There are some areas in Throne and Liberty that can be truly tough to survive in, making their respective Codex quests much harder to complete. Some of the areas that come up later in the game come with a lot of enemies that can easily overwhelm a player if they are not adequately prepared to fight for their lives. One of these areas is the Fonos Basin, which can be found just north of the game's starting area but really shouldn't be ventured into until players have reached the highest levels of the game.
