I suddenly question something that seems logical to everyone. If you look at the sample Reptilia faction in the core rule book you see that the Base Species has a certain bloodline and then at class creation another bloodline is chosen. While at the Anol class in the 1st Age book it says you can only select a single 1st Tier trait. So, technically the Bloodline trait is not a 1st Tier Trait if you look at the rules in the 1st Age book. So how does this work?
Or, do we miss a little piece of text that says you can treat Bloodline traits as 1st Tier traits for the purpose of Class creation?
something i missed when I replied on discord, if you have a bloodline in your faction and take a new one in your class it would replace the one from the faction and the associated traits and characteristics. effectively make a new blood line within your existing faction. so if you had dragon faction and want a class to be gargoyles. you would take gargoyles bloodline as a trait and replace the Dragon bloodline.
Taking a Bloodline Trait from another Lineage replaces Bloodline Traits from the previous Lineage and any traits that you may no longer have the prerequisites for.
