Just as it says above, I need a prophecy (a friend of mine  gave me an idea, but I like to have more options) plus a big bad (even if I have one in mind I like to have more options for the story.) So if you guys have any ideas for either one then please comment. 

I will just say this though, the Sword of Promised Victory: Excalibur must be a part of the prophecy. As well as the Hound of Ireland. 

Anyways, thank you for reading this and I hope you have a good day!

Edit:

Here are the prophecies that I came up with but I am having trouble with coming with one that would fit the story. Whichever one has the most votes I will use. Thank you.

1) The favored son of Ireland

Along with humanity's strongest steel that was hidden by the moon

Shall head west to find the lost thunder,

Time shall hide with the shadows

And bring forth the bloody war to face the hound of Ireland and Alaya's blade

To be slain or save they must pull forth the memory of the promised victory

2) Heroes of Crimson and Azure stand together

To find the promised golden sword

To prevent a big disaster

As they fought against the horde

their efforts are myths but not a miss

Encountering various stories from all over the globe

Before the world explodes

3) With the past unraveling,

Three heroes gather,

The King, the Hound, and Humanity's Guardian,

To fight a force of power never seen before,

As the World's Evil's is Released,

The Memory of Promised Victory is unleashed

In a World of Unlimited Blades,

Evil engages combat with Seven.

Version two of #3) When Darkness rises,

Three Heroes gather and four more rise.

To fight an unknown enemy hidden by the Gods.

Corrupting the minds of all who hears him,

He will bring upon the world's demise.

Unite all seven Heroes, one less will doom them all.

One more, will tilt the scale of good and evil.

4) Ghosts of past lives meet again,

The Hero, the king, the hound, find a way

To the sword of promised victory

A beacon of hope

Lest the world descend to darkness
