You might want to reconsider your project of writing it all on your own, then. I am struggling for a way to put this gently, but here goes: you have spent your Talossan political career accusing prominent Talossans of theft; betrayal; corruption; telling them that Talossa would be better off if they resigned and became inactive; etc. Surely you understand that such people are not going to be co-operative sources for your project; that such people will naturally assume that anything you write will be by turns dismissive, condescending, prurient and scolding of the people whom you have targeted throughout your Talossan political career. Why would anyone co-operate with someone who has made their Talossan lives a misery? Why would former citizens of the Republic be happy with having our story written by someone who disagreed with our various existence and characterised us as criminals? I sometimes despair that you show so little insight as to why, to be blunt, you will never be on friendly terms with people who you've spent your Talossan career characterising negatively.
A real Talossan history has to be written - if not by a completely neutral, dispassionate historian - then collectively to make sure of a balanced authorial voice. For this reason I implore you to rejoin, and help restart, the New Talossan History Project.
