A map of the areas that are accessible in Kethsi

Kethsi is a planet near the Aviansie homeworld of Abbinah, and which once housed a prosperous civilisation. At some point in history, their Conclave of Elders found the Stone of Jas through the World Gate and the Kethsians used it to greatly boost their success in all fields. However, this equally empowered the Stone's guardians, the Dragonkin, and these soon arrived to Kethsi. The dragonkin destroyed the entire realm completely, wiping out the Kethsian civilisation and killing all inhabitants. Kethsi remains dead and ruined to this day, and ash still falls from the sky.

Kethsi may be accessed only via the fairy ring system using the code DIR immediately followed by AKS. This is currently the only method in and out of Kethsi as the World Gate once used by its inhabitants to travel between planes no longer exists.

Kethsi features heavily in the quest Ritual of the Mahjarrat as the history of the Stone of Jas and the dragonkin are revealed by exploring Kethsi during the quest. The only part of Kethsi which is currently accessible is the Isle of Sann and Mount Firewake.

History

Kethsi was a large, advanced civilization of an unknown age which was mainly inhabited by a Mage Conclave. Late in the summer of the Year of the Babbootang, the Stone of Jas was brought to Kethsi by Elder Mage Etheron after a six-year expedition. The inhabitants of the plane relocated the Stone to the Mage Conclave on Mount Firewake.

The act of bringing the Stone of Jas to the Kethsian plane through the worldgate brought great prosperity to all Kethsians. The inhabitants were able to tap into the power of the Stone in order to work various spells which improved the living conditions of Kethsians and helped repel any enemies. However, prolonged use of the Stone of Jas provoked the dragonkin, leading to the invasion of Kethsi from the east by dragonkin.

The conclave gathered 52 Grand High Mages to fight against the dragonkin, but their most powerful spell backfired and only succeeded in further enraging the assailants. Continued attempts to combat the dragonkin were made, all to no avail. It soon became evident that trying to fend off the dragonkin with the Stone of Jas had no effect as the Stone's power was directly linked to the dragonkin themselves. Renowned philosophers of Kethsi remarked that the dragonkin only appeared after the Stone of Jas was brought to Kethsi. They further speculated that the dragonkin may therefore be some sort of guardians of the Stone, used to prevent unworthy beings from accessing its power.

The efforts of the Kethsians were futile, and soon the headquarters of the Conclave were destroyed. A small remainder of the surviving Kethsians retreated to the Isle of Sann in the hopes of escaping the dragonkin.

In a final effort to stop the dragonkin, attempts were made to create a weapon using bane ore. Weapons made from bane ore may be magically "tuned" to be harmful to certain creatures. Smelting the ore and using the bars on the tempered anvil located on the Isle creates bane bolts and arrows, proven to be able to take down dragonkin. However, the supplies needed to mass produce such weapons were not available, and it is assumed that the dragonkin were eventually able to destroy Kethsi, resulting in its present condition.

The events leading up to the attack on Kethsi and the attack itself are chronicled by Dathana in a message left behind on the Isle of Sann.

Isle of Sann

Entrance hall

The only entrance or exit to Kethsi is a Fairy ring located to the very south-east corner of the area. Just north of it, there are some ruins, with a wall in the middle with a mural on it. It shows dragonkin, as you can see by the legs and feet, destroying a city. It is unknown whether this has been drawn on the wall before or after Kethsi was destroyed, which makes it impossible to know whether the mural is about the Isle of Sann or another city.

On the opposite side of the mural is some rubble, and upon searching it a Tetrahedron 4 can be found and is used to gain the coordinates to find a key used in Ritual of the Mahjarrat.

First floor

The map of the first floor.

The wall design.

On the first floor to the north, a wall design can be seen. When investigated, it shows four different columns which do not seem to fit together without intermediate pieces. One of the symbols on the columns look like an upside-down Dorgeshuun goblin insignia. There is a statue next to the wall design, which when examined says "It doesn't look like it's meant to be human."

At the southernmost part of the first floor there is a ledge which can be jumped across at level 77 Agility. This will reward 2xp in Agility. Players must have 77 Agility and it cannot be boosted. To the other side of the ledge is another statue, similar to the one at the first side of the ledge, but with its left arm missing. A little to the north, there is a wooden plank which seems to partially cut through at height of the first floor's ground. During the quest Ritual of the Majharrat, this plank is knocked down to gain access across the gap to the anvil to the north.

To the north of this separated area, behind the plank, is a small platform with a "Kethsian anvil", with the examine "I may be able to make Kethsian items on it.". This anvil is in fact used after the Ritual of the Majharrat to fashion items made from bane ore.

Further areas

The underground library

To the west of the rope swing there is another anvil looking identical to the Unusual anvil on the first floor of the main hall. A fairly long distance to the west is another building of two floors high, with two ladders in it. There are parts of a ledge and hand grips at this building. South of this building is another which is also two floors high. South of this is a staircase which goes underground, and south of that is a ledge leading to a small island which is empty other than some ruins, a tree and another searchable rubble containing the second tetrahedron.

Kethsi

Postbag from the Hedge

A map of the coordinates shown in the postbag.

On 7 October 2010, the 44th Postbag from the Hedge was released, including hints for Herblore Habitat and Do No Evil. However, the journal included a final hint which read:

Fourth Age, year 2212N1145E

Origins lie in ruined Kethsi, but now they return from the stone prison to lay waste .? The strong remembers, the weak falls.

The year provided in the journal shares the same format as coordinates used in Gielinor. When treated as a coordinate, "2212N1145E" leads to a point just west of Zemouregal's fort which is located just adjacent to the Wilderness. "The strong" in the post, a singular noun, is a reference to Robert the Strong, a hero from the Fourth Age who fought against the dragonkin. Robert succeeds in imprisoning the dragonkin, but it is revealed in a note that he leaves behind in Kethsi that he was aware of his impending reincarnation as Bob the Jagex Cat. Additionally, in the epilogue of While Guthix Sleeps, the dragonkin reveal that their anger is escalating due to the increased use of the Stone of Jas, heightening their desire to lay waste to the world.

The coordinates location does not point to the Stone of Jas or the ritual site, but it points to a location close to both. The ritual of the Mahjarrat takes place to the east of Zemouregal's fort, and the Stone of Jas is hidden within a cave accessed from an area south of the ritual site.

Trivia

• Kethsi was discovered exactly 3 months before the release date (14 September) of the quest Ritual of the Mahjarrat.
• With the release of Fate of the Gods, the destruction of Kethsi becomes ironic: The Elder Gods need as many prosperous worlds as possible, yet their own tools are destroying these worlds.
