Moonlight Fiend

You begin the quest at night in Comodo, with the Night's Shade (296,238).

Nighttime is shown with @time
You need a minimum Job Level of 30

If you talk to the Night's Shade at night, you get teleported to the realm of the Moon Spirit.

Moon Spirit immediately tells you what she needs.

        "Child with potential. Small light in earthy darkness. Coal smell. Bring it."

Coal smell hints at somewhere with a lot of Coal. Earthy Darkness means it's probably underground.
Only option is seems to be Coal Mines.
The only item that mentions light is Lantern from Skeleton Workers.
Once the chat ends, she teleports you back to the Night's Shade.

Return to the Moon Spirit with a Lantern.

She gives us another riddle.

        "Extinguished? Find new light. Liquid light. Captures sunlight. Bring it."

Return to the Moon Spirit with [Requested item]

She gives us another task.

        "Final task. Find the sun. Desert, cold nights. High point, near smoking stone. West of a revered goddess' temple.
        I see the Sun there. Put liquid in lantern. Hold it high. In the light."

We are also given an item called "Fluorescent Lantern".

Go to the location as described in the riddle.

Look for a NPC called "Blinding Light"
Careful, you'll suddenly get 1000 additional weight in your inventory when you finish this step.

Return to the Moon Spirit.

She's happy and tells you to get your reward from the Night's Shade.
However, Night's Shade cannot give you the reward without some help.

        "Your reward? I can give it to you, but I need a catalyst. A life that blossoms only in moonlight."
        "Normans rarely see this life. Like a mirage, it sometimes plays tricks on your mind."
        "Women who drown lovers in forest rivers carry these things."

There are 4 ways of obtaining the required item.
