@cya@Walkthrough:
@whi@Begin by speaking to @yel@King Lathas @whi@in Ardougne Castle. Exit the castle and go through the @cya@Gateway @whi@into West Ardougne. Make your way to the far north-west corner of west Ardougne, past the @cya@Gravestones @whi@and @yel@Zombies@whi@. Talk to @yel@Koftik @whi@and enter the @cya@Cave@whi@. @whi@The immediate @whi@path to the west is blocked by a swamp. @whi@There is a path to the north that bypasses the swamp. Climb over the @cya@Rocks @whi@and climb the @cya@ledges @whi@to make your way to @yel@Koftik@whi@. Speak to @yel@Koftik @whi@and he will give you a @lre@Damp @lre@cloth@whi@. use the @lre@Damp cloth @whi@on an @lre@arrow@whi@, then light it on the @cya@fire @whi@nearby. Climb over the @cya@Rocks @whi@and up the @cya@Ledge @whi@to the north to get a better view of the @cya@Old bridge@whi@, then use the @lre@Lit arrow @whi@on the @cya@Old bridge@whi@. The @cya@Old Bridge @whi@will fall @whi@and you'll automatically @whi@cross to the other side. Mine the nearby @cya@Rock @whi@to break @whi@off some @lre@Rocks@whi@, then continue further down the path (to the south-east) until you come to another @cya@swamp@whi@. Use the @lre@rocks @whi@on the @cya@swamp @whi@to create a path across. if you accidentally click the option "step over" the @cya@swamp@whi@, you will be washed away and tumble down a chasm and have to climb over the @cya@Rocks @whi@to get out. After passing the @cya@swamp @whi@you'll come to a @cya@pit of spikes@whi@. @whi@Use your @lre@rope @whi@on the @cya@Stalacite @whi@to swing across.

@whi@Go past the @yel@Giant bats @whi@and you'll come to a tile puzzle with 25 @cya@grills@whi@. There is some @lre@cookedmeat @whi@nearby if you want to heal a bit. the solution to the puzzle is as follows:
Row 1: Fourth tile from the south, Row 2: Third tile from the south, Row 3: Third tile from the south, Row 4: Second tile from the south, Row 5: First tile from the south. Pull the @cya@lever @whi@at the end and search the @cya@Rocks @whi@to disarm the traps. You'll come to a room with @yel@Zombies @whi@ and a @cya@furnace@whi@. Continue west, being sure to search the @cya@Rocks @whi@to disarm the traps.

@whi@You'll come to a room with an @cya@Alter @whi@and a @cya@well@whi@. From here there are four paths, each of lead to an @lre@Orb of light@whi@. Grab the @lre@Journal @whi@on the ground if you want to read about the @lre@orbs@whi@.

@whi@North Passage: Pick up two of the nearby @lre@planks @whi@and go north to the @cya@passage@whi@. Use a @lre@Plank @whi@ on the @cya@Passage @whi@to safely cross it and grab the @lre@Orb of light @whi@then use your plank to get back.

@whi@North-West Passage: Go past the @yel@Rats @whi@and @yel@Ogres@whi@. Pick up the pink @lre@Orb of light @whi@and return to the main room.

@whi@West Passage: Disarm each trap and pick up the blue @lre@Orb of light @whi@at the end. If you fail to disarm one of the traps, you will trigger all of the previous traps and take damage from each. Be sure you have more than about 20 hits when trying to disarm the traps near the end. Disarm each trap to return.

@whi@South-West Passage: Use one of your @lre@Ropes @whi@on the @cya@Stalagmite @whi@and your character will tie the other end around their waist. Walk down the Passage and it will fall out from under you. The @lre@Rope @whi@will save you from falling into the spikes. Grab the yellow @lre@Orb of light @whi@and climb up the @cya@rope @whi@to escape.

@whi@you can search the @cya@Stalagmite @whi@after this and retrieve your @lre@Rope @whi@back.

@whi@Go east and return to the room with the @yel@Zombies @whi@and the @cya@Furnace@whi@. Use each @lre@Orb of light @whi@on the @cya@Furnace@whi@. Then head back west, back to the room with the @cya@well @whi@ and the @cya@Alter@whi@. If you have at least 50 Thieving, grab a @lre@plank @whi@for a short-cut in the following segment. Enter the @cya@well @whi@and talk to @yel@Koftik@whi@. The @cya@Crate @whi@nearby contains 2 @lre@salmon @whi@And 2 @lre@Meat @lre@pies@whi@, if you need to heal. It can't be opened twice, even if you log out or leave the area, so make the most of the food. if you need a @lre@Rope @whi@there is one at the end of the path to the south.

Continue west and you'll come to a room with @yel@Goblins @whi@and four prisons with @yel@slaves@whi@. The north-eastern cell has some @cya@Dug up soil@whi@. pick lock the @cya@Railings @whi@then search the @cya@soil @whi@to find a @cya@Tunnel@whi@. Enter the @cya@Tunnel@whi@, then go west and you'll come to a @cya@Wall grill @whi@that is too high for you to climb. Use a @lre@Rope @whi@on the @cya@grill @whi@and you'll be able to climb over it.

Immediately to the east is a pathway with lots of @yel@Giant bats @whi@and @cya@Rocks @whi@to climb over. if you have at least 50 thieving, you can take the southern path that bypasses the agility obstacles by picking the @cya@fence @whi@(be sure to use a @lre@Plank @whi@on the @cya@passage @whi@at the end). Otherwise, go east and make your way past all of the @yel@bats @whi@and @cya@Rocks@whi@. if you fall, Climb up the nearby @cya@Pile of mud @whi@to return to the start. At the end, both paths meet up near a room with a @lre@Worm hole @whi@which heals 12 hits. If you have 50 Thieving you can enter the room and pick it up. Continue West and climb up the @cya@ledge @whi@to enter a room with @yel@Skeletons @whi@and a @yel@unicorn@whi@.

@whi@Search the @cya@Railing @whi@of the @cya@Unicorn's @cya@cage @whi@to get a @lre@Piece of @lre@railing@whi@. Go south-east of the @cya@Unicorn's Cage @whi@and climb up the @cya@ledge@whi@. Go east and use the @lre@Railing @whi@on the larger @cya@Boulder@whi@. it will fall off the edge and crush the @yel@unicorn@whi@. Return to the @cya@Unicorns cage @whi@and search it to get the @lre@unicorn horn@whi@, then climb up the @cya@ledge @whi@to the west.

@whi@Talk to @yel@Koftik@whi@, Then pick the @cya@railing @whi@to the east. Make your way past the @yel@Zombies @whi@and @yel@UndeadOnes@whi@, then pick the @cya@Railings @whi@to enter the room with the three @yel@Paladins@whi@. Kill all 3 @yel@Paladins @whi@and pick up 3 @lre@Coat of @lre@arms@whi@. Go west and search the @cya@Rocks @whi@to disarm the trap. You'll come to a large @cya@Cauldron @whi@called @cya@Flames of zamorak@whi@. Use each @lre@Coat of arms @whi@on the @cya@cauldron@whi@, then use the @lre@Unicorn horn @whi@on the @cya@Cauldron@whi@. Open the @cya@Gate of Iban @whi@to the west and you'll be in a large open area.

@whi@Make your way onto the @cya@platforms @whi@and go far south, if at any time you fail one of the Agility obstacles and fall to the area below, you can climb back up by going to the @cya@Mud pile @whi@at the north-west corner. You'll come across @yel@Kardia the witch@whi@'s House. Ignore it for now, and continue south to the @cya@Stone steps@whi@. Walk down the @cya@steps @whi@and go west to the to the @yel@Dwarves' @whi@camp. talk to each @yel@Dwarf@whi@, then go back up the @cya@Ladder @whi@where you came down.

@whi@Go back to @yel@Kardia the witch@whi@'s house and go to the @cya@platforms @whi@to the north-west to find her @lre@cat@whi@. It may help to check for a red dot on the mini-map. Return to @yel@Kardia The Witch@whi@'s house, don't try to open the @cya@door@whi@, use her @lre@cat @whi@with the @cya@door@whi@. After @yel@Kardia @whi@takes her @lre@cat@whi@, open the @cya@door @whi@and take the @lre@Doll of Iban @whi@from the @cya@Chest@whi@.

@whi@Go west from @yel@Kardia The Witch@whi@'s House and kill the 3 demons: @yel@Othainian@whi@, @yel@Doomion@whi@, and @yel@Holthion@whi@, Each Demon should drop an @lre@Amulet@whi@. if they only drop @lre@Ashes@whi@. you may need to talk with the @yel@Dwarves @whi@again. Once you have all 3 @lre@Amulets@whi@, open the @cya@Chest @whi@to get @lre@Iban's Shadow@whi@. Use @lre@Iban's @lre@Shadow @whi@on the @lre@Doll of Iban@whi@.

@whi@Make your way south-east to the @cya@stone Steps @whi@and return to the @yel@Dwarf @whi@camp. Talk to @yel@Klank @whi@and he will give you a @lre@tinderbox @whi@and @lre@Klank's Gauntlets@whi@. pick up the nearby @lre@bucket @whi@and click "empty" on the @cya@barrell @whi@in the building to get some of the @lre@dwarf @lre@brew@whi@. Go east and find the @cya@Tomb of @cya@Iban@whi@. pour the @lre@brew @whi@on the @cya@tomb@whi@, then light it using your @lre@tinderbox@whi@. It will burn and reveal @lre@Iban's @lre@Ashes@whi@.
