Thank you for the new Community Use Download packages. I couldn't find Simoun, Ahmotep, Drelm, and Channa Ti in the Pathfinder Adventure Card Game Character download even though they are featured heroes in the Mummy's Mask set. I wouldn't expect to find these heroes in the iconics download because they aren't iconic characters.
Currently there's a blog post image for Drelm, but the other characters I mentioned aren't available under the Community Use Policy.
Hey Autoduelist, this is something we're looking into to add to our to-dos for the next update. Typically we have not included character artwork for the additional Adventure Path characters, and going to go ahead and do this when we have time.
