The name Soulcalibur is derived from the words soul ( from the title Soul Edge) and King Arthur’s legendary sword the Excalibur (eventually, the name would be utilised within the game’s world to represent the holy weapon which would counteract Soul Edge’s ultimate villain).
It revolves around a mystical sword of the legends, the Soul Edge that winds up in the hands of the dreadful pirate Cervantes de Leon of Spain.
He then sets forth a reign of terror in a little Spanish town whilst absorbing the souls of those who reached him during their search of the sword.
He is however soon defeated through the unified efforts of Greek divine warrior Sophitia Alexandra and Japanese ninja Taki with the use of one of the twin Soul Edge blades that is then shattered in the process.
As the sword was about to tear itself apart, a Prussian knight known as Siegfried Schtauffen approached the port town and battled Cervantes, whose corpse had been momentarily reanimated through Soul Edge’s will.
After emerging victorious, Siegfried’s attention turned unto the sword. The moment he took the hilt of the cursed blade, Soul Edge released a bright column of light into the sky.
This was known as the “Evil Seed”, bound to bring calamity and death in its wake.
Three years after those events, Soul Edge uses Siegfried as its host, and now Siegfried is Nightmare, a knight wearing azure armor and sporting a hideously deformed right arm. Europe plunges into a vortex of slaughters as he and his followers claim souls to strengthen the blade in its weakened state.
Unknown to them, a group of warriors met on their journey to stop Soul Edge, and with them, three sacred weapons join once again.
