Double Vampire Bloodline Lords
This mod is quite simple, it edits the script that’s triggered when unlocking a Bloodline so that it gives 2 Lords instead of 1. This means you can now get 6 Lords for each Bloodline. Each of the Lords unlocked should have random traits and names like normal.
Note that because this changes the script event that fires when unlocking a Bloodline, this mod will not retroactively grant additional Lords for already unlocked Bloodlines.
