First of all, I apologize if this question has already been resolved in the forum.
I wanted someone to explain to me how the formations supplement Haemonculus Covens work.
When using a formation, will my detachment is only that formation? I can not include any other unit and / or detachment of Dark Eldar?
"From the darkness of the Webway, countless beings and organizations overlook the realities plaguing the concepts and laws of normal and common knowledge and belief of the lower races. Since those corners of unreality is where the lost child has emerged distant aeons ago: Nyarlath Ircht the Lord of the Shadows Dim has returned bringing the missing Kabbalah of Crawling Chaos. That worship of darkness that makes remote times embarked on a journey through the Webway looking for the absolute pleasure.
Those thirsty warriors deranged sadism and madness back to Commorragh between blackest leftovers, impossible to penetrate the light fades caged suns. They are the children of darkness, and returned to plunge all reality in his demented nightmare."
