So have we fully deciphered this dude, yet? Here's what I have so far.
>One was a wayfaring knight, on an endless, forbidden search. Only the Abyss granted closure, if not reunion with his beloved.
Clearly talking about Alva here, whom we encounter further down in the RC.
>One met the dark with learning. But in the end, learned his knowledge was wanting. The world began without knowledge, and without knowledge will it end. Dost not this ring clear and true?
I want to say Vendrick and/or Aldia for this one, since he mentions wanting.
>One poor girl slew her own kin, but even so, was embraced, enveloped by the Abyss. Twas a comfort that neither moon nor sunless sky afforded her before.
Sirris, no question.
>And so, she lived in fear. Of the dark, of the things that gnawed at her flesh. And yet! The Abyss hath yet to produce any such creature!
Irina, with mention of gnawing.
>And so, despite his weighty armour, he lived in fear. Of a delicate thing, little more than a girl. Where fire resideth, shadows twist and shrivel. But in the Abyss, there are shadows none.
No idea. I've heard people suggest Eygon, but I'm not seeing it.
>Of all the Fingers, he alone was embraced by the Abyss. For he was human, and ne'er a grub.
Leonhard? Could be another finger.
