Five of the many remnants of Sanctus Nightmare, left behind before he was banished to the Void, are his Five Swords of Death, five legendary blades with infinitely powerful properties. Inside each blade is a hidden power to them that maximizes their abilities. However, how to tap into this power is unknown, and each sword seems to require a different method to do so.

Alongside the many other remnants, these swords have changed the entirety of history for the worst. They have been the origins of war, famine, disease, and death. To any who seek these weapons out, be warned, for even a slight taint in one's mind, body, or soul could spell disaster on an infinite scale.

Glacadh An Bháis

Otherwise known as the Olc Sword, this sword was the first one that Sanctus Nightmare designed. It is indestructible, unable to rust, dull, or be altered in any fashion. Tapping into it's power give the sword infinite density, allowing it to shatter through any other blade with sheer durability. It was left behind in a volcano to preserve it for centuries. In terms of endurance, this blade is inevitable to succeed.

Margáil Le Bás

While not as strong as the others, this sword makes up with it with its shapeshifting capabilities. Tapping into the sword's power, the user can extend the length of the blade to an infinite length and alter its form. The blade will still retain its sharpness upon changing forms.

It was left behind in a cult church in an altered, disguised state by Sanctus Nightmare and later found by Prince Doúlos Thanatus.

Fearg Ó Bhás

Crafted from Sanctus Nightmare's passion and fury, this sword's power is maddening. It can cut through most anything, and tapping into its true power gives it infinite cutting power. It can cut through anything with no effort, but it is unknown if it can damage Glacadh An Bháis.

It was thrown into a powerful storm, said to never die out beyond the lands of the known world, by one of Sanctus Nightmare's followers.

A Sprioc Amháin

Sanctus Nightmare's claimed favourite blade, this sword has an infinite capacity of applying pain and suffering.

While it doesn't cut as deep or bear much weight or length to it, upon making contact with blade, the victim is instantly struct with an immeasurable amount of everlasting pain. Tapping into its power prevents the pain, which dwarfs the travel into the Scorpionfloor Temple at the center of the Jungle of Agony to obtain it.

Ag Séanadh Marbh

The final sword that Sanctus Nightmare created, this sword defies order and logic of the physical world to an a infinite degree. It can stab a target behind the user with a forward stab, it can chop in two directions whilst being still, it is unpredictable and dangerous to all in whatever distance the sword seems to want. Only Sanctus Nightmare himself and a few select others have been known to use it effectively.

Where it rests is... unknown. Even in plain sight, the sword can disappear. By tapping into its true power can the user properly control it.
