Elder Artefacts

The Elder Artefacts, also referred to as the Elder Twelve, are a dozen of immensely powerful, divine artefacts that grant their users powers beyond mortal capabilities. They are conduits of power created by the Elder Gods used to carefully craft perfect details in their creation and, there are twelve of them in the entire universe. Only six of them are known thus far.

Stone of Jas
The Stone of Jas is an elder god artefact of immense power that grants its users part of it. It is guarded by the Dragonkin, a race created, enslaved and cursed by Jas to feel agonising pain at every moment, mainly when the Stone is being misused. When the Stone is misused, the Dragonkin are given equal amount of power that was given to the user and are tasked to destroy them, making it one of the most risky artefacts to be used. It has a long history of use and relocation. Notable users of the stone include Guthix, the Kethsians, Zamorak, Saradomin and Lucien. The stone is also the cause of the existence of rune essence, Daeyalt ore and the Fist of Guthix. The Stone of Jas also played a role in the destruction of the Forinthry site. With his powers enhanced by it at the end of the God Wars, Zamorak seared away the entire continent.

Elder Staff
The Staff, most commonly known as the Staff of Armadyl is an artefact of incalculable power that was used and created by the Elder Gods. It was found by Guthix at Gielinor during the First Age when he was travelling between dimensions with his sword (see below). He wasn't interested in it and hid it before sleeping in the middle of the perfect world to let mortals enjoy it. After that, it was found and used by the god Armadyl during the Second Age and soon became linked to him, becoming known as "The Staff of Armadyl". His followers adopted the symbol from the staff and it became his symbol. Notable users of the staff include Zamorak, Lucien and Sliske. After Zamorak had used the staff, it was placed under protection of the Guardians of Armadyl, who were tasked to protect it. The staff was referred to as "a god slayer" by Guthix. It amplifies its user's power and magical capabilities and serves as a conduit for power as well. One of the most important events in which the staff was involved was the death of Guthix and the defeat of Zaros.

The TokHaar
The TokHaar are an immortal race created by the Elder Gods to build the mountains of Gielinor, made up purely of rock and lava. They forged the Xil to dig up the earth and rock, the Mej to blast it into size that the Ket could carry, and the Hur to craft the sediment into cliff-faces and slopes. The TokHaar were forged in the Elder Kiln, where they remain to this day, deep inside the Karamja Volcano. Some TokHaar decided to defect from their task and build cities; these were known as TzHaar. For being distant to the Elder Kiln, they are mortals, weakened and with many reproduction problems. Over the years, the TokHaar fell into oblivion but were rediscovered when the TzHaar conducted an expedition to the sacred Kiln in an attempt to find out why the volcano was cooling down (gradually causing their extinction), which turned out to be a TokHaar plot to attract the Tzhaar to the Elder Kiln. According to the Tokhaar, gods are beings that abused the artefacts of the Elder Gods in order to gain a massive amount of power.

Elder Sword
One of the most notable artefacts is Guthix's sword. It was with this weapon that Guthix, after finding it on his plane during the Naragi God Wars, slew Skargaroth and ascended to godhood. After this he used the sword to cut open portals, which allowed him to travel across worlds. The sword currently lies shattered in Guthix's Cave, too dangerous to be used. This sword is not to be confused with the sword found in the Wilderness associated with the Edicts of Guthix.

The Elder Crown
The elder crown is an artefact used to locate all the other artefacts, being quite useful for someone wishing to track down all artefacts. However, possessing any of the other artefacts will likewise reveal the crown's location. The crown is in possession of Saradomin, and has been for much over 10,000 years, for he wishes to claim the other artefacts for himself. He eventually found the Stone of Jas during the Gielinorian God Wars, but it soon fell into Zamorak's hands.

Horn
Upon arrival on Gielinor, Guthix started to explore the world. One of his discoveries was the Elder Horn, which he kept hidden. This artefact and its effects remain unknown.

Existence of others
It was long thought that the Stone of Jas was the only item that belonged to the Elder Gods (or only Jas, since there was no confirmation at the time as to whether more existed or not). This has recently changed. In a lore livestream, confirmed by Mod Osborne.. The other six artefacts are to be revealed soon.

Trivia

 * The elder sword, which can open portals between worlds, could be a reference to the titular Subtle Knife, which has a similar ability to open inter-dimensional portals.
