*Necromancers can build temples on Barren tiles, and the barren tile will still be considered "Barren" for attrition purposes. They gain base +20 growth and +1 profit from barren tiles.
* When a living necromancers army dies, it returns as "Undead" with -100 strength. Undead don't suffer attrition penalties and gain 20% strength bonus when fighting over barren tiles. An army will not respawn as undead if the necromancers have less temples built on "Barren" tiles than the amount of current undead armies.
* You can spend an action and sacrifice 50 population to plague the ground, turning a "Forest" or "Plains" tile in your territory to a barren tile.
* Necromancers can perform "Dark Rituals" to appease certain powerful demons and fallen gods living in the underdark and gain their powers. Rituals require the necromancers to perform a certain set of action on a certain turn to get that god's dark blessings.
