Well, all this debate about mechanical versus biological godlings leaves me to bring up an example of the human-looking ubermensch from Lake of the Long Sun:
councillor Lemur had his awesome mechanical (but very heavy) body that seemed totally human (except for that crazy tendency towards magnetism and self-illumination). For Lemur, the mechanism lived on even after the man had died (maybe). Maytera Marble's rusings indicate that she was once covered in flesh (this occurs even before she takes Rose's parts). [or maybe the godlings just have really big hands]. On another note, Has anyone made anything out of Doctor Crane's ghost as Silk/Horn reaches the pole in Return to the Whorl?
