DESCRIPTION:
"Obey me mortal or feel my wrath." - Elysium (SCV)

Elysium is the entity that guides the wielder of the Soul Calibur, "born" from the purification ritual that created Soul Calibur. The ritual was flawed due to Algol's lust for power, giving rise to a will that was similar in nature to Soul Edge's own. The tribe assigned to guard Soul Calibur recognized this and sealed the sword's will away, implementing rules to safeguard against the possibility that Soul Calibur's similarities to Soul Edge ran deeper than reading its wielder's soul and shapeshifting. Millennia later, the clash between Soul Edge - wielded by Nightmare - and Soul Calibur - wielded by Siegfried - broke the seal placed on Elysium. Choosing Siegfried as her host due to their mutual hatred for Soul Edge and his desire for redemption making him an easy pawn, she covered his body in crystal armor to protect and heal him. After Nightmare was slain and Soul Edge shattered, Elysium awaited the cursed sword's inevitable return. Siegfried's growing suspicions of Soul Calibur made her deem him unworthy as a host, so she changed her form and awaited a new host she could manipulate.

I do not own this game or the soundtrack. That stuff belongs to Namco.
