Introduction

They signal their arrival with a devastating shriek, and leave nothing but ash, flame and destruction in their wake. All tremble in fear as they approach, and the ground rumbles in sympathy.

Word of an attack on the isle of Mos Le'Harmless has reached the ears of Sir Tiffy Cashien. Should you choose to accept his request, you will be sent to aid Sir Tendeth who has come across a great threat to the world; one far greater than the pirates he was originally sent to investigate.

Do you have the stomach to investigate this new threat, and see it through to the end? Or will you leave the world to its doom while you cower in fear?

Quest Walkthrough
1. Trouble in Mos Le Harmless

Unsuspecting victim

Items needed:

    * Amulet of catspeak (e)

To start this quest, you will need to speak to Sir Tiffy Cashien who is sat on a park bench in Falador park. He will tell you about an operative of his who is investigating a rather concerning issue on the island of Mos Le Harmless. Sir Tendeth - the operative that Sir Tiffy spoke about - is deep under cover in the Other Inn. Speak to him to find out more about his report.

As you speak to Sir Tendeth, something terrible happens. Go outside and ask the local pirates what happened. They'll tell you about various creatures that could have caused the damage to the village, but those you speak to agree that the creatures came from outside of the village. Head north and out of the border wall to investigate, Sir Tendeth will follow shortly after and meet his maker.

After dashing to safety behind a tall tree, you will need to head to the east to discover what killed Sir Tendeth. Use the tall grass and the trees that you find along the way as they will provide ample cover. Watch out for bushes near the trees as these will stop you getting into cover. It is strongly advised that you turn on run for this section, and do not stop unless you are directly behind a tree. If you get hit, the pirates will return you the the gates of their village.

You can use the route below, but any route through the northern half of the island will bring you to your destination, provided you keep in cover.
Path through the flame

When you reach the far side of the island, the cause of the damage to Mos Le Harmless and Sir Tendeth's fall is revealed. You should return to Sir Tiffy in Falador to tell him what you have discovered.
Archive note

Sir Tiffy will take you to the archive room where Lady Table will help you find out a bit more about Sir Tendeth's killers. In one of the archives there is a riddle which you will need to figure out.

The reincarnation part of the riddle is a cat - more specifically, it is Bob the cat - and the stonetoucher is you. Armed with these facts, you are sent to find Bob the cat and ask about his collar. Exit through the archive door when you are ready.

Bob is a traveller and never stays in one place for very long. In order to find him you will need to use an amulet of catspeak (e). If you do not have one, you can get an unenchanted amulet from the Sphinx in Sophanem. Make sure to have a cat or kitten following you at the time. To enchant it, take 5 death runes and your amulet to Hild in Burthorpe.

Open the amulet and move the compass points by clicking on the whiskers: left for anti-clockwise, right for clockwise. When Bob's direction is found, the amulet's eyes will glow white. Head in that direction until you find him.

Wear the amulet to speak to Bob when you have found him, and ask for his collar. You should study it to see if it can give you any further information. On the outside of the collar is printed, unsurprisingly, Bob's name but on the inside of the collar you will find the word DIRAKS. Given the contents of the note that you found in the archive room, you should realise that DIRAKS is the code to the plane of Kethsi. To use the code, you will need to head to the fairy ring in Zanaris.
2. To the Plane of Kethsi

Kethsi mural

Items needed:

    * Bob's collar

The code on Bob's collar must be input in two parts. Teleport to 'DIR' first, use the fairy ring to head back to Zanaris, then teleport to 'AKS' to find yourself within Kethsi.

Looking around - aside from the mural of the dragonkin destroying a city - there isn't much you can find from the area around the fairy ring. Given this, it seems logical that you should explore the rest of the area and see if there is anything that can help you find out more about the dragonkin.

From the fairy ring (A on the map), head up the fallen section of wall behind the mural (marked B). If you head north from there you will find a strange design on the wall. Investigating it you see a familiar pattern: something you have seen on Bob's collar.
Collar solution

Use Bob's collar on the wall design and line up the patterns. Bob's collar will fit the design as shown in the image to the right.

There will be a hidden compartment behind the wall; within it are several useful items. The 'note to you' will explain that Robert the Strong has hidden the items you will need to uncover the secrets of Kethsi within the ruins. He has given you two items that you will need - a tetrahedron and the arm for the statue.

You should return to the ground floor and search the area. There is rubble opposite the mural that will contain another tetrahedron.

When you have found the second tetrahedron, head back to the first floor and across the agility jump. Reattach the statue's missing arm and you will reveal a plank which will allow you to move across to the north-west side of the ruined building. Cross the plank and head down the ladder on the north side.

Ladders & wall jumps  Tetrahedrons

From the ladder (the red dot marked A on the map to the right) make your way across to the northern section of Kethsi using the various agility obstacles. After crawling through the tunnel and arriving at point B, you will need to mine your way through the rocks that stand in your way. If you do not have a pick in your inventory, there is one to your left.

After you have made your way through the rocks, continue though Kethsi using the agility obstacles. At the far west corner on the map to the right, head down the ladder to the ground floor and follow the path around to find another tetrahedron and a strange device hidden amongst the rubble.

From the tetrahedron head back to the building in the north-west and climb up both ladders (marked C). On the second floor, head across the agility obstacles (starting at D) until you get to the southern part of Kethsi. Here you'll find the final tetrahedron hidden under the rubble.
Kethsi grid references

With the final tetrahedron in your possession, head to point E where you will find stairs down to a basement. When you enter the room there will be a locked door in the south, a spade to the east and four indentations in the wall. If you do not have a spade, pick it up and then place your tetrahedrons into the indentations. Remember the letters you are given when you place a tetrahedron into the wall. You'll be given something like: 1 = E, 2 = H, 3 = A, 4 = C (EHAC).

Head back outside and use the strange device. It will give you a location such as BHDG - this is your current position. You need to find your way to the location given by the tetrahedrons. Given the examples match the codes you were given, you should use the spade to dig the ground at the position marked on the map with a white dot. If you are in the correct place, you will receive a Kethsian key - use this on the locked door back in the basement.

To your south there is a bookcase which, when searched, reveals Dathana's message. The message describes the Stone of Jas and the dragonkin, as well as a way of fighting them - bane ore. The bane ore tuning spell scroll can be found on the south-east bookshelf. Use it to learn the Tune Bane Ore Lunar spell. When you have learnt the spell, head back to Sir Tiffy to explain what you have found.
