That would be too obvious, not a good easter egg then :/ Probably will go with just a random event that pops up "An undead creature volunteers to lead your army... He goes by the name Richard. With him he has an Elf, a Cow walking on his back legs... etc. etc."
Sometime I wonder if you're batshit insane Groogy xD
Then i figure: I aint much better my self, carry on
