May I present more fodder for the Mazzarin/Alric theory?
I don't know if anyone's pointed this out before, but look at the dialogue in "Out of the Barrier"
Alric: Ah, Sinis. I thought you died when Mazzarin collapsed the Shrine of Nyx upon you.
Sinis: Indeed Alric. Then I'll wager that you thought you'd seen the last of me.
Alric: I HAVE seen the last of you...
*boom* *bang* *pow* etc.
Look at what Sinis says. "YOU thought YOU'd seen the last of me." Mazzarin died in the Wind Age, so Sinis must have been buried under the Shrine sometime in that age or before it. Then why does Sinis say "you" to Alric, who was born over a thousand years later? Sinis says "seen the last of me," not "heard the last of me," implying that Alric was somehow there. Could it be that he knows they're the same spirit?
Of course, another explanation could just be that "you" just means 'the Light' in this case. This seems pretty flimsy though, especially since (unless I'm misremembering), he calls Alric by name.
Another possible way to explain all this is to argue that Sinis was a good guy when he was buried... by Mazzarin, who was at this point a Shade. Sinis is then resurrected by the Dark as a Shade. If Mazzarin was a shade when he buried Sinis, the time limit disappears and this could have been a recent occurence. On the other hand, though, Alric's speech "Ah, Sinis! I thought you died..." seems full of swagger, not sorrow. You'd think that if Sinis being undead were a new thing, Alric would be expressing shock or sadness, not boastful self-confidence.
