This is a boolprop EPIC Legacy Challenge. Rules are here at the forum, or here on the blog. Basically it’s like a simplified, less-restrictive (and less complicated!) version of an Apocalypse Challenge – many things are blocked at the beginning, and through the generations you access different areas.
Chapter List is here.
The challenge is now COMPLETE! Final heir is Rizzo.
