Editing Upgrade seed

{{Quote|The [[Forerunner]]s were master shipbuilders, among other things. They were explorers as well, spreading across a galaxy of three million occupied worlds. It was not uncommon for them to find themselves in contact with other species and races with rudimentary ships such as yours. They utilized [[design seed]]s to build their own ships from local resources if necessary. But there were many occasions when resources could not support a design, so the Forerunners used whatever local vessels they could obtain and created an upgrade seed - hard light instructions, blueprints, if you will, which bonded to an existing structure, reinforcing the materials, molding them as needed, and upgrading components and systems.|[[343 Guilty Spark]] explains the upgrade seed to the crew of the ''[[Ace of Spades]]''.{{Ref/Novel|Ren|Page=177}}}}

An '''upgrade seed''' was a type of [[design seed]]{{Ref/Novel|Ren|Page=210}} utilized by the [[Forerunner]]s to upgrade vessels of other species to have Forerunner technology upgrades within the ship's original framework of operating functional capability.

Upgrade seeds were designed to be tailored to specific types of vessels from races other than the [[Forerunner]]s. The upgrade seed can be designed to not change the outer appearance of the vessel. Instead, the upgrade seeds would only strengthen its existing materials by [[hard light]] bonding. Inside, quantum and hard light filaments would intertwine with the ship's existing systems, directed by smart upgrade code, to create a custom integration between Forerunner technology and the ship's current specifications and technologies. As a result, the upgrades were limited by the limitations of the ship's original design. While the designs could be applied in orbit, it was better to ground the ship and run on auxiliary power as the upgrade seed did its work.{{Ref/Novel|Ren|Page=225-226}}

While the upgrade seed could create an upgrade to the vessel's slipspace drive, it required a Forerunner [[slipspace flake]], like any Forerunner vessel did.{{Ref/Novel|Ren|Page=178}} The upgrade seed would then create a seamless integration between the vessel's original FTL drive, Forerunner translight technology and the slipspace flake taking into account the materials available to work with and the size of the vessel. Other known upgrades that the seed was capable of granting included stealth technology, upgraded comms, weapons and navigation systems, all kept with the framework of its original operating functionality.{{Ref/Novel|Ren|Page=226}} However, even with the upgrade to its drive, the ''[[Ace of Spades]]'' had limits to how far it could travel that Forerunner vessels lacked. For example, travel from the [[Orion complex]] to [[Earth]] - a journey of over a thousand light years - would take so long even with the upgraded slipspace drive that [[Rion Forge]] would be dead many times over before it was completed and the ship was only capable of traveling such a distance using a static [[slipspace portal]].{{Ref/Novel|PoL|38}}

After hijacking the {{UNSCShip|Rubicon}} in [[2554]],{{Ref/Novel|Pri}} [[343 Guilty Spark]] intended to take the ship to [[Trove]] to get an upgrade seed for the vessel, unaware that it had been destroyed in [[2531]] by the {{UNSCShip|Spirit of Fire}}. However, the ''Rubicon'' instead crashed upon [[Geranos-a]] and was destroyed.{{Ref/Novel|Ren|Page=143}} After being rescued by the crew of the ''[[Ace of Spades]]'', Spark decided to take the ship to the [[shield world]] and get an upgrade seed for it instead in order to continue his mission to find the [[Librarian]]. To help entice the crew's compliance, Spark offered them the opportunity to salvage from the planet.{{Ref/Novel|Ren|Page=143-146}} Following the destruction of the Etran Harborage debris field by a massive UNSC fleet, Spark explained his intentions to the crew and suggested that using an upgrade seed on the ''Ace of Spades'' would allow the crew to match the vessels of [[ONI]] and regain their personal property and the projections made by [[Little Bit]] of where the ''Spirit of Fire'' could've gone. After Spark revealed his history to them, the crew agreed to help him.{{Ref/Novel|Ren|24}}{{Ref/Novel|Ren|25}}{{Ref/Novel|Ren|Page=197}}

In order to get the upgrade seed, Spark took the ''Ace of Spades'' to the lost Forerunner world of [[Triniel]] which contained a [[Builder]] facility that had everything Spark needed to create an upgrade seed. After [[Rion Forge]]'s touch as a [[Reclaimer]] activated the facility, Spark retrieved a slipspace flake from the laboratory where the crystal was cut. Spark led the crew to the lab where the design seeds were created where he input the design specifications for a {{Class|Mariner|transport ship}} and designed an upgrade seed for the human vessel while the ''Ace of Spades'' crew salavaged from the facility.{{Ref/Novel|Ren|28}} Though originally hesitant to apply the seed, Rion agreed after being offered a deal by Agent [[Walter Hahn]] of [[ONI]] in order to give the ''Ace of Spades'' the advantage it needed with the upgrade process taking approximately eighteen hours, fifty-three minutes and eleven seconds.{{Ref/Novel|Ren|Page=223-227}} The cloaking technology the ship gained made it invisible to two searching ONI [[Prowler]]s{{Ref/Novel|Ren|Page=250}} which were also completely unable to catch up to or track the ''Ace of Spades'' when it jumped to slipspace.{{Ref/Novel|Ren|Page=254}} However, its cloaking was briefly penetrated by the AI [[Thea]] who detected a strange ship's signature on Earth that was registering as both human and Forerunner.{{Ref/Novel|Ren|Page=307}} Despite this brief penetration of its defenses, the ''Ace of Spades'' was never actually found by ONI and was able to spend a week on Earth undetected before departing right under the noses of Earth's [[Home Fleet]].{{Ref/Novel|Ren|Page=323}} The ''Ace of Spades'' became a one-of-a-kind fusion of human and Forerunner technologies. Unlike other human ships with Forerunner technology, it was not a human retrofit but a seamless, unifying integration led by Forerunner-driven technology.{{Ref/Novel|Ren|Page=265}}
