 [2.27] Treasure Hunting
=========================
     While exploring some Elven ruins, you came across a Human caught
     in a magical web. After you disarmed the trap and freed her, you
     learned that her name is Meraliss and she is an explorer from Ehb.

     Meraliss explained that the ruins are called the Vault of Therayne,
     and an ancient artifact is rumored to be hidden somewhere within.
     While looking for it, she became trapped and has been held in stasis
     for three hundred years.

     Though she has not found the treasure, she has no desire to continue
     exploring the place. If you want to continue and find the artifact,
     she'll reward you well.

Objectives:
* Explore the chambers behind the door.
* Release Treelus the Suffering from the magic binding him.
* Kill Treelus the Suffering.
* Return to Meraliss.

Welcome to, possibly, the most frustrating quest in Broken World. You'll 
stumble into this quest while poking your nose into an underground chamber in 
the Western Vai'lutra Forest. In the first room is a simple (Hah!) light 
puzzle surrounding a woman in a stasis field. The light puzzle consists of 
four columns, each with a light (currently lit) on top. Glowing lines of 
light connect the columns, like this:


  O-----O
  |     |
  |     |
  O-----O

When you click a column, the light reverses state and so do the lights that 
are connected. In this puzzle, click a column in one corner and both it and 
the columns in adjacent corners reverse state (going from on to off or off to 
on). To solve the puzzle and open the stasis field requires that all lights 
be off. This first puzzle is simple: click each column once (in any order).

The woman, Meraliss, is released from stasis and you can talk to her. She's a 
field agent for the F&K Society. She gives you a key into the next room, 
which leads to a more difficult puzzle. Once you solve that puzzle, you fight 
the monster (Treelus), get a Lore item from him and return to Meraliss to end 
this quest.

Killing Treelus also opens another door that leads to a third, more difficult 
puzzle, which, in turn, leads to a fourth. Solving the fourth puzzle gets you 
a small treasure chest with an Easter egg unique item. The third and fourth 
puzzles are not part of this quest, so you can finish the quest without 
finishing the puzzles. And the Easter egg item is useless.

Here are the solutions for the second, third and fourth puzzles. In each case, 
the columns are numbered from left to right, then top to bottom with the 
camera pointing due north. The solutions (along with the math required to do 
this on your own) come from here:
