Retriever Sentinel: Difference between revisions

Dark gray in color, Retrievers are massive and powerful [[Sentinel]]s that are slightly smaller than the average [[human]] [[UNSC frigate|frigate]],<ref name="hitd103"/> which are about 478 meters in length.<ref>'''[[Halo Encyclopedia]]''', ''page 259'' (2011)</ref> The upper section of a Retriever is vast and wide, while the lower section is lined with numerous mechanical, tentacle-like "legs" that move in pursuit of objects. Glowing eye-like lights are installed on the front of each Sentinel.<ref name="hitd103"/> When not in use, the legs remain in a closed resting position on the underside of the Retriever's hull.<ref name="hw2">''[[Halo Wars 2]]''</ref>

A Retriever is capable of producing an [[Artificial gravity|artificial gravitic force]] that allows it to remove materials from a world's surface. Once in position above an acceptable place to harvest, the Retriever deploys its blue, gravitic beam towards the world's surface and begins hauling chunks of land caught in the beam into its underbelly.<ref name="hitd103"/> The mining process utilized by a Retriever is noted to create a tornado-like effect as the ground is pulled into the Sentinel's hold.<ref name="hitd272"/> If deemed necessary, a Retriever is capable of connecting and merging with another Retriever and forming a single unit. Combined Retrievers somewhat resemble an average Retriever, though they seem to be more effective in combat and are significantly more maneuverable. With no apparent drawbacks, a combined Retriever seems to take on the benefits of both Retrievers' speed and weaponry.<ref name="hitd122">'''Halo: Hunters in the Dark''', ''pages 122-126'' (Google Play edition)</ref>

{{Quote|When we first arrived here, the Ark had suffered great wounds from our war against the Covenant, and so we activated dormant Retriever Sentinels and deployed them to strip-mine lifeless planets for the materials needed to repair the installation. Like watching a sleeping giant nudged into wakefulness, the reconstruction slowly reached full automation until we were no longer needed to guide the Sentinels and could simply sit back and record the wonder of a world being reborn|[[Nathaniel Palmer|Nathaniel J. Palmer]], an archaeologist of Henry Lamb Research Outpost<ref name="old wounds">'''Halo Wars 2''', ''Phoenix Log: The Healing of Old Wounds I''</ref>}}

Doctor [[Luther Mann]] theorized that the dormant Retrievers could be reactivated and utilized to repair the Ark, opening slipspace portals to strip-mine uninhabited planets for the resources and minerals required to repair the Ark.<ref name="hitd361"/> In [[2557]], a human research team traveled to Installation 00 aboard ''[[Eden Rising]]'' to establish a permanent base on the Ark, [[Henry Lamb Research Outpost]]. Desiring to repair the installation, the researchers activated the dormant Retrievers,<ref name="pl henry lamb">'''Halo Wars 2''', ''Phoenix Log: Henry Lamb Research Post''</ref> under the guide and direction of the [[smart AI]] [[Isabel]]. To gain resources, the Retrievers were deployed to strip-mine lifeless planets. Before long, the Retrievers were able to enact repairs unsupervised,<ref name="old wounds"/> leading to Isabel and the researchers setting to the task of cataloging and analyzing the installation.<ref>'''Halo Wars 2''', ''Phoenix Log: Isabel''</ref> The Retrievers acted quickly and within months had largely restored the Ark to its former state,<ref name="pl retriever"/> as well as constructing another [[Installation 04C|replacement Halo installation]] at the Foundry.<ref>'''Halo Wars 2''', campaign level, ''[[From the Deep]]''</ref>
