Flaming sword

One of the enchantments used by swordsmen. It wreaths the blade in fire, using blood as a medium.

A pyromancy wielded by the unnamed captain of a forgotten order,
 who served a Lord of Light long since faded. 
It kindles an undying flame upon a weapon, 
using the caster's own blood as sustenance.

It is said that he was roused from death countless times, 
and each time, he ignited this very flame with his blood to confront the encroaching abyss.
