I talked with Tommy Andreason on Twitter about Chima..(And got some.. disappointing answers about Razar... just pulling reasons to ignore him that make no sense.. )
And he said this when I asked about Eris's phoenix soul
"She might be a reincarnation of Florax (Flinx's mother)."
This implies Eris has a phoenix soul because she is the reincarnation of Fluminox's wife and Flinx's mother, Florax
So this might mean Florax DIDN'T go to the sun(this makes more sense than just going to the sun after the failed illumintion...)
Meaning that John Derevlany either lied in that polish interniew about them going to the sun after the failed illumination or there was a big mistranslation...
