The Fellowship of the Ring Werewolf

[Ina May the Midwife]

from reading OP, and some guessing. there will clearly be more than 3 wolves.

Where did witch king come from?
@Ina May the Midwife you are lore person, how likely is it for somebody to have come up with witch king as a baddie, and it actually to turn up as a baddie in this game.

For the Fellowship movie the Witch King stabs Frodo with a Nazgul blade which nearly kills him so yeah it makes sense from a lore point of view.
If William is a LOTR fan he'd prob know that tbf
