Fairly vague to avoid spoilers. There are a couple of panels in this issue that highlight the founders of the federation. They both show members of FIVE species. Human, Andorian, Tellerite, Vulcan and... someone else? At first glance they seem human but actually they seem to have a pattern on their bald head, veins/tattoo I’m not sure. Maybe Deltan? Alpha Cetauran? I’d post a picture but not sure if that’s allowed for something that just came out today. Anyway it confused me as I thought it was fairly well established there were 4 founder species.
