Entreating Ingress

Entreating Ingress is a forerunner shield world that functioned as a portal nexus for nearby forerunner installations. Upon the firing of the array, however, the shield world's connection to the domain and the portal network to the other installations was permemnantly severed.
==History==
===Creation and Forerunner-Flood War===
Entreating Ingress was managed by the forerunner builder Hoarder-of-Wisdom during the Forerunner-Flood War until the Flood discovered the planet. Hoarder-of-Wisdom was able to contain the parasite by using himself as bait, trapping them inside a massive abyss that was sealed by the sentinels nearby. The shield world did not have a monitor active to maintain it, leading to ineffective sterilization methods and kept the flood in the inner-shield world alive. In the interior of the shield world lies a temple-like structure known as the “Gate”, where forerunners would ferry resources, supplies and equipment from the other installations to the shield world, to be transported off-world in massive cargo craft.
When the Halo Array fired, most of the Flood biomass trapped outside the shield world was destroyed. The little that survived were sealed inside the abyss, the flood could do little more than build up its strength and bide their time. The array also disrupted the portal network, rendering Ingress useless and the forerunner installations it connected to permenantly disconnected.
===During the millenia===
Due to a malfunction with the sentinal systems, Retriever sentinals began mining the nearby ice moon and transporting them onto the shield world. Due to the shield world's position, the ice melted and created a planet-wide ocean with former forerunner spires acting as supports for islands as the centuries flew by.
===Post-War===
Jegi Haram, a warlord from the Covenant Remnant, discovered the planet on November 2558 in his misunderstood plan to become immortal by entering the Domain. He was unaware that Ingress simply functioned as a portal nexus. 
He was deceived into releasing the Flood and subsequently killed by the Gravemind. After being killed, Jegi’s remaining forces descended into the lake and attempted to re-activate the local sentinal control hub. Although they were successful, the Flood swarms and the gravemind’s tentacles overwhelmed their forces. Lezo Gohom’, Jegi’s enemy, had followed him and assisted the sentinels in containing the flood contamination, and was forced to leave by the sentinal assaulting his carrier.
