Man in the Funny Hat
Hero
Made up my own from scratch once many years ago. Made a master list of all the different "deity of X" or "deity of Y" I wanted to cover and one by one created a comprehensive pantheon. Unique names, personalities for them, relationships and rivalries among many of them, and yet able to fit as the same pantheon for most any sentient species. Greater gods, lesser gods, demigods... I was very happy with it and proud of it.Take any gods from across any dnd pantheon, but only 1 per slot. No "two gods of the sun" kind of thing. One pantheon to rule them all. Whose on your list?
Problem was, I had the whole thing on a laptop along with a lot of other gaming files and it got stolen. Didn't have the files backed up. I tried to reconstitute some of it from memory but it was MONTHS of work, maybe even a year or more putting it together in the first place and it all faded away.
Not only did I get much better about having backups to computer files from then on (hard drives at the time were also reliable in that it was never a question of IF they'd crash but merely WHEN), but it kinda gutted me in terms of creativity for a number of years and I just went with default pantheons from published game worlds.
