Nusi were domesticated by the Jasemi to provide a consistent source of the venom, as well for companionship and pest management. They resemble the Darmegon, aside from a few key features. They are smaller and gentler; and their tail-scythe has been replaced with a tail-orb, from which the coveted venom drips in enormous amounts. Additionally, they are flightless, only having vestigial wing-sockets.
The tail-orb is an evolution of the scythe-tail, designed to maximize the amount of venom produced without being a razor sharp weapon of death. This venom is collected by Jasemi, who use it for religious ritual and just plain getting high.
Nusi prowl the streets of Jasemi villages, playing with children and looking for small pests to eat. The Nusi is gentle and friendly, and enjoys being pet by any Jasemi it crosses.
Having been fully domesticated by the Jasemi, most Nusi have completely forgotten the noble predator myths and legends of their Darmegon cousins. Their lives are instead highly social, spending large amounts of time socializing with other Nusi and their Jasemi owners.
The Nusi are legendary gossips among the animal species of Prova and relish the opportunity to learn dirty news about their neighbors. A stray Pufbulo that would otherwise be Darmegon chow might be spared by a Nusi, and even helped home, if it delivers interesting news about the world at large.
They have had their aggression bred out of them by the Jasemi and are generally peaceful. Without their scythe-tail, a Nusi relies on its fangs and claws purely for self-defense.
The Nusi are as kind-hearted as the Jasemi and dislike killing, but they are still animals who must eat. Small rodents and the occasional lost Pufbulo make up the mainstays of their diet, but the Nusi are omnivorous and will feed with the Jasemi on vegetables when given.
