How does CK3 revive the family?

You find the ID of your extinct family member in the file, and there will be a clan ID below. You can create a villain at will, or use the villain as a tool. This villain must have a clan. You change the clan ID of this villain to the ID of the extinct family, save the file with the suffix .ck3, and it's OK to enter this archive. The main thing is to ask for the ID of your role or the ID of the same clan role.

With the role ID, you can search the clan code, and then it will be easy.
