(Non-spoiler) quotes from the recent QA about the series on Tor. Erikson’s own words:
Writing it felt like more than one lifetime: it felt like hundreds of lifetimes, all crowded into a single place and a single time.
I died and was reborn a thousand times in these ten novels, and I wonder now how many times a single soul can go through that.
I laid traps for you time and time again, pits for your unwary headlong rush – the plunge intended to make you feel whether you wanted to or not. With luck, you stepped into a few of those. If I was a god, I’d throw you into every one of them.
That last one is almost chilling (see in the context of the “Magus” recent quotes here on the blog). I have this idea that Erikson isn’t completely conscious of the implications of what he writes, yet he shows being so lucid.
