In 'Dreamfall: Chapters' we're introduced to Etta and Saga. These are references to Norse Pagan Mythology; Etta refers to Edda, the Norse Pagan myths that were passed on through generations until they were written down. There are two types of Eddas; The older and the younger.
When it comes to the older Edda we don't know who wrote them down, but we know who wrote the the younger Edda;; Snorre Sturlason. The stories are considerably different when you compare the younger to the older Edda, and we know that Snorre based the younger Edda on the older.
Snorre changed these stories, but why? Well, he was an opporunistic self-centered asshole who would do pretty much anything to advance his agenda. He was also a huge proponent of the Christianization of Scandinavia. So what happens when a person, who is biased towards the concept of monotheism, rewrites and changes what has already been written down?
The Azadi shows up with their concept of one true deity proclaiming that all other deities are false idols, that the concept of magic and science separated and kept balanced is opposed in favor of their judgment and afterlife concepts. And April, the chosen one who would forever serve as the savior and protector of the two worlds, has changed into a brutal and deadly enemy; a liar and a false prophet.
Then there's Saga...
Saga incorporates details and stories from both the older and the younger Eddas creating a new story where the two Eddas overlap; Frøya and Frigg are two different deities, then all of a sudden they're not, they're one and the same. One deity becoming her own mother, sister, daughter...etc..
This is why Lady Alvane, Magnus, Edda and Saga lives in the exact same house not governed by time, yet they're not there at the same time; they exist in the same place but in different realities within the Storytime;
Lady Alvane is the older Edda; she delivers her stories orally and in that cyclical fashion mentioned earlier.
Edda is the younger Edda; Remember her typewriter? She doesn't need to apply the cyclical method because she doesn't need to remember the stories, she writes them down and there they are.
Saga is Saga; She has access to both the older and the younger Eddas so the stories she tells contain elements from both. This is why she is referred to as 'The girl who walks betwen worlds'. Since she has that ability, she can also change the past. She can override Lady Alvane's story and ship her off to oblivion, effectively killing her off;
Lady Alvane: "And so the story goes... How strange it was to tell it again, to remember...April Ryan. That was such a long, long time ago. And now...now my story is almost over as well."
Crow: "Ah, you're as healthy as ever. You still got a lot of life in you... Wish I was half as lucky."
The reason why Crow is so very important to this story is because of his true identity; He is Odin, the All-father. Without him there would be no Lady Alvane, no Etta and no Saga. He must remain as a constant in all of the stories, because if you remove him the story never existed to begin with; They're all connected through him because the entire story's backbone is Norse Pagan Mythology.
Now that you know who he is, you can start identifying who the different characters in the story represent in the Norse Pagan myths. Not only will things start to make more sense, you'll also know certain details that are yet to be revealed, and may never be revealed.
From April Ryan's diary: 'I'm going to the pond tonight, to say goodbye. I haven't been there in a long while, not since that CRAZY day. Well, I have to see it one last time, or I'll never get it out of my head.'
