While searching the knowledge base of ESO, a friend of mine stumbled across some curious information about Tamrielic fish.
The question is, why certain ocean fishes can be catched in Cyrodiil, while Cyrodiil has no ocean.
According to the knowledge base, Cyrodiil's "southwestern fjords" are filled with ocean water, and that's why ocean fishes are common around there.
It also mentions that said fjords were created after the thawing.
Now, I wonder... when was Cyrodiil frozen over? What fjords is the game talking about?
