Gatherer Sentinel

Gatherer Sentinels are multipurpose Sentinels designed by the Forerunners with the functions of maintaining ecological stability in constructed biomes and the gathering of various living specimens for Lifeworker activities.

Design
Gatherer Sentinels consist of a fairly large main body with three red eyes and a holding tank for captured specimens on their backs, filled with a purple liquid. They have eight tentacle-like clawed arms, two much smaller arms, and four legs, although they are usually seen floating through the air. Gatherers are armed with an energy weapon similar to, though more powerful than, the Sentinel Beam, located below the tentacles. Much like the Sentinel Beam, the weapon can be detached and used as a hand-held weapon.

Operation
Gatherer Sentinels are typically networked in localized curation zones, with several operating under the guidance of a single monitor. When no such oversight is available, individual Gatherer Sentinels can function autonomously for long periods of time, falling back on underlying classification parameters and archival protocols.

History
Gatherer Sentinels have been observed operating from Line Installation 1-4 on an unidentified moon. During the Battle of Line Installation 1-4 in 2552, a group of Gatherers captured Margaret-053, Reff 'Talamee, Jubub and a Mgalekgolo who had all crash-landed on the moon and took them into the depths of the facility for experimentation.
