@jedi7000nathan - I was going to do expanding boxes to explain all of the new scripts but then I found out I can't edit my posts on TWC :/
That particular script only happens if the player is neither Khazad-dum nor OotMM. In T.A. 2994 (turn 96), if the Moria provinces are controlled by KD faction, they will be given over to OotMM. This will only eliminate the KD faction in the event that all of their generals were in Moria when the provinces change hands. This script is designed to weaken the good factions overall at the expense of the AI's KD faction. The OotMM are a more serious threat in HE and may eliminate KD and Vale on their own before this script even happens. I am planning on implementing limited faction revival scripts so that the player will have the opportunity to revive dead factions such as Khazad-dum based on specific conditions.
