In Chapter 9, it's Cû-jara Cinmoi, rather than the usual Cû'jara Cinmoi.

In Chap. 18: The Golden Room:

“They began moulding themselves the way potter’s mould clay,” the unscathed one said.

potter's -> potters

Maybe it was Harry?

Kiünnat is spelled Kunniat in the glossary.

Wait, does Bakker usually use British English? Mould or mold?

I assume the editor-interns decided that 'Canadian' has some peculiarities and just left it in because otherwise they'd have to read it all much more closely. 
(Because I assume a reasonable publisher in the US uses US standard english when publishing/editing)

If I remember correctly, Bakker uses several Britishisms throughout the series, but I can't recall them at the moment...

Spotted emend somewhere in the glossary for what I assume should stand for amend.

In the glossary entry for Nil'giccas (page 545 on the paperback copy):

eldest son of Sin'niroiha and Tsinirû

And in the glossary entry for Sin'niroiha (page 567):

his marriage to the sorceress Tsinirû, who would bear him Nil'giccas, his only son

One of these isn't right...

[Walter]

eldest...and only!

[ThoughtsOfThelli]

eldest...and only!

"Eldest" shouldn't really be used if there's only the one son, it's misleading.

Unless there were younger sons who died in infancy/childhood or something like that. There's no evidence to assume this was the case, though.

[Wilshire]

eldest child, probably.

[ThoughtsOfThelli]

eldest child, probably.

With others being daughters? It's possible, I guess.

[Wilshire]

That's my best guess, its slightly excuses the mistake. Still wrong, still irritating.

Looking through the glossary again - on page 457 (paperback), on the entry for the Amiolas, Nau-Cayûti is spelled "Nau-Kayûti" (similarly to the "Kû'jara Kinmoi" mentioned earlier on this thread...).
Might be a variant spelling, of course (Nau-Cayûti -> Kayûtas, Celmomas -> Kelmomas?), but it has been consistently spelled with a C before.

And there's an age that doesn't seem to make sense - on page 453, on the entry for Agabon, Coithus, his dates of birth and death are given as 4124 and 4132. Admittedly, I don't remember this character (a reread is needed...) but it seems very unlikely that an 8-year-old would be marching with the Ordeal...
