How about a mod allows players to roleplay as some monstrous feral ghoul master/ Necromancer.
The player can collect feral ghouls into their army that can be can commanded to defend or attack for them, even against other feral ghouls.
The player of course will need to obtain some feral ghouls for their service by getting real ones or by ghoulifying human/civilized ghouls using some kind of radiation weapon or necromancy.
And eventually allow the player to make his ghouls stronger so that they can transmit their mutagens so other "dead" humanoid NPCs growing the ranks of the player.
It must all come at a cost through the player's reputation, relationships and sanity in co-mingling with the feral dead.
If Anybody can make or point me into the direction of a mod(s) like this, let me know it will be greatly appreciated...
