I don't know a thing about Taro, aside that playing cards originated from them. But I found this interpretation interesting.
SYMBOLISM - 5/13 - Blackwall - Judgement

Judgement is one of the most powerful cards in the deck. It is related to spiritual and physical matters and is at the base of all decisions and actions one takes. It represents rebirth and awakening of the spirit.
The Judgement card is often represented by a powerful person in the sky accompanied by a mythological creature, such as a phoenix or griffon. The person (in this case, Blackwall) is entitled to cast judgement on those beneath him (the darkspawn). There are often people beneath the figure in the sky, but the fact that Blackwall is judging darkspawn and not people means that his intentions are purely to assist the innocent, there is no question of his morality. The presence of the griffon is interesting because in the DA universe, the griffon is extinct. The much more traditional creature used in the Judgement card is the phoenix, which rises from it’s own ashes. Could potentially be a nod to the griffons coming back from extinction.
Blackwall is seen in full Warden armour, riding the griffon and slaying darkspawn, he is in the role of a protector. An interesting point to make is that the ‘judgement’ referred to in the card specifically connects to the potential ‘judgement’ one may receive at the end of one’s life, according to many religions and beliefs, including the religion in Thedas. The Judgement card often appears in readings where it represents resolution of past issues and the culmination of all that has been, and all that will be.
Another aspect of the card is meditation and coming to an epiphany through reflection. It is a card of absolution, putting the past behind you and being able to confront any personal ‘demons’ in order to clear the slate for a new way of thinking, living or being. There is no bias in the card, it is like the Justice card in its passion and actions, but it is not anywhere near as careless or blind.
To summarize the card, it is about the awakening and cleansing of the spirit. It is about having a clear heart, free of sin and regret and being able to resolve, then move on with a new-found knowledge and peace.
