What you need are three blades of moonlight.
What you can find beyond the powers of the moonlight is where you need to go in order to find the Nightmare. What you need is a perfect blood gem. It must contain the power of the great ones. Will I, Sunset, be able to find a treasure like this one day? What I also need is the power of more than three umbilical cords for they harbors great insight.
There are 14 phrases one must keep in mind:
Grant us eyes
Guidance
Astro Clock Tower
Echoes of blood
Guidance
Moonside Lake
Guidance
Relic of the past
Flora
Beings of light
Lumenflower
Guidance
Relic of the past
Secret Garden
I'll engrave those words on the blade of moonlight. What is most important is "courage"; I must have the courage to destroy the blades of moonlight. As it shutters, the blades will absorb the umbilical cords and give birth to something utterly new.
Whatever is born will "awaken", it will show interest in the perfect blood gem...the gem will trust me and I will become its' "friend".
Lastly, I need the dream of a hunter.
Go there and wait for the blood moon.
That' when the Nightmare will come...
