Okay. We have seen five thus far.
Okay, so through-out the story there seems to be little doubt who the Blue Soul Star AKA the Astral Influx belongs to.
Ciro. Ciro finds it first and some early hints by the GM implies something bad were to happen if we were stupid enough to break it.
But to cap it off the above picture says that the Astral Influx's Soul Gauge is Ciro's Soul Gauge. Also:
http://www.bay12forums.com/smf/index.php?topic=121809.msg3994004#msg3994004 There is a code here.
http://www.bay12forums.com/smf/index.php?topic=121809.msg3994103#msg3994103 The solved cypher mentions that Astral Influx is Ciro's (and both by name).
As a result of the event surrounding its appearances there appears to also be no doubt who the White Soul Star AKA the Reverant Savior belongs to.
Rilita. Rilita never comes into contact with her Soul Star, but her dramatic transformations (cuz she had two) make it pretty apparent.
This part of this conversation seems to imply that the Soul Stars must be found like Ciro's. Perhaps this is part of the cycle. Either way the appearance of the Reverant Savior during Ciro's Over Soul seems to cap off the owner as Rilita.
Also as a bonus:
The computer mentions when Rilita died here, her soul was prematurely destroyed. It seems that if someone dies without their Soul Star in their possession or near them... shit happens. Also we can glean from this and part of the mysterious conversation that Rilitia was always meant to do this sooner or later. (So what you get to take away... DO NOT LET A CHARACTER DIE WITHOUT THEIR SOUL STAR AND DO NOT BREAK THE SOUL STAR. Also DO NOT CROSS THE STREAMS. IT WOULD BE BAD.)
The Yellow Soul Star is in Proxxy's possession and her symbol in [sinful] matches it's symbol.
The Mechanic: not a bad person, just kind of impatient and greedy. Since he/she is the First, that technically makes him/her the lowest on the chain of command, so he/she just does what people tell him/her to. Smart enough, though, to not free you.
The description of the mechanic fits and mentions the Mechanic being the First.
The First sibling is called down to [sinful]'s prison and is mentioned to have electrical specialty. At this point, I would say it is safe to say that
Proxxy fits this bill five ways to Sunday.
Now here's where it gets hard. So far people seem to have similar theories as to who the remaining Stars (Red and Green) belong to. Now so far either no one has gotten it right or the proof is lacking. So I'm trying to find this missing proof or at least draw attention to what is missing.
Okay. Most obviously
while the T symbol is on Cain's board... the symbol for the Green Star AKA Illborn Exchange is missing. This seems to hint at the possibility that this is Cain's Star. Okay a possibility. We know it was stolen by the Thief (the person matching the T symbol of the Red Star). Problem is we know that the Soul Star was given to Al by the Chief, but there is no way to prove the Chief is the Thief. But we can guess that an owner of a Soul Star would willingly give it up. As I mentioned above a Soul Star is connected to the person and if harm comes to either while separated... shit happens.
Now so is there anyway to prove that Cain and Illborn Exchange are connected. Well...
The screen seems to imply that something may have happened to [sinful], but that he was safe. Now [sinful] is on DL3 and the breach was on DL2. The breach (if you read the monitors) refers to a breach of the cycle... not a breach between dungeon levels. So what could have put [sinful] in danger. Illborn Exchange was in DL2 and within the range of the breach (Rilita's soul being destroyed).
The fact that Proxxy left behind Cherish might be because she didn't want to bring Cherish and therefor Illborn Exchange to close to Cain... because chances are he could have used it to escape. At the same time though, she doesn't want to simply leave Cherish with two Soul Star completely unchecked (I imagine).
As for the Red Star other than the connection to the Thief... I got nothing. Its weird that it even shows up in the set during Ciro's Over Soul. I assume it has something to do with the Ciro's Astra Influx coming into close proximity to the other Soul Stars or their owners... but at what point did that happen with the Red Star. I think I've conclusively got all the evidence for Blue, White, and Yellow. There's a lot of circumstantial evidence for the Green Star, but nothing I feel makes it 100% tight... though I'm pretty sure from what I got that Illborn Exchange is Cain's Star. The Red Star is the anomaly... unless Ciro's contact with the Blue Chick (Floe?) has something to do with it...
Does anybody have any hints I might have missed...
