Regarding the comparison of Baldanders and Typhon: Baldanders strikes me very much as someone who is trying, by science, to transcend the human, and so someone who has made himself a monster; it would blunt the point of this if he were of monstrous origin. I take it, therefore, that 'Baldanders' is an assumed name, and that if he was born in the Commonwealth, he originally had a saint's name. (Or perhaps he was born in Ascia, and his real name is something like Devoted to the Interests of the Populace.)
We don't know enough about Typhon, I think, to say if his case is similar, but I don't think we can rule it out. Might there be a parallel between his adopting a monstrous name, and his wife and children's adopting monstrous names when they became the gods of the Whorl? (In which connection, it's worth noticing that 'Cilinia' is a saint's name, and its bearer should therefore, by the normal rules, be human.)
