The King of Shadows looms over all, but no obstacle is insurmountable. No foe is immortal. You only need the right circumstances. The right tools.
The right weapon.
I did promise you a gift, didn't I? This is its nature. It's a weapon of heroes that was built to battle the shadow - wielded by few and forged by one. Its smith's soul may have faded, but his legacy is yours to carry on, so long as you can claim it.
However, I have made one slight alteration. When it was first conceived, it took four sets of hands to wield this weapon properly. Now a single pilot can use it with ease - one warrior controlling the power of four souls.
Look for my sign, and I can give you the keys to its construction. Yet take care in gathering them. The shadows can sense my influence upon them, and that will draw peril to their side, as it always has. So fight as heroes did, and should you succeed, their strength will be yours. Theirs, yours and mine. Together. As one.
