I really like your idea of the three phases of his life! Which cards would you pick out for them?
I won a free art commission for a tarot card from an artist on Tumblr that I set up for him post-judgement (Five of Swords), but I've no idea when it'll be done.
Five of Swords
- losing your moral compass
- letting ends justify means
- sacrificing integrity
- losing sight of what is right
- achieving a dubious victory
- having an "us-against-them" mentality
- creating ill will
- experiencing conflict
Well, there were some cards a while ago showing DA:I characters and their weakenesses. Blackwall and gold, Dorian and men, etc.
Maybe such card could be done for Samson? His weakness is not even lyrium, in my humble opinion, but his hatred against Meredith. Later on, he came to hate the Chantry due to his recruitment by Corypheus.
So the card could show him in two moments:
The Past - Samson as a guttersnipe, looking longingly at the Gallows or the symbol of the Templars (the sunshield or another symbol), with blue lyrium in one of the margins of the card.
The Present - Samson as the knight in red, with a vengeful expression and the Templars' heraldry behind him, looking dark, with red lyrium in the other margin of the card.
The images of Meredith and Corypheus could be hinted at in each side, since they were the forces responsible for the chages Samson underwent.
Other fans may have more ideas for the card. Let's wait for them to manifest what they have in mind.
