A holdover from cultural Food tastes of Rokksher, where it was an abundant staple, the residents of Lake Arcania have an expensive taste for Bluefin Tuna, which is rare in Toosehn and is only consumed regularly by the wealthy, such as the Founder Families. Its rarity is due to the fact that it must be carefully farmed, as it was only introduced through an initial import from Rokksher.
Copycatfish is a dish eaten by Townsfolk to satisfy their cravings for Bluefin Tuna. Its method of preparation transforms the tastes of freshwater fish to better match saltwater pallets, but much of the nuance in the flavor is lost.
