What confuses me is that they haven't even done anything with Malekith after Fantasy. You would expect after all the buildup from End Times that he would serve a pivotal role in Age of Sigmar, but he's mostly a side note in comparison to Morathi, who actually does stuff. Tyrion and Malerion are the only Incarnates who don't do shit. I assume Tyrion isn't available at the moment because all their resources were spent on
V-Posing Teclis, but Malerion (Malekith renamed probably so they can trademark this name/don't want to compete with Marvel) was ghosted for 6-7 years. He still doesn't have a model, army or statblock.
