I've just finished reading The Outcast Dead (I'm a little behind everyone else) and while I thoroughly enjoyed most of it, the ending left me pretty dissatisfied. My main point of contention: what was the point of having the Thunder Warriors in it at all? All we are left with is the knowledge that some survived and have possibly managed to sort out their organ issues. So what was the point? As far as I know they don't play any role in the Heresy later on. Anyone shed some light on this? Spoilers in the later books kept to a minimum pls.
PS I assume Severian will turn up later on in the series, so I'm not too bothered that he was just forgotten about.
