I have joked about "Dragon Effect" before, when playing through BioWare's vaguely parallel science-fiction and fantasy-franchises at the same time. Fan artist Andrew Ryan Art, though, has done one better.
Miranda as Morrigan I can actually kind of buy in to. And of course Jack is a dangerous-looking blood mage. For the full set, which includes Grunt, Garrus, Thane, and Wrex, hit up the artist's page. Meanwhile, I will wonder what kind of role Tali would fill in Thedas.
