Anyway, now that I have time, the tarot explanations, as best I remember them.

0 The Fool : Dante
Dante at the beginning of DMC3 in particular - brash, a bit stupid. Dives headlong into things without thinking, as well as it being the beginning of the game.

1 The Magician : Vergil
Power of male creation through willpower, control. Vergil makes Temen ni Gru appear through his strength and power, and invites Dante in. Control is what he has, and also, I think, what he desires.

2 The High Priestess : Lucia
Secret knowledge. Lucia is mysterious, in ways she doesn't even know about at the beginning of the game.

3 The Empress : Eva
The mother-figure, harmony. She is Dante and Vergil's mother, and to them represents caring, happiness

4 The Emperor : Sparda
The father-figure, authority and power. Dante and Vergil's father, who to them represents ultimate control and power.

5 The Hierophant : Legendary Dark Knight
The upholder of divine will on earth. Sparda as the Legendary Dark Knight represents a sort of higher ideal, as he seperates the demon and human worlds from each other.

6 The Lovers : Dante and Vergil
Union of opposites, two halves forming a more perfect whole. This one spawned the rest of the set, so I may as well just quote straight from the DMC3 manga: "The two sons, which were meant to be one." ... "Are you trying to say I'm only half a man?" "No. I'm saying that you and Dante need each other." Only together are they complete.

7 The Chariot : Agni and Rudra
Victory, mastery of opposing forces. Agni and Rudra together are strong, even though they represent different elements - wind and fire.

8 Strength : Lady
Youthful vitality, but at the same time the innocence that comes with it. Lady is strong, but still isn't completely sure of what she's doing. (I totally wanted an image of her on her motorcyle, but I couldn't find one.)

9 The Hermit : Matier
Quiet, hidden wisdom. Matier knows secrets about Sparda, but speaks little.

10 Wheel of Fortune : Divinity Statues
Fortune, windfall. The statues are where you get stuff! I'd call that good fortune.

11 Justice : Nelo Angelo
Equality, fairness. The black masked warrior who steps out of the mirror and challenges you to a fair fight.

12 The Hanged Man : Trish
The inability to change. Trish is Mundus's servant, and follows his orders without really thinking for herself for most of the game.

13 Death : Arkham
Change, rebirth through destruction. Arkham sacrifices his wife to gain demonic powers, and desires to reunite the demon and human worlds and plunge them into chaos.

14 Temperance : Rebellion and Yamato
Tempering, patience. On one hand, you have the kind of bad pun of tempered steel, but Rebellion and Yamato together can also represent the moment at end of mission 19, where Dante and Vergil put aside their differences and fight together.

15 The Devil : Mundus
Ultimate evil. Mundus is the lord of Hell, pretty much. Also the source of everyone's problems.

16 The Tower : Temen ni Gru
Sudden destruction. Temen ni Gru (as well as being a tower) basically shows up out of nowhere, and is the portal through to the demon world, and all the destruction that entails.

17 The Star : Devil Star
Secret wisdom, imortality. The devil stars fill your DT gauge, which is in itself a form of immortality, and is a higher, ancient sort of magic.

18 The Moon : Jester
Hidden enemies. Jester shows up taunts you and draws you deeper in, and then turns out to be Arkham and totally screws you over.

19 The Sun : Pendant
Happiness. The pendant represents one of the few happy bits of the series - Dante and Vergil's childhood, and love of their mother. It also brings Trish back from the dead, which is happy, too.

20 Judgement : Force Edge
Questions answered. The Force Edge and what it does is the big mystery of DMC1, and in the end, we finally find out it's powers. In DMC3, it's what waits to seal the gates between the worlds.

21 The World : Dante's Office
The end, coming full-circle. Both DMC1 and 3 both start and end in Dante's office, and it's the most over all sort of ending.
