For lack of any intelligent guess, I'll just analyze the riddle. Maybe something will come into my head while I'm writing.


To first of you, I'm just a tale, - the fact that it's "just" a tale brings me to the conclusion that they've never met, but the first of you has heard about the speaker
told by the skies, - Legate's comments make it sound like it is literally told by the skies, and the fact that it's specifically the sky is important
as they unveil - I was going for a canonical mention of unveiling, but I might have been overreaching here. It could just be a way of saying "revealing".
mysteries hidden long ago. - it's the mystery part that's troubling.

To second one, who's bigger still
than me, I'm first a fear until
I show him I can bring your friends;
his trust shall be of importance. - this verse sounds like the most straightforward thing in this riddle.

And to the third, whom you don't know,
I enlighten the terror's night, - the word enlighten is botherig me a bit - shed light or knowledge, or, in a wordplay, could be to make less heavy. Judging purely by the wording of the sentence, it sounds more like sheding light.
and in mine and the Other's - not one, not three, but two of them.
flight - to fly or to flee? I certainly hope it's not a flight of stairs, because that makes no sense.
I save more than the tale did show. - I'm wondering if this is a bit of poetic license or the "tale" really didn't appreciate the flight enough. Also, could it be the same tale as was referred to in the beginning? Hmm.



As a random guess, could it by the Sun or the Moon? No it couldn't. The first and third stanza could fit, the second fits with a stretch. And who exactly is bigger? Erm...never mind. (that's the general outline of my thought process for the past few days...)
