Ok, it get's a little complicated extracting the familiars.
Well, *doing* anything with them, anyway.
In Explorer, look for the blueprints in the template bif.
Just right click on each one (they are named nw_fm_*) and extract the utc to a folder.
Start with the OC, because I'm not sure all of them have been udjusted later. Work your way up to the 1.69 patch.
Now you have all of the UTCs... what do you do with them? If you don't already have the GFF Editor, grab it.
I use Roboius'
modified version.
If you open each utc in there, you can edit to your heart's content, and save them to the override or roll them into an erf.
