Let's see... Shepard would be The World, Tali would be The Moon, Garrus is The Emperor, Mordin is Justice, Liara is The High Priestess, Grunt is The Fool, Wrex would be The Chariot, and Thane is The Hierophant. Not sure if these are all that accurate, but this is what I got after thinking it over for a bit. Most uncertain about Mordin and Tali. Hope you don't mind.
