Can a fiendish spawn in rookgard?

Question

I was looking for fiendish and seems like it is on rookgard, however i dont have a way to confirm it since  there is not spells on rookgards but everything was pointing to rookgard

Answer 1

No, they can't.

Only creatures which 1) have the occurrence common 2) are not part of a raid, and 3) are not located on Dawnport or Rookgaard, or in boss lairs as well as in arenas can become influenced or fiendish monsters. Also, only lootable creatures can become fiendish monsters
