Thank you, Adalil. It was totally inspired by Necron-map games like Mechanicus and Space Marine Adventures. I have enjoyed those a lot lately.
As far as special skills and the like go, yes, it was a space thing, but also a asymmetry thing. With the Guardians having a monopoly on the abilities and special powers, I was hoping the simplicity of the variation of the Explorers would thematically contrast it. Secretly, I would love for everyone to have cool powers. That is a lot of fun.
