The Kainale Era

Cities have tall walls with defenses designed to repel Kainales, and castle-style gates that open or close depending on the status of the approaching Kainal. Identification is based on species and behavior: fox Kainales are generally seen as friendly, while wolves are considered neutral — how they're treated depends on whether they attack in the moment, with no fixed rule. Defenses can injure or even kill a Kainal if it becomes too aggressive. Not all Kainal families live within the walls; some prefer the wilderness instead.

A small number of Kainales are born with elemental powers (such as breathing fire), the result of an anomaly or "birth defect" — it's not hereditary and isn't tied to any particular species; it occurs randomly. These powers are exclusive to the original Kainal form: if a Kainal with a power is also a Kainíbrid, it loses access to that power upon transforming into humanoid form, since the power is tied to its animal physiology.

Kainibrids are a special variant of Kainales that can voluntarily transform (with no limit on how many times) into a humanoid form. This form retains full human anatomy, but with a skin color different from normal human skin and residual animal traits that vary by individual (tails, tentacles, claws, etc., depending on their base species). The size of the humanoid form is proportional to the size and age of the Kainal in its original form (a young, small Kainal produces a small humanoid). Not all Kainales are Kainíbrids — it's a capability only some possess, typically inherited within specific family lines.

Kainales are giant animals exclusively from the wild canine family: wolves, coyotes, foxes, jackals, etc. (never domestic dogs). Their name combines "Kaiju," "Titan," and "Animal." They have a maximum height limit of 90 feet (~27 meters). Unlike ordinary animals, all Kainales retain fully human-level intelligence and speech, behaving and reasoning like people — a hostile Kainal can be just as calculating and cruel as a person, and a friendly one can form real bonds and hold genuine conversations. They live in family structures similar to real wolf packs: the founding pair (father and mother) holds the leadership role, while the rest are their offspring, with responsibility increasing with age.

The Kainale Era takes place in a modern-day world where Kainales have always existed alongside humans — there's no origin event, they're simply a normal (if dangerous) part of nature. Human society adapted by building walled cities with defenses capable of containing or repelling these giants. Kainales fall into three behavioral categories: friendly, neutral, and hostile, though this can vary by individual beyond just species. Users can choose to play as a human survivor or as a Kainal, experiencing the story from either perspective.
