Is Honor-mode permadeath?
I also have DOS2 but I never finished the very end. I might replay DOS2 if I need a break from BG3. I remember Fane was my favorite in DOS2! I healed him with poison <3 :B I played Fane origin with Sebille, Lohse, and Red Prince in my party. Now I'm wondering if I did myself a dis-service, by playing Origin Fane instead of just having him as a party member.
Yup. If it's anything like DOS2's Honour mode it will just be Tactician difficulty, but with one save which will be overwritten as soon as a companion is downed.
As for wondering whether you did a disservice by playing Fane, nah. I've played all of the Origin characters (Sebille being my favorite) and they're all worth playing as they all give meaningful insight into the story. Fane in particular has some unique main story choices which are not available to any other companions, which is why he ended up being perfect for my evil playthrough
