I keep staring at the portrait of the new origin character... is it maybe a bird? Raven? In theme of the new Panel From Hell?
If that is a bird, and if the middle word is red as some have suggested, it could be the red wizard origin that got datamined, and it could be Sefris of the Hidden Ways with her Raven familiar, an ex red wizardess from the Venture into the Dungeon Commander Deck in MtG.
