The only fish species to have survived the Holy Wars.
They currently reside in the only sea biome on the planet Earth (despite being an inherently fresh water species).
As such, they are a bit of a delicacy, and a pricy export from TCTD.
They are also highly irradiated, and sometimes mutated.
One mutant pike grew to be the size of a skyscraper and terrorized Highlanderland.
However, the Gentlemen who lived there constructed a giant steampunk robot to battle the threat.
A great feast of the fish's meat was had following the battle.
