Precursor artifacts

Precursor artifacts are any objects of Precursor origin, particularly ones created and used by the Precursors themselves. This includes the various Precursor structures, devices, and other objects seen in the series. Some artifacts from during the time of Mar were also referred to as "Precursor artifacts" as he was associated with the Precursors. Precursor artifacts make up a large role in the series and are common in many locations.

Major artifacts[]

Name	Description
Armor of Mar	An ancient set of armor used by Mar in his ancient battles against the Metal Heads. Jak could collect the full set in Jak 3.
Astro-Viewer	An ancient piece of Precursor technology found in South Haven Forest during Jak 3. It is activated by five artifacts Jak collected during the game. It was used to hack into the Dark Maker ship.
Eco core	A major Precursor artifact situated near the Aeropan research rig used to stabilize and distribute the world's supply of eco.
Eco power sphere	In combination with dark and light eco crystals, this is one of the core power sources for the Planetary Defense System.
Heart of Mar	A large ruby gem, carved into the shape of a heart and set in Precursor metal. It is used to indicate location on the Rift Rider, while its counterpart, the Time Map is used to indicate time displacement.
Oracle	Large, Precursor metal devices planted in various locations around the world, allow Precursors to communicate to the people of the world. They often give side missions, award Jak with dark powers, and trade power cells for Precursor orbs.
Precursor staff	Notably carried by the Ottsel Leader and Veger, Precursor staffs are used to channel energy and command other technology. Veger used his to awake his Precursor robot, and the Ottsel Leader used his to transform humans to ottsels, give Daxter pants, and restrain threats.
Planetary Defense System	The core of the catacombs, the Planetary Defense System is a huge weapon that is activated by the eco power sphere and light and dark eco crystals. It was used in Jak 3 to destroy the Dark Maker ship.
Power cell	Described by Keira as "the most important Precursor artifact you can find",^{[note 1]} the power cell is used primarily as a power source but also as a bartering currency. About 90-120 Precursor orbs (which is the main currency) are worth one power cell.
Precursor orb	Used as the primary currency throughout the series. It is a floating, glowing, golden red, egg-shaped, Precursor artifact with Precursor writing inscribed on it. They can be collected and the value incredibly fluctuated throughout the series; hundreds of them found easily in The Precursor Legacy, while in the future (Jak II, Jak 3, The Lost Frontier) they were considered rare. In Jak X: Combat Racing, racers could collect them by the thousands.
Rift Gate	Used in conjunction with the Rift Rider to travel through time. It is activated by the Heart of Mar and Time Map.
Seal of Mar	The crest of the House of Mar and used to activate Precursor technology in Jak II and Jak 3. It apparently had ancient connections with other Precursor artifacts due to its importance, role, and abilities.
Precursor robot	Large, combatant oracles, used to obliterate any opponent of its controller. Both Veger and Gol and Maia used their own robots. See: Gol and Maia's Precursor robot
Precursor Stone	The last surviving Precursor "egg". It was used to power Mar's gun, and if cracked open would destroy the entire universe with its power.
Teleport gate	Also known as a warp gate, teleport gates could transfer its user to far away locations. It consisted of a round ring with a blue aura inside of it. When the user steps through the gate, he or she will travel to the designated location.
Time Map	Used in conjunction with the Heart of Mar, the Time Map indicates time displacement for the Rift Gate and allows its user to travel through time.

Minor artifacts[]

Name	Description
Beam Generator	An artifact required to activate the Astro-Viewer.
Catacombs rail rider	Used to traverse the catacombs.
Dark eco canister	An artifact found by Jak in Misty Island, he managed to activate it and used it to destroy a bone armor lurker.
Dark eco silo	Large silos filled with dark eco, most are underground except for the one that was nearly completely opened by Gol and Maia.

Precursor blocker	A strange device found at Snowy Mountain. It generates an energy field that pushes away anything that comes close.

Precursor metal[]

Precursor metal is a durable alloy used to make the majority of Precursor artifacts and devices, and can be gold or copper in color. Precursor metal is known to be considerably heat resistant (although not enough to withstand the heat of Fire Canyon), and was also useful for being impermeable to dark eco (e.g. dark eco silos, Precursor robots, and Maia's armor). Remaining intact for eons, it was used as the primary material for Precursor buildings, structures, and monoliths.

Precursor metal would sometimes be used in combination with stone or glass to form some artifacts and objects, such as floating platforms and oracles, respectively. Precursor metal was generated at least in part by Precursor robots, via a hydraulic chisel in the left arm shooting super-heating filaments, which they would use to carve fine detail.
