In www.mythwolfage.com says that there will be new units:(Below are a list of units included in Myth III as we know so far:
Connacht
Damas
Myrdred
Warlock
Berserk
Archer
Dwarf
Myrkridian Pack-Mages
Moagim reborn
Ghoul Priest
Hollow Men
Wight
Trow Iron Warrior
Oghre)
So there wouldn't be Heron Guards!!!
I think it will be very dificult kill myrkridias without Herons.
I think it wouldn't be a good game without our Imperial Guards, the best warriors of the Cath Bruig Empire.
Is it possible that in Myth III there wouldn't be Herons???
Heron Guard King
