As in topic ,
I though how many of us would love to have crypt , as house for our vampires or werewolf pit ? With bloodstains everywhere cattle to feed on? Undead guard or alliance guard of choosing (like you could choose which race from alliance)
So you could makcan they way u want them to patrol move behave etc ,
And some furniture related to crypt vampires undead werewolves , something to scare ur friends ! Like trap when they enter it hit them low dmg etc :P capturing npc for torture ! Or beheading them !
