During the [[Forerunner]]'s [[Forerunner-Flood war|war]] with the [[Flood]], Flood forces '''attacked''' [[Zeta Hydronis Secundus system|a Forerunner star system]] inhabited by [[Miner]]s. The Flood was initially held back, but with the assistance of the [[Gravemind]], the parasite eventually prevailed.{{Ref/Reuse|CF}}

==The battle==
[[File:H5G-Shattered world.png|thumb|left|250px|One of the colony planetoids torn apart by the Gravemind.]] 
During the Flood's conquest of [[Milky Way|the galaxy]], the parasite arrived at what would be known by the [[UNSC]] as the Zeta Hydronis Secundus system. Protected by layers of [[hard light]] and exotic matter, and fitted with energy projectors, the system's planetoids were considered impregnable. Due to the advanced defenses, the Flood's initial attack failed, however, the Forerunners' victory was short-lived, when the Gravemind itself turned an infinitesimal portion of its immense intelligence to bear on the problem.{{Ref/Reuse|CF}}

Grasping impossible [[star road|filaments]] buried beneath reality by the long-vanished [[Precursors]], the Gravemind pulled at strands that twisted and warped real space. Walls made of collapsed starmatter cracked and shattered, entire [[Forerunner fleet|fleets]] of kilometer-long warships tasked with defending the system vanished in flares of light, and [[Ecumene#Former ecumene worlds|colony]] planetoids were ripped apart. With the Miners' defenses compromised, the Gravemind poured billions of [[combat form]]s onto the surfaces of the colony worlds and into the Miners' installations. Those that survived the initial onslaught could only activate failsafes and await their deaths at the hands of the parasite.{{Ref/Reuse|CF}}
