Great conversion for Birthright by Oraibi. Even if you have no interest in this setting (mad fools) worth seeing just for the great work done 
The more I read this the less inclined I am to do my own conversion work!
A tweak here and there for personal preference and happy days 
Thanks.
It's meant to be tweaked so feel free to tweak away. I happily acknowledge that not everything is going to be to everyone's tastes -- this is tailored towards mine right now.
