what is formless oedon's role in the war of the great ones
I might be barking up the wrong tree here given I don't play the Souls games, but as far as I understood the Formless Oedon is just a standard rune that gives you effects, aye? Or are you talking about the bloke it came from?
what can you tell me about the reapers?
Ah yes, 'Reapers'. The immortal race of sentient starships allegedly waiting in dark space. We have dismissed that claim.In BioWare's handicapped conclusion of the Mass Effect trilogy, the AI are a combination of organic and synthetic material to produce mega AI with the purpose of solving the problem of AIs wiping out galactic civilisations through wiping out galactic civilisations before the AIs they can develop do it.
The Leviathans were a race of space cuttle-fish that had the power to control other species, which they referred to as "Thrall Races". They used the Thrall Races as slaves, allowing them to lead an oppulant, work-free lifestyle. The Thrall Races were displeased at this, and began creating AIs to do the work for them, so the Thralls could also live oppulantly. Unfortunately, the AIs would eventually rise up and attack the masters, wiping them out. This happened with every Thrall Race, and so the Leviathans developed an AI called The Intelligence to resolve the problem.
The Intelligence bugged out based on the data it studied and decided that the problem was that every 50,000 years, there would always be an AI civil war that lead to destruction of a civilisation. It's solution was to simply wipe slate every 50,000 years or so. It created Harbinger, the first Reaper, in the image of the Leviathans as its tool to enact this new policy change. The first harvest was quick as none of the involved races were prepared, and only a few hundred Leviathans survived by hiding.
A Reaper is born out of every harvest, with its internal biomechanics developed from the organic material of, and the core shaped in the likeness of, the most "prime" race that exists in a set cycle (as an example, Humans were elected the Prime race when we destroyed Sovereign). Reapers house many AI programs ("We are each a nation"), and their core directives are to wait in Dark Space (the space existing outside the Milky Way galaxy) until one of the Vangard Reapers initiates a harvest, at which point they spread across the various systems to begin their assault.
The Reapers created the Citadel and the Mass Relay technologies as a means to control the development of organic species and to develop back-doors they can use to conquer the galaxy quickly (if something is done for the races, they won't bother making or investigating it themselves). It is assumed the Reapers created the Keepers from a previous civilisation to be the maintainers of the Citadel, and that Reapers may collect members of a prime race and convert them with augmentations into subservient operatives to enable their will in-between cycles.
There are multiple classes of Reaper, but all are space-flight capable, and all unconsciously generate an "indoctrination effect" (even when not powered/active), similar to the Leviathans, which can have devastating effect on a target's mental functioning.
