OK, so looking into this it looks like I conflated the statement on page 119 that many Mulhorandi Tieflings are believed to be descended from the gods with the suggested alternate aesthetics from the sidebar of pahe 118.Can you give the precise quote, please? Or page number?
There's reference on p. 118 about alternate forms of Tieflings (though none with animal heads), and a short sidebar on p. 119 about Aasimar (but nothing about animal heads).
