Shadow Army and Undead in FoW
The Undead and the Shadow Army in FoW attack each other, right? I remember using this to get past them easily when they spawn near each other. If I'm wrong in saying this, tell me and ignore the rest.
If I'm right, then why do they attack each other? Undead are ruled by The Undead Lich, and the Shadow Army is ruled by Menzies. The Lich and Menizies are both allies of Abaddon, so shouldn't they be allies of each other and therefore, their armies not oppose each other?
Thanks for any replies.
