These are going to be signs or things that may show a deity wants to communicate or work with you. These are signs from a mix or research and personal experience. If I'm missing anything leave a comment and I'll add it.
I personally work with Lucifer, Aphrodite, and Ares so I'll be doing theirs first. If you want a specific one, lemme know :)
