Carthal is Mythron's main porting city since the fall of Tomeu.

Carthal has walls surrounding the city's Western section, with the eastern open gladly for trade. Only half the population actually resides in Carthal, as many are tradesmen, merchants, and even outlaws. It also is home to the majority of Mythron's military dockyards where ships are constructed. From port to port there are salesmen trying to make a decent profit. Mythron has also set up the coast near Carthal with their most advanced defenses, and Carthal has been deemed impregnable by some.

Carthal hosted the Tourney in 2014.
