Where do I find quality information on Gods/Goddesses/deities/entities etc? Is there one particular website that lists them?
Just use the search button, this forum is filled with infos
Just look it up on Google and do good old-fashioned research.
Lesser Keys of Solomon is a free book and good start
You can always start with mythology books and work your way up from there. There’s a plethora of information on Greek,Norse, Egyptian gods (for a small example- by no means a complete list) on websites that people have made specifically to answer your questions! Just go out there and look on google. It’s really not hard to find information. A quick pagan god search on Bing could prove useful
