What do you think it should present? Me personally, I'd have a cliche, but effective image of the hero(at least one possible version of them) and the supporting party lined up in a similar way to the Justice League in the opening of their show, with the hero front and center, all of them with their weapons drawn or channeling magic. Above them ,Solas/Fen'Harel overlook the heroes and glare menacingly at them, or glare menacingly at the viewer. Or maybe we don't see Solas at all and instead we see how the Dalish see him, as a fierce and cunning wolf. The rest of the cover is full of spirits, demons.
