Note: Everything in "Me:" quotes is based on my interpretation of what the supporters sent me, and may be wrong. But I believe the overall summary is pretty much the same. Regardless, if something was missed, reply to my post and I'll add that to my questions to both staff.
I'll be real with you, not blaming you or anything nor am I saying your instigating a specific response but the way you phrased those questions make the overall summary not the same especially in finepoint's case where he views it as SR.
You started off saying they're formed from legends, lore and beliefs but your every subsequent reply phrased it as "Because people believe this, spirits come into existence", "Because of people's beliefs, certain phenomena exists". This phrasing will always make a person's answer point towards subjective reality.
Beliefs, emotions, legends, rumors, lore etc is the number of factors that lead to the existence of a spirit sprouting but beliefs and emotions are basically not involved whatsoever. What leads to the birth of a spirit is rumors, lore/legends, the encompassing word for this is basically "stories". Widespread knowledge of these stories is what births a spirit and even then, just because a story exists doesn't mean a spirit will be born from it no matter how widespread it maybe.
Beliefs play no role whatsoever in the equation as Anos who spread the lore of Lay's mother, Kanon and other demons of the mythical era who spread the lore of Avos Dilhevia knew and
believed that they were spewing complete BS. Looking from the perspective of an actual spirit, Reno the mother of all spirits active goes out of her way to let people know that she isn't actually the mother of all spirits neither did she give birth to them heck she isn't the first spirit as some predate her. Her lore simply describes her as such which makes her their mother. Being the mother of all spirits enables her to summon, dominate and use their abilities. Her actual daughter (Misa) because of this can actually use the abilities of spirits as magic.
Looking at another spirit (Avos Dilhevia) the demons who actually spread the story of Avos Dilhevia of course didn't believe this existence was the demon king, they also knew who the true demon king was yet this didn't stop Avos Dilhevia from being born, neither did it stop her from inheriting almost every ability that Anos Voldigoad is capable of using.
Subjective reality can simply be described as the ability to turn fiction to reality and vice versa, warp/change reality according to one's beliefs regardless of common preconceived notions. In the same vein, type 2 information (regardless of what form it comes in be it knowledge or memories) is something fundamental that
describes something or the properties of what a thing is. In the case of spirits, their lore fits into the latter.
Type 1 information is simply knowledge, memories etc that has no bearing on reality regardless of its scope. Spirits aren't just abstract/incorporeal beings that come to exist just cause of the awareness of certain knowledge, we are told that this knowledge actively shapes/describes what and who they are
Your source is shaped by a rumor or legend. That means that rumor or legend has taken on a kind of power within you that gets converted into your source. If I link your source to Sheila’s, you may be able to send your power to her before it undergoes that conversion, helping her recover to some extent.
I've lost count of how many times I've stressed it, but they aren't simply abstract beings formed from type 1 information, it is instead converted into a fundamental form or nature that is then converted into their sources and bodies, shapes and describes their very being (the source makes a person who and what that person is and yes, this conversion and formation isn't limited to just their sources as their lore can be stolen from their body directly)
We made our way to the other side of the fog to see a completely transformed Aharthern. Every plant of the once lush forest had wilted, and the screams of fleeing spirits rang through the air. Huge beasts with silver fur and sharp fangs were dashing about the forest. And there were far more than just one or two— they were everywhere, gnawing away at the trees. The green rapidly wilted wherever they passed. They were devouring the spirit itself.
“Watch out!”
“Our lore will be eaten!”
“We’ll die!”
“Even spirits can die!”
In other words, the process is type 1 > type 2= a spirit. It is even skeptical of the first phase is even just type 1 cause the lore that forms a spirit on its own affects the things described in it such as every spirit being Reno child despite this not being true as well as demons being bound in service to Avos Dilhevia despite knowing who the true demon king is. Anos even tells his own subordinates to look into his abyss- which is a metaphor that means to analyze and gain information about something- to determine if he was the demon king or not.
Now SR would entail an entity warping reality based on their own perception so what entity exactly is making Avos Dilhevia the demon king or Reno the mother of all spirits? None, these things are simply so because the legends describe it as such.
I'll tackle the rest later
