The Sword of Mana is a special weapon that appears from time to time when a hero needs it to save the world.
This sword channels the energy of the Mana Goddess directly. Depending on who is wielding it, the sword can be a great tool of creation or destruction. It is inherently good, and will generally resist attempts by evil to use it, though it can be converted without too much trouble. In general, it only shows its true form under extreme circumstances, and usually appears to be a plain sword or even a rusty old blade.
Variance briefly wielded this blade and defeated a horrible monster, but was killed in the process.
