About:
This script does two things for the Rabinna NPC. First, if she has followed the player (AIPacakge 3) then prep her death to handle the possible contingences with her related quest. Second, if the player escorts her all the way to a character named Kilaya then she will leaver the player and follow that NPC.
There is a different version of this script that was released with Morrowind. My contribution here was to rewrite the script to account for Rabinna dying while travelling. These changes fix potential issues with the player journal while also accounting for quest items correctly.
