Arcadia Forerunner ruins

The Arcadia Forerunner Ruins are a series of Forerunner ruins in the jungles of planet Arcadia. They were a site of a conflict between UNSC and Covenant forces in 2531.

Summary
The ruins consist of numerous temple-like structures, and a main structure, which is likely an entrance to a some sort of underground complex. Not much is known about the functions or purpose of the structures.

History


In 2531, during their search for a key to activate The Apex, the Covenant showed interest towards Arcadia, as a structure on Harvest pointed them towards the planet. The Covenant forces traveled to Arcadia with two CCS-class Battlecruisers. One was destroyed, but the other one engaged in surface activity, attacking Pirth City and searching for Forerunner artifacts on the planet. After they found the ruins, the Covenant deployed a massive dome-shaped energy shield on the planet surface to prevent the UNSC forces from reaching the structures.

The UNSC forces managed to breach the energy barrier with a few Rhinoes, and after securing the area they established a base and proceeded to investigate the area. However, the Covenant had started to build a Super Scarab in front of the main structure, to keep the UNSC forces away from it. The Covenant tried to destroy the UNSC base, by using the Scarab's main cannon to destroy the temple structures protecting it. However, the UNSC forces managed to weaken the Scarab by destroying its power nodes, and eventually the Scarab itself. When the Scarab had been destroyed, Ellen Anders proceeded to investigate the area, guarded by Sergeant Forge.

As the Covenant didn't seemingly find anything of use from the ruins, the Arbiter travelled to the Shield World to consult the Prophet of Regret for advice. The Hierarch ordered the Arbiter to capture professor Anders, as she could possibly be used to activate the installation.

While Forge and Anders were investigating the ruins, the Arbiter appeared, and captured Anders. Shortly thereafter, the Covenant ship jumped out of the system, and the followed.
