Thanks. When we were developing the look of the tiefs we wanted the fiendish bloodline to manifest in different forms, so not always horns or batwings, barbed tails, etc…

To add to this, I think it was Zeb Cook who created the race (you’d ha e to ask him) and Dana Knutson provided concept art. They have fiend in their lineage so it would manifest in various ways: hairless, spikes, horns, tails, cloven hooves, androgynous…

I mistook his direction a bit, thinking that many were the descendants of succubi or incubus and so often drew them scantily clad, which I would vary now. Anyways, here’s the first drawing I ever did of one alongside Dana’s concept sketch. pic.twitter.com/t64m5L2yGq
