Beyond the land of Tyria, Balthazar is engaged in an eternal struggle with his half-brother Menzies over control of the Fissure of Woe. It is not known who their parents are or if the other gods are related.
This inscription can be found on the Statue of Balthazar:
For weeks did the battle rage on, and those who had taken up the mantle of war grew weary and their courage began to falter.
Then did Balthazar, god of war and fire, appear to the soldiers, carrying with him a grand sword that did glow with such brilliance it blinded any who looked upon it. When he spoke, His voice was like thunder, and it shook the ground with force.
Then saith He, "Lift up thy weapons. For you are my soldiers, and must you be steadfast, strong, and brave of heart. They who neither hesitate nor stumble shall be rewarded. Then shall you have glory. Then shall your deeds be remembered for eternity."
And then did release from His sword a hundred thousand flames, which encircled the soldiers. For this was the fire of courage, and forthwith did they follow the god into battle without fear or hesitation. Thence was the enemy struck down.
