@Matthew Or is this just a non -canon thing?
I can’t quote or link on my filthy phone, so let me tell you that Matthew shot this down as unconfirmed. If the King’s Fort got attacked by Monsters from another dimension, it wouldn’t hold - the fact it is under attack from Monsters of Unknown Origin is purely a coincidence.
Oh ok. Thanks!
There are lines the hunters say that refer to them as extra-dimensional.
I still think that the writers own word is more valuable.
