Benefactor is talking to the Kett?

There's plenty of backstory that's still a mystery, so it could be meaningful - on the other hand it could just as easily be a benefactor rather than the benefactor.

I was wondering if someone mentioned it on the forum already, I'm replaying the game now and last night I rescued Moshae Sjefa from the Kett facility. This is where I read this message and now I'm wondering if this is just some benefactor or THIS Benefactor?
I'm also intrigued by the fragment about showing the mail writer's world to the Benefactor and vice versa. If it's the Benefactor, when did they see the mentioned world, 600 years earlier? Are they still alive? So many questions!

And I really hope it's not the Illusive Man...

I kept wondering if the Kett are really Protheans that fled the Milky Way. I mean, Javik does mention how everyone they conquered became "Prothean", although I had assumed it to be a cultural change not a biological one.

In Javik's words: All those in the Empire eventually come to call themselves Protheans.

It is not biological and it is Bioware's way of explaining why the Protheans in ME2/3 are so different from the visions Shepard saw in ME1 - because Prothean is not a single species 

 It make no sense for the Katt to be linked to the Protheans. Milky Way technology is largely shaped by what the Reapers left. Protheans who fled 50000 years ago will be much more advanced than the Pathfinder team. Katt tech is not advance except in biology. Protheans have biotics and from one of the datapad, Katt clearly don't know what biotics are. Biologically, Protheans can communicate via touch, Katt cannot. It would be silly that u become more primitive after.absorbing the genetic code of a thousand species.

Simply put, Katt are too primitive to be Protheans.

I'm inclined to believe that this is either coincidence or a deliberate red herring. Given that this game also has Cora Harper, who's last name is shared with Jack Harper AKA The Illusive Man and who's first name evokes Eva Core, his lost lenore, and yet aside from the name there is no hint at a connection whatsoever between them, I wouldn't put it past the writers to have either used the term without considering the implicit connection, or otherwise put it there just for people to latch onto it to be deliberately misleading.

I'm more inclined to believe that there's someone on Bioware's writing team who has made it their mission in life to make a point that even in fictional worlds, not everyone with the same last name is related to each other. Given that in ME3 James Vega was originally James Sanders without any intentional relation to Kahlee Sanders and the name was only changed due to the fans not shutting up about speculation, and this time they just decided not to blink.

Anyway, on topic. The message in question is a kett talking to another kett from all appearances. If this is meant to be the Benefactor, this would imply one of two things; that they are the one who killed Garson rather than just having a sleeper agent do it, and in that case that they immediately jumped ship, submitted to exaltation by the kett, and rose to a position of some authority within the span of a year, or b; that they were a kett or were in league with the kett all along, even before the Initiative departed the Milky Way.

One of those is implausible and the other is borderline impossible and contradicted by everything we know.

The idea that the two galaxies are communicating is massively unlikely given sheer distance. The Initiative took 600 years to cross darkspace one way and the ships they used are beyond what either the kett or the angara have at their disposal. The Jaardan might be capable of it but we don't have any evidence there.

Also the Yahg being involved - unless we're talking about the specific Yahg that was the Shadowbroker - is impossible. They're an isolated, pre-spaceflight species. Their tech level is on par 20th century earth. They aren't communicating with Andromeda.

I see more parallels between the kett and the protheans - kett forcibly, genetically assimilate other races where as protheans did it culturally.

And the Shadowbroker did have some vague involvement - specifically he provided Alec resources in developing SAM. Outside of that I don't see him as a likely candidate for being the Benefactor, especially given that we know what happened to him, and given that this is obviously meant as an ongoing plot thread, I don't imagine that the benefactor will turn out to be an existing character from the original trilogy as that would mean there won't be any dramatic closure with them.

After reading the original ME:A synopsis, I'm inclined to think it's the same Benefactor IF they kept most of the back story in tact. Depending on how much they veered away from it, they may have changed it to be another benefactor with new reasons. But if it's the same, it would make a whole lot of sense in tying the mission together with IM & Cereberus's intentions for Andromeda. I guess we'll see though.

I have a feeling she was murdered because she was too powerful a figurehead to have poking her nose into who the Benefactor is. She was the perfect kind of charismatic individual to get people to join the Initiative, but once in Andromeda, too dangerous for the Benefactor to allow to be in control.

I am not sure, but I guess a part of the answer lies in the adapted story elements. Bioware used for MET HP Lovecraft novels, not at all but enough to see it to the end. I am speculating in MEA it is the same case. In this game they adapted sth from greek mythologie. (Hyperion (Titan of Light [brings the Nexus the light], Helius, Eos, ScottSaraSAM (three S, three children like Helius, Eos and Selene))

I would say in this case the answer who is the benefactor has something to do with the mythologie. (the evil uncle? the uncle from Eos, Helius and Selene)
