I don't believe there is any mention at all of Typhon's children in the Urth
Cycle, and the only black bean story I recall is the one told by Jonas at
the very end of SHADOW, which makes no mention of the sun. Anyway,
"grave of the sun" sounds like that sun is already dead. Where is the quote
found?
