[World]
Fropian planet. A distant, habitable planet in the smaller galaxy of system 3C321. This Earth-like world consists of five continents and an expansive ocean, and orbits a binary star system. Days are precisely 48 Earth-hours long. On this world, two sentient species have evolved into a symbiotic relationship with each other, humans, and "skydogs" - anthropomorphic canid creatures capable of flight through wings and a body structure that borrows from avians, including hollow bones for weight savings. Interestingly, both races have adopted a time keeping system similar to that of Earth, however they follow a 48-hour day system similar to 24-hour "military" time on Earth. A year is 182 and a half days long, equating to the same amount of time as an Earth year. They use a standardized measurement system that strangely matches up to Metric.
The five lands are as such:
"Bryyo", the Land of the Ancients - this continent bears ruins of an ancient civilization. No current race lives here*, though it is oft explored. Rumored to be haunted.
"Noria", the Land of Sea - this continent has a freshwater spring forming a large lake in the center of it. Primitive tribal civilizations thrive here of both races.
"Meika", the Land of Storms - This subtropical continent is a constant target for thunderstorms and hurricanes. There are several coastal resort towns hosted by the humans.
"Arctos", the Land of Ice - This northernmost continent is perpetually frozen, only the hardiest of Skydogs call this land home, even in modern times.
"Vitri", the Land of Life - Modern cities thrive here. The human population focuses on this temperate-climate continent, and many Skydogs live with them.

*Not quite.
It seems the predecessors to the Skydogs have taken to a hidden native life on their home continent, even though their numbers qualify them for Critically Endangered status should they have existed on Earth.

[Skywolves]
In ages long past, some believe alongside the first humanlike creatures, a wolf grew wings and the ability to stand upright. Or so the legends go.

[Skywolf flight]
Unlike the finely adapted Skydogs, Skywolves have a very heavy body structure, and relatively uniform wing design. Owing to the fact that it's HARD to lift such a heavy body, they can only fly relatively short distances, and such have evolved a wing design favoring short hop-like flights. They have not adapted the short, high speed wingbeats of Skydogs, and such actually flap their wings. They are also capable of taking off or landing without running.

[Haunted?]
The continent of Bryyo has earned its reputation for being haunted due to the secretive actions of the Skywolves, who really just want the humans and skydogs to leave them alone and stop tromping all over their lands!

[Navigation]
Skydogs have an innate 'compass' and finely tuned motion sensing organs - like the ones in your ear - as well as being attuned to atmospheric pressure for navigation over very long flights. Skywolves lack these, partly due to the horrible magnetic interference common on their home continent, and partly due to the fact that they so rarely fly any kind of distance.

[Religion]
Skywolf culture follows a Wicca-like religion that involves worship of a God and Goddess - the Goddess sometimes being perceived as a principle diety, though Skywolves believe both to be equal Four elemental spirits are also worshipped, with the God and Goddess serving, together, as a fifth. A strong emphasis is placed on "Mana", a magical power that they believe lives within all living creatures, and can be borrowed in times of need. Skywolves who use their Mana power are expected to "pay back" the land somehow for the energy they used.

[The Pack]
Skywolves, due to being isolated to one continent, consider themselves to all be part of one gigantic pack, headed by a prominent, huge, and really strong Alpha, served by a small group of Betas directly under him or her. Each family unit is headed by a Delta, who helps coordinate with the Betas to ensure the peace of the super-pack.

[Values]
These creatures place strong emphasis on the ideas of Honor, Dignity, and Respect. Honor your neighbor, family, Pack, and self.
Carry yourself with Dignity, and do your best to preserve others'.
Respect all living beings.
Only in times of war or hardship is it considered okay to deviate from any of these.

[War!]
An inadvertant grounding of the pleasure cruise ship Lady Monarch was perceived by the Skywolves as an intentional act of war by Humans and Skydogs, and they reacted accordingly. "Combat" was fought for all of about two days, before peace efforts were made, and all mostly returned to life as usual. It didn't take long before they opened a tourist resort near the docks.

Part of Rex's breed's adaptations to the swamp life is that their blood is thicker than normal, to better resist being sucked out of them by the omnipresent parasitic insects. However, this blood does not flow easily through his body, and renders him vulnerable to fatigue. Swamp Wolf life is slow paced and seemingly easy going by human standards because of this, and all hunting and battles are done by way of ambush tactics and VERY short skirmishes. His flight is similarly extremely limited. Rex is only able to "jump" and "glide". Attempting to actually fly will result in rapid wing fatigue and a crash.
Like all Skywolves, Rex needs continuous access to Mana energy to remain sane. Deprivation of this will slowly drive him mad (1 month), or even kill him (1.5 months). He can use his pendant necklace to stave this off for 1 week before it is depleted.
