Namazu

Bursting forth from the earth is a catfish the size of a house. Its long barbels whip about frantically as it moves through the ground as if it were water.

Ancient creatures that glide through soil and rock, namazu are primal beasts superficially similar to the catfish. Despite their monstrous appearance and their ability to create earthquakes with ease, namazu are typically peaceful creatures’ the earthquakes they make are more likely to be caused during play or ritual under the ground rather than out of malice.

Namazu rarely encounter one another, so these occurrences are often a source of celebration. Such celebrations take the form of contests of strength and power, which can have dire consequences for other creatures in the radius of their magic and might. If confronted as an equal, rather than being fought as a monster, most namazu are apologetic and seek to engage in restitution for damage they may have caused. Unfortunately, they are often thought of as destructive monsters and treated as such, which can lead to further destruction in the wake of the namazu’s battles.

A namazu reaches up to sixty feet long and weighs a hundred tons. They are carnivorous, consuming purple worms and other burrowing monsters, but can go for a century between meals.
