Desiree was a fourth-order Elf Sword Dancer.
She wore a thin sword at her waist.
Unlike the longswords and greatswords commonly used by knights, thin swords did not rely on strength but on skill to kill enemies.
However, not all thin sword users relied on swordsmanship techniques; a few relied on magic techniques.
The dance partner of a sword dancer was the natural elements.
Elf Sword Dancers used thin swords because the magical material, Betra Steel, used to forge the sword was too expensive, and even if forged into a greatsword, it would not enhance the sword dancer's combat power but instead make the elements harder to control.
Elf Elemental Sword Technique was a skill to control the power of nature. The raging elemental energies were bloodthirsty beasts rather than domesticated pets.
