Solve the Riddle of the Sewers

==Walkthrough==
*Enter the Sewers beneath the Slums through a secret door by the gladiator prison in the Copper Coronet in the Athkatla Slums. At the eastern section of the area, you will find a room with drainpipes and a Glowing Pool, and a voice in your head will make known various cryptic remarks:
:"(The polluted pool takes on a faint glow. An excited voice resounds within your head.) At last! Find the keys, wielder! I've found a man lacking in worth, so he shall be my voice until I'm free."
:"Prove your worth and I shall submit to your mastery. Listen to the words of my jailor, who cast me off so that he might pass from this world:"
:"(The voice takes on a solemn tone.) Four locks are cast and made. Four wards will hold the blade. In what order shall thou place the keys? Four deaths await thee." 
:"(The voice resumes its excited manner.) "When all was silent, I crept from the slime and scratched rhymes for you. Vallah forbade it and hid me, but he is dead, so I've ignored him."
:"(The voice laughs.) I can't reveal all. Prove your worth—find Quallo. We shall speak through that vessel. Be careful! The wards must be broken in the proper order."
:"The voice laughs) Prove your worth—find Quallo. We shall speak through that vessel. Beware! Fail to break the wards in the proper order, and you must start again."
:"(The water glows, but the voice is silent. You notice words scratched into the rust of the four pipes that dominate the room.)"
*Click on each of the drainpipes in the room to receive hints for the four different items you must find, and the order the drains must be triggered.
*Stick your hands into the drain hole grating in the northwest corner of the sewers to find a Hand. Caution: Whoever does this will take damage. The area is guarded by an Otyugh and various slimes and oozes.
*Take the Lover's Ring off the hand of one of the skeletons near the center of the area.
*Near the center of the sewers you can find the Shaman's Staff in the possession of a Kobold Shaman. Defeat him or buy the staff from him.
*Go to the southern corner of the area and kill Quallo's friend, a Carrion Crawler. Take the blood from the body.
*Speak to Quallo and he will give you some hints regarding the strange unseen being inhabiting the drainpipe room, referred to as "the One". Quallo supplies information about what order the pipes must be interacted with to find out what may occur by resolving the riddle.
===Quallo's clues===
*About the hand: "It was Vallah's hand that cast the One into the depths. His suffering is of prime importance."
*About the ring: "It is not first, nor does belong in the third pipe."
*Quallo says nothing about the blood but turns away.
*About the staff: "The staff shall seal the bargain and prove your worth."
If the player is having trouble solving the riddle, see The Sewer Riddle solution page, separated to protect readers who don't want a "Spoiler". 
===Collecting the reward===
Upon interacting with the drainpipes in the correct order, the magical sword Lilarcor will be added to the inventory, and each party member will receive 18,000 quest experience points.
If you return to Quallo afterwards, he will remember nothing about your previous meetings and will declare himself to be free from his earlier possession.

The Alternatives mod adds content so that if you would like to avoid killing Quallo's "friend", you will see new options in Quallo's dialogue.
