Based on NinjaLights suggestion (Thank you for that, Ninja!), the two Sylvanian vampire factions have now been updated! Three changes to them:

• The Sylvanian provinces:
  When taken over the two provinces in Sylvania, their name will change into Grand County of Sylvania.
  
  
• Middle step:
  After that, as a bonus level for them both. When taken over 16 regions in total (little under half of the total Empire land) their name will change into Midnight Aristocracy.
  
  
• Level 3 name:
  Both Vlads and Mannfreds level 3 name have now been changed.
  The Drak-Carstein Empire for Vlad
  The Carstein Empire for Mannfred
  This where meant to showcase how, specially in Vlads case, he rules with Isabella. Which had the surname Von Drak before. We know those names aren't 100% perfect, so feel free to give other similar suggestions.

Because been sick for 1-2 weeks now, I haven't been fully able to do proper mod work. However, I still want to put out an little update! :P So the mod have now been updated with the following:

• 1.Added full name sets for Greybeards, Karak Drak and Laurelorn.
  You can see their lists in their faction tab.
  
  
• 2. Individual name sets for each of the playable greenskin factions. Meaning one for Grimgor. One for Skarsnik etc. And a different set for all the unplayable ones ones.
  
  
• 3. Mixed in region count rules where felt it fitted more. For a more natural name change for factions as you play.
  
  
• 4. Some edits in set names for Reikland and the Sylvanian vampires.

Feel free to post feedback on any of these changes in the comment section! You all are an amazing help in making this mod better and better! :) Thank you all.

Also feel free to suggest more places the region count rule would fit more than the province list rule.
