went on to Blaspheme once they thought the Church was out of earshot. (It never was.) And these Blasphemers were burned, prominently and publicly, to inspire others to Believe.
Yet there was one Blasphemer who continued to decry the Church even as their body burned on the stake. The flames burned harder and harder, and the Church's men added more kindling, poked the body with swords and spears, yet the Blasphemer's voice would not stop. Indeed, it grew louder with every moment.
Then the fires started raging out of control. The inquisitors tried to douse the flames, but no amound of water seemed to slow the inferno. And the voice continued shouting, continued to curse the Church for its crimes.
The flames engulfed one of the inquisitors, and as he burned in agony, the Blasphemer named those who had died by his hands, one by one. And the flames continued to spread.
By morning, every inquisitor had burned to death. There was no sign of the stake the Blasphemer had been tied to, nor of the flames themselves.
The next night, the Grand Church in Aethra's capital burned to the ground. In a panic, the blasphemy laws were overturned and the church disbanded. There would be no more Blasphemers.
None knew what had happened to the last one. There was not even any record of who they had been.

Description: The most prominent feature of the Final Blasphemer is that they are on fire.
Indeed, the fire is all that can really be seen. There's a large wooden post in the center of it all, and if you squint you can see the silhouette of a human in there, but it's impossible to make out any identifying features.
In fact, it would be easy to believe there was no one in the flames at all if not for the voice. The voice screams about corruption and hypocrisy, in very specific terms. It seems to adjust its speech to relate to the government of whatever area it's currently in.
It also doesn't seem to like any sort of organized religion. This is not really all that surprising.

Weapons and Abilities: The Final Blasphemer's main ability is being on fire. This has fairly obvious implications.
It also appears to have complete knowledge of the actions of anyone in its vicinity. If someone is near the Blasphemer and it deems them to be good of heart, it will use its flames to protect them. If it deems them to be wicked, it will burn them and call out their crimes one by one.
It is naturally drawn to what it considers "agents of sin", mostly those most complicit in the crimes of whatever government or religion it's complaining about. It seems to have an inherent knowledge of the local political systems, as it usually starts screaming about specific scandals within moments of crossing a national border.
