I tried to summarize what we know about the problem. Unfortunatly, I did not manage to get any insights, only some speculations which are probably wrong.
About first daemonic incursion and first Fateless
1) Accorfing to
Inge, long time ago Sea Giants learned how to pass "on the memories of the life they lived one on to the other."
2) Wild speculation: could it be that Inge knows this from the book she
translated for the Eriran the Seer? "I do not think the Lady would mind it I translated this. The Keepers of the Deep might." Who are these keepers: Giants, Oceanids, Formless?
3) For those, according to
Giants, approximately twelve centuries ago Ikomi unleashed Neverborn (anjo-oru) on them. They survived only because of first group of Fateless, a Roman legion. They died in a war, "breaking the wheel of fate".
4) Roman legion was involved in some kind of "Mariner's wars". It was
Mariner who led humans on Sunset Islands, and it was
those Landfall which happened 1349 years ago (so it probably should be not twelve but thirteen centuries, or maybe archives are incomplete). Unfortunatly, Zaia did not wrote any legends about Mariner so far.
5) Also, these Giants cherished sea cats. Also Roland thinks that Ripper found something odd in Marcella, "before the rat, before even the first time we want through the straights". At the same time Ripper's
interlude does not show that he is some kind of secret agent.
About Formless
6) According to
Ohun, Formless are spirits from the times when the world was young. They rejected Elnu's order "those of the sea must swim in the sea and not walk on land or fly in the air" and run into deep. There they cherished a lot of lesser Formless which are "shapers of flesh".
7) Formless took the form of the bodies of Alum and Onogu Iranea. According to Ohun, it was "test of manhood and the proof of its mastery". It's
possible that Formless did the same with shaman of Knikut near the Mouth of the World.
8) According to
Ohun, (although I can be mistaken because the wording is unclear), Formless also fight with daemons: "We are not the only ones who can see what is coming, the seas froth red deeper that the eye of man can pierce, this was a test yes, but also a plan with a purpose")
9) Wild speculation: may be daemons a result of Elnu's wrath against Formless? This does not seems very likely, because why now?
10) Lina Osane
had some kind of connection with "Onogu Iranea" and disappeared soon after his death, probably went to the Formless.
About Unke the Red, a.k.a. Readman
11) It
happened "more than six hundred years ago", and it was the latest war in Anwa history. Untill now.
12) According the
legend, Unke made some kind of gantlet from the star metal. It could be those gauntlet with which Unke broke Marcella's desk to get rid from Zentragt. It also could be an artifact made by daemons to sell this story better.
13) Unke
killed some weird south beast for ivory, and this beast before the death cursed Unke with infertility. Holy man of Ashinu telled Unke that to lift the curse he must conqure all Anwa islands.
14) According the legend, Unke "bedded a mermaid from the deeps and sired upon her twenty sons". It could be only a legend. Or a hint to the connection with Formless (or other sea fraction).
15) Unke had some strange ally named
Shadow, capable to many strange diversions. It may or may not be those shapeshifting assasin who
killed Negu.
16) About strange assasins: there was a spy on Marcella when she first left Orinilu.
According to the divination of lightning spirit, "It was an a man in black guise and black of heart, a killer though he did not come to kill. He was here at the behest of another, one who means ill not just to this ship and all upon it but to the world entire". Although it is probably another assasin connected with some Orinilu shenanigans.
17) According to Unke, "They ("Hollow" – Obari and some type of "Maggot") are but the smoke that comes before the fire and so they come now to me for I am of the Land and I alone can keep them here and away from the hand of their masters in the south". We
know that in the south some kind of "shadow man" (former Anwari) has taken the mind of Balwa Feku even before the arrival of Marcella. Aphiwe
tried to counter this shadow man, but it was year ago. So at least something in the south is wrong indeed.
18) It's unclear if Unke lies or not. During the
battle with Undead Giant and Dahzagan warrioirs cried "For Obari", and during the battle with Urdefhan they cried "He is come!", "Breaker of Kings and Lord of the Land!", "All is for Him, all the islands! All the World!". Although, anjo-oru are famous for lie.
19) Unfortunatly, Zaia wrote nothing about how Unke died.
Miscellanea
20) According to hedon's
skull, "It was more than one, those who made the promise to you and your kind in exchange for meddling with us".
21) Somebody
moved Red Lion's tribe against Roland and co after the victory against dragon. Skull is not questioned yet.
22) Ohun's
impression about dragon's egg was "The eldest seed made onto stone; In shroud of gold, in troth of bone; The dance of ages grows too swift; Beware thou mortals the parting gift". Zaia wanted to seach the answer in Orinilu, but was too busy. Also, we lost the egg.
23) Also, we broke anjo-oru conspiracy in the north, but their tactics is well reveiled. As for some deeper meaning, Ulk's head is not questioned yet.
