Well, according to my path, it relies on which one of the realms are you suited, being those: 1- Violence, 2- Creatures, 3- Woods, 4- Espace, 5- Desire, 6-Wonder, 7- Storm, 8- Graveyard, 9- Law, 10- Hunt, 11- Destiny and 12- Matter. After the realm being found, you usually use the symbol with correspondent number with your realm. Exemplifying: I'm a servant of Danna, godess of the Storm and queen above the 4 stances, being my realm the 7th. So, I usually use a heptagram or objects with the Storm crafted in it.
I think it's quite confusing, but hope it does help you someway.
May the Storm guard your way, matey.
