I don’t think they can call it Transylvania as it’s a real place. Transylvania is a state/region in Romania, just as Scotland is a State/region in the UK, and Ohio is a State/region in the US.
When Lancelot mentioned his land, it wasn’t called Britain, it will just go unnamed similar to Lancelot’s Kingdom.
I said “fictional” Transylvania. Big difference Crest. Adam Horowitz tweeted that it doesn’t matter what we think something is based on, work is fictional. Transylvania is always “fictionally” thought of as a monster’s world.
