I worship the Tritheistic of my main, Lady Athena, alongside Apollo and Hecate.
I have been having problems with setting up my altar for Hecate. I really can't think of any ideas to draw her (pose...what she wears, etc.) like I did with my Athena and Apollo altar. I plan on her holding a torch, and I don't copy images from the web because it doesn't feel personal to a level of worship for a goddess. It doesn't mean much to hit the copy and paste button, is how it feels to me.
Also, what gem would correspond with her? And would adder's tongue be alright for her altar? I have dried acorn for Athena, and lilac for Apollo.
